I find the experience of watching these SpaceX videos very emotional. There's something really inspiring both from an "exploring the universe" perspective and also just from the human side of all of the effort that went into them.
The first video that really got to me was when they landed multiple boosters. This one as well, especially seeing the rocket take off with every booster firing when compared with the first Starship launch when you could see that some failed to light. It's like watching your child take their first steps, and then seeing them win an Olympic medal for running. Just incredible stuff.
For those of you who like dubstep, start the following video first
https://www.youtube.com/watch?v=t2eBMuL0C2o
then 3 seconds later start to watch the (muted) SpaceX video from OP's post
and thank me later. ;-)
OK, that's downright creepy. Especially that the singing starts with the lyrics "holding on" at the exact moment the booster is caught by the chopsticks.
Nice, how did you find a music clip with such a good match across the whole video? Or are you saying you know that SpaceX media people were using that as test music when cutting theirs?
And in 2002 a neuroscientist hooked a camera to a blind man's brain and he could see well enough to drive a car around an empty parking lot without running into things. And yet there are still many blind people.
Doing something cool once doesn't impact civilization. Doing it affordably at scale does. If Space X can do the chopstick landing reliably and integrate it into their operations, then that will be impactful - and change civilization.
Is the whole point of this thing to land the first stage on the moon, or just the Starship? My understanding is that it's just Starship, and the first stage will always return to Earth. I think one of us has a very confused understanding of the whole point of the thing.
They did? I've not heard of that, and a cursory search isn't finding anything. Got any more info on this, which rocket, etc? I'd love to learn about that.
I think it's a really responsible decision by SpaceX to not put their StarShip stage into a full orbit until they have demonstrated the ability to get it back out of orbit.
They should be applauded for this, along with their iterative approach.
Note that this next test will demonstrate re-light of the engine in space at micro-gravity. This is the demonstration needed prior to putting the StarShip in orbit. We'll probably see a full orbital test for the flight after this one.
They could have easily put previous tests into orbit - it's a fairly minor change to their existing regime and they have plenty of fuel to use.
Not into space things and while this is cool i wonder what the great significance of this is? I see lots signaling how great this is and it's lost on me.
Totally reasonable question. This is the first rocket ever that will (assuming further success) land in its entirety back on the launch pad, refuel, and go back to orbit the same day.
Imagine that every time an airliner landed its cockpit was destroyed and you had to build a new one. A fully reusable airplane would be a transformational improvement. That's the level of achievement we're talking about here.
That seems like a stretch. What is the actual turnaround time for Starship? fwiw the Shuttle had a lot of lofty promises of reusability that were technically true as long as you didn't consider how long the turnaround time was.
The shuttle boosters required rebuilding / refueling (which is solid rocket goop) and the fuel tank was completely lost and required rebuilding. The head shield tiles were extremely fragile on the shuttle.
It was never a fully reusable design, just more reusable than before.
SpaceX plans to have no parts that are lost each flight and is working to make the tiles mostly standardized and less sensitive to faults.
Are they going to replace all the tiles before it can relaunch? And what about the engine nozzles? They must be taking quite the beating.
No doubt SpaceX has very smart people working on this and I'm not an expert in material science, but I just find it hard to believe that same day turnaround could be possible. If true, that would really make us a confirmed space faring civilization. We could actually start colonizing Mars.
The heat tiles are reusable, just like the Shuttle's. They are basically just a material that insulates very well, instead of a traditional ablative heat shield that burns away. With the space shuttle they ended up spending a lot of time inspecting each tile for damage and replacing cracked tiles. SpaceX has a modern iteration of the same material, hopefully with fewer cracks.
Other factors that work in SpaceX's favor are 1) that most launches will be unmanned, meaning they can take bigger risks than the Space Shuttle program; 2) that the steel body of Starship can handle higher temperatures than the Space Shuttle's aluminum, so a compromised heat shield is more tolerable; 3) for now they have a secondary ablative heat shield below the tiles (that does have to be replaced when it gets used, but that should only happen when tiles fall off)
No, those were separate craft, on opposite sides of the country. It demonstrates an ability to manage multiple missions at once, but not rapid booster turnaround.
For context on JumpCrisscross's comment in this thread: the 4 hours is between two separate launches on two separate rockets. This is absolutely not refurbishing and launching the same rocket 4 hours apart.
Seems like the actual record for turning around the same booster is 21 days, which is still quite impressive.
Some of SpaceX's first stages are getting close to the individual Shuttles' launch counts, with substantially less turnaround time and cost than Shuttle ever had.
Starship has work to do, but it's hard to argue they're not at least on the right path.
With the Falcon 9 they're already at over 100 launches this year. It's multiple rockets, but the turn around is pretty quick and getting quicker every year. They're designing starship from the start with same day turnaround in mind. I wouldn't bet against it I guess.
It's a good question. The hurdle to clear for same-day reuse will be the heat shield. SpaceX hasn't yet demonstrated that Starship can reenter the atmosphere and remain fully intact. Doing it while sustaining near zero wear on the heat shield will be even harder. But I think it is not impossible, and I don't know of any other obvious blockers for same day reuse.
Zero wear is not necessary. The tiles can be thicker than the minimum, and be reusable until they wear down to the minimum. Like the brake pads on your car.
They'll likely reuse the booster on the same day well before the starship portion. No heat shield on the booster. Some starships will likely stay in space for a long time before returning.
It was a flap hinge that burnt through, not the flap. They have a solution for block 2 which we'll likely see in test 7 -- move the flap slightly further back so that the hinge isn't in direct flow.
oh, you mean like actual flaps of pretty much any aircraft. doh! i was thinking it was like the folding of the wings for planes on an aircraft carrier. sometimes my brain, boy, i don't know
For the Super Heavy booster, SpaceX is targeting a <1hr turnaround time. For the ship, it gets a bit more complex. Ships have to make complete orbits before returning, and generally they have to be loaded with cargo as well. Tanker Starships for lunar/Mars missions will probably have pretty quick turnaround given that fuel can be loaded on the pad; other ships will have significantly longer turnarounds.
SpaceX already launches multiple times per month just to maintain Starlink. That will be much cheaper with Starship while enabling larger and more capable satellites. In fact, it's likely that one of the reasons SpaceX built Starlink is to create their own customer (and spur competitors) to plausibly use a significant fraction of Starship's capabilities. None existed at the time.
In the near term the biggest reason to do multiple launches in a day will be orbital refueling. This is required for sending much, much larger payloads to the Moon and Mars. It will require on the order of 10 launches to fuel up one moon lander in orbit, and obviously doing that as quickly as possible will be beneficial. NASA has already committed to this plan for Artemis.
> It will require on the order of 10 launches to fuel up one moon lander in orbit
Require, or just make comfortable? Saturn V had the lift capacity of "only" a couple of Falcon Heavies, but was enough to carry astronauts, a car, a lunar lander with enough fuel to take off, and a command module.
We're not trying to do Apollo again. That would be easier, but we want to build a base this time. For that we need to send a lot more mass and it needs a lot more fuel.
The HLS (Spaceship) will need many refuels at orbit in order to get to the Moon and back. That means at least a dozen of fully-loaded Heavy launches to LEO just so each one of them can load a bit of fuel into HLS. The fuel in orbit can't sit idle for too long, or it deteriorates; I haven't found a limit on days for that, but a week-long launch window is considered a dealbreaker, we're talking a dozen Heavy launches in a week.
It's either a short launch window, or at least 6 Starships built and launched twice in ~10 days. Don't count out on SpaceX building 12 Heavy Starships just for that Artemis mission.
If we want to establish long term bases on the Moon or Mars then yes, you need not only to send crew and habitation modules but ongoing supplies and equipment.
Other use cases include launching and maintaining satellite constellations (Starling / Starshield), and launching singular large payloads like space telescopes.
Even for smaller payloads, having both the first and second stages be reusable will reduce launch costs.
200 years ago, there was no need to use electricity. 100 years ago, there was no need to use a programming language. 30 years ago, there was no need for gigabit wireless Internet.
Counterexample: space stations. We've had small manned space stations for decades now, but no real application for them. They're national prestige items only.
I think the economics of space are are much more likely to be transformed by something like https://www.longshotspace.com/. Rockets are complex, still costly, and polluting.
The problem with space guns is you can't just yeet rocks into orbit. Any orbit that starts at the surface returns to the surface. So you still need a disposable rocket and avionics and fuel in every payload to change the orbit once out of the atmosphere. Only now the rocket needs to survive being literally shot out of a gun and then traveling at orbital velocity in atmosphere. That puts a pretty high floor on the cost per shot.
If you want to look at someone that is further along on a concept like this you can look at SpinLaunch. Exactly what it sounds like with a gigantic centrifuge to spin and throw things really fast. But they are still throwing a small two-stage rocket.
The big thing is that it dramatically reduces the cost of shipping things into space. Previously it was difficult to ship anything much larger than a compact car in to orbit. Now you can ship half of a basketball court into orbit, including all the vertical space.
Until very very recently the roughly bus sized ISS modules were the largest habitable spaces we could ship to orbit (although Skylab in the 70s were basically repurposed Saturn V fuel tanks and also big) so now it's possible/probable we can ship 20 people to space, and have moderately comfortable accommodations for them.
We can also ship mining equipment and substancially more supplies to the moon. Or mars. We went from using pack goats to 18 wheelers to ship stuff in space. The pack goat can ship a handful of hand made silk scarves and Faberge eggs over the Himalayas, but the 18 wheeler can deliver everything from socks and tshirts to cell phones and big screen tvs and trucks and lawn mowers. This really opens up space to more than the highest, most bleeding edge science and we might actually see more than 100 humans in space at the same time, in our lifetimes.
Well, basketball courts have a ~12m diameter 3-point line, and the inside of a starship is ~9m. Swimming pools are mostly rectangular from the outside observer's perspective.
If you go to space, 90% of the cost is the rocket (depending on your accounting). If rockets can be made reusable, then you can drop costs by 90%, to first order. Cheaper rockets means cheaper satellites for internet and sensors and stuff.
Also, as mass to orbit gets cheaper you can build your payload more cheaply. Many compromises in complexity and material cost are made to minimize payload mass - we'll be able to launch cheap and heavy satellites and probes into orbit instead.
It's a rocket in the same ballpark as the Saturn V but where the two stages can both be recovered and re-used.
SpaceX has demonstrated being able to fly the same rocket stage dozens of times with minimal refurbishment with their Falcon 9 family of rockets, but they still have to build and discard the second stage of the Falcon 9 for each launch.
Starship scales that up in magnitude and adds second-stage reusability.
Price decreases significantly when you can reuse.
This rocket is the same size as the ones that brought the Apollo missions to the moon, but will cost significantly less because they don't have to build one every time they launch it.
Imagine if a round-trip flight from the US to Europe didn’t cost $500, but only $5, unbelievable, right? This is exactly what Starship will do to space travel. Many things we see in sci-fi, like lunar and Martian cities or orbital cruise ships, could soon become reality.
Personally, I can’t wait to see a massive, kilometer-wide telescope in space or nestled in a crater on the Moon. We might finally figure out dark matter, dark energy, anti-gravity.
It's just an outlandish overly optimistic mishmash of different concepts.
Let's start with your analogy:
> Imagine if a round-trip flight from the US to Europe didn’t cost $500, but only $5, unbelievable, right?
If you mean to use this to explain that what today costs X will in the future cost 0.01X, you're probably right.
But a more accurate analogy is "Imagine if a round-trip flight from the US to Europe didn't cost $50,000,000, but only $500,000, unbelievable, right?"
Same ratios, but deeply different implications.
Today, the idea of setting up a continuously settled Mars colony - hell even a Moon colony - is unfeasibly expensive. It's ACHIEVABLE - we have the technology and the money - but it would cost an intolerable percentage of the GDP of the world to accomplish.
A 100x reduction in costs means that it becomes a fundable endeavour that countries like the US could still justify.
We're still talking about generations - maybe a century - away from someone being able to just pop over to Mars for a summer vacation, the way that a college student could to do today with an intercontinental flight.
> Many things we see in sci-fi, like lunar and Martian cities or orbital cruise ships, could soon become reality.
For a very generous definition of soon and for a highly implausible definition of what a "cruise ship" is - it'll never be as accessible to the average person as earth cruise ships. Not as long as you keep using rockets.
Regardless of reusability, there are realities of fixed FOSSIL FUEL costs associated with getting into gravity. They're not cheap, and they're not frivolous. If you want to be able get things into orbit as cheap as you're suggesting, you need to start investing in a space elevator, which noone is right now.
> Personally, I can’t wait to see a massive, kilometer-wide telescope in space
Cool, yeah, that's true, that becomes more available.
> or nestled in a crater on the Moon.
..why?
> We might finally figure out dark matter, dark energy, anti-gravity.
And the final cherry on the cake. Humanity becoming inter-planetary is important on a macro scale. And trying to go further and further into space will INCENTIVISE research into these concepts.
But in no way does getting to orbit cheaper make it easier to figure out any of these concepts. There's nothing we can do from Mars or on the way to Mars in terms of this science that we can't do from Earth.
> A 100x reduction in costs means that it becomes a fundable endeavour that countries like the US could still justify.
Don't forget the dynamics. Costs of all such projects drop further when early steps become affordable. Like, with 100x reduction on the sticker price, US might feel Mars colony is still too expensive a project, but 100x reduction on trying out some adjacent space tech may just be in range of NASA budget or some private interest. Steps get made, iterated on, making next steps cheaper and more likely to happen. Derisking compounds.
I do agree it'd still be a decades long project at least (with a settlement established early on; it's the tail end that will drag on).
>> or nestled in a crater on the Moon.
>..why?
Having some gravity and hard surface to build on simplifies engineering challenges, particularly on large scales, as in free space, tension becomes a big issue. And, perhaps more importantly, the Moon would shield the telescope from all the electromagnetic noise produced on Earth, and also by the Sun.
Consider ocean-going freight transportation: the container ships and the containers, the port facilities and the cranes. Now imagine that you were able to witness the very first round-trip sailing of such a container ship between two newly constructed still-experimental-and-heretofore-unproven ports.
That'd be pretty cool right? The dawn of a new era in global trade.
This is that, for space. (Booster as container ship, Orbital vehicle as container, launch tower as literal crane, launch complex as port)
No. The ports were just expanding on an existing idea. I live in a port city, a thousand years ago middle ages people with much smaller boats used this same area to travel much shorter distances with fewer goods, today it has those cranes and a railway and moves inter-modal containers which have travelled from across the world, but it's just the same idea.
Why is there a port here? Because of the unusual tidal pattern? Deep water? No. People. The other reasons are reasons to put the port here maybe in particular rather than a few miles in either direction, but the people are why there's a port. In 1024 there were thousands of people, today perhaps closer to half a million depending on how you count.
There are no people on Luna, and no people on Mars. Visiting these barren rocks is like going up Everest.
This damp rock is where our species was born and it's where it will die. It's not much, but its ours, and there's nothing like it within any plausible travel distance.
I’m with you. As landing the thing means nothing if you can’t get payloads to the destination. To get this thing to the moon would need like 20 refuelling flights to meet it on the way.
this just reads as very strange. "meet it on the way"? it's not like they can place these in an orbit that they can just pull up and stop to refuel like a highway gas station. the refueling "pod" would need to be moving at the same speed as the ship.
They took $3bn and where supposed to deliver a trip to the moon for that. Instead we got this video of a catch, which isn't even one of the listed milestones. Not great.
That $3B is milestone based, they don't get it until they deliver on the milestones. AFAICT, they've only hit a single milestone on the plan, and have received <$100M of the $3B to date.
I'm just going to choose peace today and say: the SpaceX engineers who've been at this forever and have shown that crazy stuff is actually possible are seriously amazing humans, and I do hope they are successful.
It is traditional to summon an Elon Musk Flamewar by implying even vaguely that he is successful. Elon Musk’s support for a candidate may have been pivotal in that candidate’s win today. This sort of thing is like bathing in gasoline next to a forest fire.
"Finally, adjusting the flight’s launch window to the late afternoon at Starbase will enable the ship to reenter over the Indian Ocean in daylight, providing better conditions for visual observations."
Finally, adjusting the flight’s launch window to the late afternoon at Starbase will enable the ship to reenter over the Indian Ocean in daylight, providing better conditions for visual observations.
Well, I started planning a road trip down Austin as soon as I saw this post. Crew of friends is coming together to watch! Thanks for posting. I'm so excited to witness this in person.
I’ve liked some of his other videos and made it in twenty minutes. He has three arguments: SpaceX is late and over budget on HLS, booster recapture is the easiest part of Starship’s technical risks and Starship is bad value for money.
On the first two he’s right. Starship was, per SpaceX’s proposal to NASA, supposed to be almost ready by now. It’s not. But neither is any other leg of Artemis, and there is no unforgivable delay in the timeline. (To the degree there are stupid delays, it’s because the FAA was playing water cop.)
Recapture is the easiest technical challenge of the programme. Partly because SpaceX already demonstrated most of the tech with Falcon 9. Partly because in-orbit refuelling is unprecedented. The lunar lander was one of the easiest parts of the Apollo programme, by similar measure—that doesn’t make it unimpressive.
The last—bad bang for the buck—is a value judgement. Do we want a heavy lift booster or more Mars rovers? If we want sustainable access to space, we need cheaper launch. If one doesn’t care about that, rovers are better spend, but at that point I can start arguing for feeding the hungry with those bucks.
I stopped watching when the criticism of Falcon 9’s price came up. Why should SpaceX, a private company, undercut itself? It’s already the cheapest (PSLV gives it a run for some orbits), most reliable and most frequent launch provider in the world. It makes sense to capture the delta as profit, in part to fund things like Starship. (There is also no inflation adjustment.)
In summary, the technical criticisms are accurate but out of context. The value judgement is subjective. If you don’t value cheap, frequent space launch of course Starship won’t make sense for any amount of money.
EDIT: Kept watching. The energy math on second-stage reëntry is okay as a first estimate. But we don’t have final numbers for anything. And there are a lot of unknowns, e.g. final dry weight, how much energy the heat tiles can store and dissipate, if transpiration cooling could work, how plasma could dissipate energy, whether compression heat could be redirected away from the craft, whether firing mid-descent could reduce heat, et cetera. We certainly don’t have enough data to reject it ex ante. And the second stage being unreadable doesn’t tank Starship, though it probably does Artemis.
> I stopped watching when the criticism of Falcon 9’s pricing came up. Why should SpaceX, a private company, undercut itself?

It makes sense for them to capture the delta as profit versus cut prices for the sake of it. (There is also no inflation adjusting done.)
Exactly, this is such an egregious claim that it proves there is no way this guy is arguing in good faith.
He says SpaceX only saves a tiny bit of money due to reuse because the retail price for F9 expendable is only a bit more than F9 reuseable.
That's like saying because the Big Mac costs $6.29 and the Big Mac combo costs $11.69, then therefore the drink and fries must cost McD's $5.40 to make. Just ridiculous.
I think he is probably right, if you think of Starship has a government-paid program to produce a moon lander. The Starship program has blown though the NASA money to produce the basic version (but not yet the additional money agreed for a more advanced design), but has yet to deliver on any of their contracted goals.
So by its own contract, it is just about to be over-budget, behind schedule, and thus a failed project. You can argue about the pandemic blowing their timing, but the fact remain.
But SpaceX is not treating the Starship as solely a moon landing project. They are using NASA's money presumably alongside other SpaceX and Starlink monies to produce a workhorse for a number of projects alongside the moon lander part. In the closer-term it will become the launch vehicle for Starlink (the next-gen of which is too big to be launched on other vehicles), and in the (very) long-term as a vehicle to Mars.
So SpaceX probably sees the Starship project as behind schedule (par for the course, both for space projects, and for Elon Musk), but not out-of-budget. Whether their customer, NASA, agrees with this outlook is something you would have to ask them.
So I think that the video's points are true, but lack some context.
They're working off the same license they used for test 5, so they basically have to exactly the same thing they did for test 5. They did manage to add this:
"An additional objective for this flight will be attempting an in-space burn using a single Raptor engine, further demonstrating the capabilities required to conduct a ship deorbit burn prior to orbital missions."
I think that's the last thing they need to do before they can actually launch satellites. I'm surprised there was no attempt on the last launch. Glad to see it this time. The improved Starlink constellation that Starship will enable is going to be awesome.
I think they will want to deal with heatshield first. As of now, it hasn't survived deorbiting.
SpaceX can launch satellites using Falcon9 and do it routinely. Starship needs to be developed and reach milestones, so they can get paid by NASA. Having a payload is a complication (unless it's a fun payload, remember the roadster car :D)
And they need to demo that the flaps hold up through re-entry with nominal, minimal damage, otherwise a permit for a plan involving re-entry over land (which is needed to catch the ship) would obviously not issue.
That's cool PR move. If they managed to light one then it's great success. If they don't people will think they just got unlucky. But if they tried to light all and only one would work or none, or one would work but some other blew up whole rocket it would look terrible. It's probably that last eventuality is something they want to prevent by trying to light just one.
It's not groundbreaking but it's important. They are demonstrating in orbit relight capability of the raptor engines. This is an absolute requirement before they can put it fully into orbit because losing control of a Starship in low earth orbit would be catastrophic.
Remote termination is something they can do in the early boost phase, when there is a defined hazard zone over a depopulated patch of ocean. It doesn't cause the rocket to disappear; its effect is to disable the engines, end uncontrolled acceleration, and break the booster apart into small pieces—all of which will still fall to the ground (ocean) as debris.
If you did this to a Starship in orbit, you'd likely have large chunks of steel reentering and reaching the ground intact.
If I understand you correctly: So you'd have to do it over unpopulated/depopulated areas, which is impossible to guarantee when you are zooming around the globe at very high speeds. Thanks for explaining.
If the object is already in orbit, the debris from an FTS activation would also mostly be left in orbit, which isn't great. They really need to demonstrate the ability to de-orbit the vehicle before putting into orbit.
Generally that isn't done for a vehicle in orbit, since the distribution of debris in orbits used by other spacecraft would be significant.
A Starship second stage stranded in orbit would be a problem because detonation would cause a bunch of orbital debris, but simply waiting for natural re-entry would result in an unpredictable landing location that could result in large debris reaching populated areas.
Reliable, controlled re-entry to a targeted location is very important for Starship to be an operational launch system.
It would work, all too well. Especially if the speed was just slightly suborbital. Rain of steel over a random spot (or, rather, a trace) on the Earth's surface. You may be lucky and that trace might cross a desolate ocean; or you may not be lucky, and some Asian megalopolis with 25 million people may be below.
Even at suborbital velocities, putting debris into the path of an existing satellite that is traveling at orbital velocity is enough to trigger a cascade.
No. An object in orbit colliding with anything threatens to create debris in orbit. Debris in orbit collides with other objects in orbit, creating debris in orbit. That's a cascade.
> Debris in orbit collides with other objects in orbit, creating debris in orbit. That's a cascade
For the same reason not every nucleus that fractures on neutron bombardment sustains chain reactions not every orbital configuration supports a Kessler cascade. In LEO, it’s virtually impossible: you get a nuisance, not SOL.
Note that Kessler posited his syndrome before we could computationally verify it. We can now. It’s not a real threat in the long term, and is more of an insurance question than existential issue for spaceflight in the medium term. It’s pertinent in the very short term, militarily, which is partly how we know it’s very difficult to trigger across even limited orbits.
LEO is the exact place you need to be careful. Higher orbits have more space and have fewer satellites overall so it's less of a concern.
Obviously not a problem for IFT6 since it's sub-orbital, but the original comment was about why we need a deorbit burn rather than just triggering the flight abort system.
> LEO is the exact place you need to be careful. Higher orbits have more space and have fewer satellites overall so it's less of a concern
No. In LEO orbits degrade in single-digit years at most. There is no known solution for rendering an orbit in LEO inaccessible with a Kessler cascade—the best you can do is blind an area with repeated ASAT fire.
In higher orbits debris last longer. That makes cascades possible, though again it only denies a limited area and requires almost active effort.
At least in LEO you need to keep expending DeltaV to keep stuff in orbit. Trace atmosphere slows everything down and would eventually clean LEO at 500km of relevant junk in about 25 years depending on altitude.
If you have debris in geostationary orbit, it will stay there basically forever whereas in low earth orbit it will burn up within a few years at worst.
Isla Blanca Park on South Padre Island is the best public spot you can watch from (IIRC it's 3 or 4 miles from the launch pad) and it's an amazing experience, highly recommended to anyone who's able to make it out.
I believe they clear out the launch site within a few kilometres so nobody gets hit by random concrete debris or just melt away, literally. The control centre is probably invitational.
But you can freely watch them live on Twitter. Just follow the official @SpaceX account.
Note that there will not be an official livestream on Youtube. Every time there are some people who fall for scammers pretending to be one and end up listening to an AI impersonation of Elon Musk try to sell them cryptocoins, missing the real launch.
If you must watch on youtube, NSF or Everyday Astronaut typically have good (unofficial) livestreams.
> Nearly four years ago, Apple co-founder Steve Wozniak actually sued YouTube over Bitcoin scam livestreams that were using his likeness. So, this has clearly been going on for quite a while now. And, unfortunately, it looks like these fake YouTube livestream schemes are going to continue on, at least for the foreseeable future.
I recently reported a bunch of the SpaceX ones that were running for long time. Nothing happened. I think Google/Alphabet is just happy with the extra ad views.
I'll often spend a little time while watching the flight-tests (usually with Tim Dodd / EverydayAstronaut) just doing a search on YouTube for 'spacex live' and usually report 15-20 each time. They are very easy to spot when you've seen a few of them. I'll usually get a report of a few being shut down later in the day, and more over the next couple of days.
But, yes, they should be easy for YT to detect & block automatically - it's frustrating they (and other scams) get to stay online so long.
The Everyday Astronaut was ahead of the SpaceX curated one for Flight 5. It had the weird effect of showing the outcome before the sound of the cheering crowd going crazy when the booster got caught by the chopsticks (which was also audible in the same stream).
Each streamer adds a delay to their stream. This means that any stream forwarded to you by another streamer is going to be delayed.
The delay was between SpaceX recording and uploading an event and Everyday astronaut decoding it at their mixing desk. Their own feeds from their cameras and microphones had less delay than the SpaceX stream did. Everyday astronaut then had another delay between when they encoded this result and you saw it.
If you had opened up the SpaceX stream directly you would have found it was ahead of the stream shown inside Everyday Astronaut.
EA and NSF have their own cameras so they aren't just republishing SpaceX's Twitter stream. But things definitely get out of sync when there are multiple layers of streaming.
Some of the views their cameras get are fantastic - and the tracking on the last flight test would quite possibly make NASA envious. Cameras on the beach and also just next to StarHopper are in harms way too, they've lost a couple of them. I'm not sure what the cost of repair was after a chunk of concrete from what used to be the pad took out the back of a car!
It's ironic given pre-acquisition under every Elon Musk tweet the top replies were always crypto scammers. Hopefully this time YouTube fix the impersonation stream but it was up for a long time during/after the last launch.
I assumed a large portion of YouTube/ Google management had been in a plane crash as that seemed the only plausible explanation for it to stay up as long and have as many viewers as it did. It really was stunning.
Suddenly, all those crypto-scam videos seem plausible now that Elon Musk pledged to give away $1 million daily to individuals who sign his political action committee’s petition supporting the First and Second Amendments.

A brilliant idea some startup accelerator in the EU can create a platform that conforms to EU laws. It can't be that hard, given that the UI hasn't changed much in a decade or more. I can already see it "Hacker news, but hosted in the EU with Swiss privacy and is GDPR compliant".
Seriously, who cares!
There are far more interesting stuff in space exploration than this flight tests of a giant boiler that's been going on for years now.
I find the starship news exciting, but given the incremental nature of starship development, it really isn't the most exciting stuff happening today with space exploration as there is all kinds of other cool stuff happening and being discovered.
Which is why I find it exciting and am stoked every time I see progress made.
Howevever, it's hard to view an announcement of the next launch with some minor additions to the experimental flight, as the most exciting space news today. Future launches, once they get the license updated, will he more exciting.
Please list them because right now it is a hugely costly project that has shown no significant capital advancement for society beyond propping up Elon Musk and a “someday the average man will walk on the moon” dream. If anything of capital gain comes from it, it will never actually benefit the financial bottom line of the middle and lower class.
Space based technology has massive impact on every day life. From GPS to weather prediction to communications, space infrastructure is critical to modern life.
Launch costs significantly reduce what we can build in space and what research we co do there. Decreasing launch costs makes our research funding more effective and reduces the capital costs and projected profit margins needed to build space based infrastructure.
SpaceX has already enabled significant economic growth and innovation with the launch cost reductions brought by the various falcon rockets and their reusability.
If Starship can accomplish it's reusability goals, an ever greater reduction of launch costs is possible. This would jump start an even bigger space industry boom than the one we are in today.
SpaceX just posted this video of the last test. It's one of the most inspiring things I've ever seen.
https://www.youtube.com/watch?v=hI9HQfCAw64
I find the experience of watching these SpaceX videos very emotional. There's something really inspiring both from an "exploring the universe" perspective and also just from the human side of all of the effort that went into them.
The first video that really got to me was when they landed multiple boosters. This one as well, especially seeing the rocket take off with every booster firing when compared with the first Starship launch when you could see that some failed to light. It's like watching your child take their first steps, and then seeing them win an Olympic medal for running. Just incredible stuff.
This kind of thing is why I got into engineering in the first place.
There's so much more to it than money.
For those of you who like dubstep, start the following video first https://www.youtube.com/watch?v=t2eBMuL0C2o then 3 seconds later start to watch the (muted) SpaceX video from OP's post and thank me later. ;-)
Especially the catch is awesome!
OK, that's downright creepy. Especially that the singing starts with the lyrics "holding on" at the exact moment the booster is caught by the chopsticks.
Nice, how did you find a music clip with such a good match across the whole video? Or are you saying you know that SpaceX media people were using that as test music when cutting theirs?
this was great. i hope someone just recuts video with exactly this soundtrack
I think it's a cool achievement, but for some perspective NASA first did a vertical rocket ship landing without chopsticks decades ago.
And the whole point of this thing was to do that on the moon, which is never going to happen at this rate.
And in 2002 a neuroscientist hooked a camera to a blind man's brain and he could see well enough to drive a car around an empty parking lot without running into things. And yet there are still many blind people.
Doing something cool once doesn't impact civilization. Doing it affordably at scale does. If Space X can do the chopstick landing reliably and integrate it into their operations, then that will be impactful - and change civilization.
https://en.wikipedia.org/wiki/William_H._Dobelle
Is the whole point of this thing to land the first stage on the moon, or just the Starship? My understanding is that it's just Starship, and the first stage will always return to Earth. I think one of us has a very confused understanding of the whole point of the thing.
They did? I've not heard of that, and a cursory search isn't finding anything. Got any more info on this, which rocket, etc? I'd love to learn about that.
I am assuming they are talking about this?

TLDR: DC-X (Delta Clipper X)
NASA Landed on the moon in the 60s with an abacus. SpaceX can’t get out of low Earth orbit.
I think it's a really responsible decision by SpaceX to not put their StarShip stage into a full orbit until they have demonstrated the ability to get it back out of orbit.
They should be applauded for this, along with their iterative approach.
Note that this next test will demonstrate re-light of the engine in space at micro-gravity. This is the demonstration needed prior to putting the StarShip in orbit. We'll probably see a full orbital test for the flight after this one.
They could have easily put previous tests into orbit - it's a fairly minor change to their existing regime and they have plenty of fuel to use.
Do you really believe that they “can’t” get out of low earth orbit, as opposed to “haven’t yet”??
Didn't SpaceX launch Europa Clipper to Jupiter a few weeks ago?
They also flung a Tesla Roadster off into a wayward journey around the Sun. Not nearly as impressive I know, but significantly more amusing.
Not into space things and while this is cool i wonder what the great significance of this is? I see lots signaling how great this is and it's lost on me.
Totally reasonable question. This is the first rocket ever that will (assuming further success) land in its entirety back on the launch pad, refuel, and go back to orbit the same day.
Imagine that every time an airliner landed its cockpit was destroyed and you had to build a new one. A fully reusable airplane would be a transformational improvement. That's the level of achievement we're talking about here.
> go again the same day.
That seems like a stretch. What is the actual turnaround time for Starship? fwiw the Shuttle had a lot of lofty promises of reusability that were technically true as long as you didn't consider how long the turnaround time was.
The shuttle boosters required rebuilding / refueling (which is solid rocket goop) and the fuel tank was completely lost and required rebuilding. The head shield tiles were extremely fragile on the shuttle.
It was never a fully reusable design, just more reusable than before.
SpaceX plans to have no parts that are lost each flight and is working to make the tiles mostly standardized and less sensitive to faults.
Are they going to replace all the tiles before it can relaunch? And what about the engine nozzles? They must be taking quite the beating.
No doubt SpaceX has very smart people working on this and I'm not an expert in material science, but I just find it hard to believe that same day turnaround could be possible. If true, that would really make us a confirmed space faring civilization. We could actually start colonizing Mars.
The heat tiles are reusable, just like the Shuttle's. They are basically just a material that insulates very well, instead of a traditional ablative heat shield that burns away. With the space shuttle they ended up spending a lot of time inspecting each tile for damage and replacing cracked tiles. SpaceX has a modern iteration of the same material, hopefully with fewer cracks.
Other factors that work in SpaceX's favor are 1) that most launches will be unmanned, meaning they can take bigger risks than the Space Shuttle program; 2) that the steel body of Starship can handle higher temperatures than the Space Shuttle's aluminum, so a compromised heat shield is more tolerable; 3) for now they have a secondary ablative heat shield below the tiles (that does have to be replaced when it gets used, but that should only happen when tiles fall off)
> what about the engine nozzles?
Falcon 9 has reflown in just over 4 hours [1]. (EDIT: Operational turnaround. Nozzles have been turned around allegedly without refurb in 3 weeks.)
[1] https://en.m.wikipedia.org/wiki/List_of_Falcon_9_and_Falcon_...
No, those were separate craft, on opposite sides of the country. It demonstrates an ability to manage multiple missions at once, but not rapid booster turnaround.
https://www.space.com/spacex-starlink-launch-doubleheader-ju...
They've since done two flights in about an hour with https://spaceflightnow.com/tag/starlink-9-5/ and https://spaceflightnow.com/tag/starlink-8-10/
I think the first-stage turnaround record is something like two weeks.
https://en.wikipedia.org/wiki/List_of_Falcon_9_first-stage_b...
> B1062 booster holds the record for fastest turnaround at 21 days. It launched on 8 April and again on 29 April 2022.
For context on JumpCrisscross's comment in this thread: the 4 hours is between two separate launches on two separate rockets. This is absolutely not refurbishing and launching the same rocket 4 hours apart.
Seems like the actual record for turning around the same booster is 21 days, which is still quite impressive.
https://www.teslarati.com/spacex-falcon-9-new-booster-turnar...
Some of SpaceX's first stages are getting close to the individual Shuttles' launch counts, with substantially less turnaround time and cost than Shuttle ever had.
Starship has work to do, but it's hard to argue they're not at least on the right path.
With the Falcon 9 they're already at over 100 launches this year. It's multiple rockets, but the turn around is pretty quick and getting quicker every year. They're designing starship from the start with same day turnaround in mind. I wouldn't bet against it I guess.
It's a good question. The hurdle to clear for same-day reuse will be the heat shield. SpaceX hasn't yet demonstrated that Starship can reenter the atmosphere and remain fully intact. Doing it while sustaining near zero wear on the heat shield will be even harder. But I think it is not impossible, and I don't know of any other obvious blockers for same day reuse.
Zero wear is not necessary. The tiles can be thicker than the minimum, and be reusable until they wear down to the minimum. Like the brake pads on your car.
They'll likely reuse the booster on the same day well before the starship portion. No heat shield on the booster. Some starships will likely stay in space for a long time before returning.
It's certainly looked fully intact when reaching ground.
When they manage to do the intended landing it should be pretty unharmed, but I'm sure it will take a while before same-day reuse is attempted.
One of the flaps burned through again. Not as bad as the first time. The hinge area seems like the hardest challenge.
It was a flap hinge that burnt through, not the flap. They have a solution for block 2 which we'll likely see in test 7 -- move the flap slightly further back so that the hinge isn't in direct flow.
Is this a bit of over engineering? How much is drag reduced during liftoff by having the flaps folded?
The reason the flaps move is to provide attitude and speed control during reentry. Like a skydiver spreading their arms and legs.
oh, you mean like actual flaps of pretty much any aircraft. doh! i was thinking it was like the folding of the wings for planes on an aircraft carrier. sometimes my brain, boy, i don't know
Even if they can reuse the booster, it would be huge.
For the Super Heavy booster, SpaceX is targeting a <1hr turnaround time. For the ship, it gets a bit more complex. Ships have to make complete orbits before returning, and generally they have to be loaded with cargo as well. Tanker Starships for lunar/Mars missions will probably have pretty quick turnaround given that fuel can be loaded on the pad; other ships will have significantly longer turnarounds.
The previous flight was October 13, 2024, so while I can't speak to every day, one month turnaround is a reality.
It's a completely different booster and ship that's flying.
And both are already outdated - flight seven (Ship 33) introduces a new generation of hardware. They're moving fast with these.
Is there such a need for a heavy launch rocket to launch routinely?
SpaceX already launches multiple times per month just to maintain Starlink. That will be much cheaper with Starship while enabling larger and more capable satellites. In fact, it's likely that one of the reasons SpaceX built Starlink is to create their own customer (and spur competitors) to plausibly use a significant fraction of Starship's capabilities. None existed at the time.
In the near term the biggest reason to do multiple launches in a day will be orbital refueling. This is required for sending much, much larger payloads to the Moon and Mars. It will require on the order of 10 launches to fuel up one moon lander in orbit, and obviously doing that as quickly as possible will be beneficial. NASA has already committed to this plan for Artemis.
> It will require on the order of 10 launches to fuel up one moon lander in orbit
Require, or just make comfortable? Saturn V had the lift capacity of "only" a couple of Falcon Heavies, but was enough to carry astronauts, a car, a lunar lander with enough fuel to take off, and a command module.
We're not trying to do Apollo again. That would be easier, but we want to build a base this time. For that we need to send a lot more mass and it needs a lot more fuel.
Require. I answered that in this same subtopic.
It's a mandate for the next Artemis Mission. [1]
The HLS (Spaceship) will need many refuels at orbit in order to get to the Moon and back. That means at least a dozen of fully-loaded Heavy launches to LEO just so each one of them can load a bit of fuel into HLS. The fuel in orbit can't sit idle for too long, or it deteriorates; I haven't found a limit on days for that, but a week-long launch window is considered a dealbreaker, we're talking a dozen Heavy launches in a week.
It's either a short launch window, or at least 6 Starships built and launched twice in ~10 days. Don't count out on SpaceX building 12 Heavy Starships just for that Artemis mission.
[1] https://en.wikipedia.org/wiki/Artemis_III
If satellites don't have to worry as much about weight constraints they can be made cheaper and quicker. Space missions can become more routine.
If we want to establish long term bases on the Moon or Mars then yes, you need not only to send crew and habitation modules but ongoing supplies and equipment.
Other use cases include launching and maintaining satellite constellations (Starling / Starshield), and launching singular large payloads like space telescopes.
Even for smaller payloads, having both the first and second stages be reusable will reduce launch costs.
Yes, obviously.
It takes a heavy launch rocket to launch heavier things into space or missions, refueling, and to goto other planets.
Yes, to do anything at all in the rest of the universe.
We are insatiably curious explorers. The cosmos calls to us. Many are willing to do anything they can to answer that call.
Needs tend to develop once the means are there.
200 years ago, there was no need to use electricity. 100 years ago, there was no need to use a programming language. 30 years ago, there was no need for gigabit wireless Internet.
> Needs tend to develop once the means are there.
Counterexample: space stations. We've had small manned space stations for decades now, but no real application for them. They're national prestige items only.
Or perhaps earlier and closer to the heart of USA's citizens, 300 years ago, there was no need for rail lines and trains.
Nobody will ever need more than 640k of RAM.
I think the economics of space are are much more likely to be transformed by something like https://www.longshotspace.com/. Rockets are complex, still costly, and polluting.
The problem with space guns is you can't just yeet rocks into orbit. Any orbit that starts at the surface returns to the surface. So you still need a disposable rocket and avionics and fuel in every payload to change the orbit once out of the atmosphere. Only now the rocket needs to survive being literally shot out of a gun and then traveling at orbital velocity in atmosphere. That puts a pretty high floor on the cost per shot.
If you want to look at someone that is further along on a concept like this you can look at SpinLaunch. Exactly what it sounds like with a gigantic centrifuge to spin and throw things really fast. But they are still throwing a small two-stage rocket.
https://www.spinlaunch.com/orbital
I think a reusable in-orbit tug which rendezvous with payloads is the play here. The tug would refuel from the gun-launched payloads.
Plus, your payload needs to be gun compatible. Not gonna put people in there.
Well, in WW2 we did manage to put working radar in artillery shells.
Space is for robots.
He's already spent the $3bn funding that was supposed to deliver the rocket to the moon and back.
That's just straight up not true. The $3bn were never meant to fund the entire project in the way you imply.
The big thing is that it dramatically reduces the cost of shipping things into space. Previously it was difficult to ship anything much larger than a compact car in to orbit. Now you can ship half of a basketball court into orbit, including all the vertical space.
Until very very recently the roughly bus sized ISS modules were the largest habitable spaces we could ship to orbit (although Skylab in the 70s were basically repurposed Saturn V fuel tanks and also big) so now it's possible/probable we can ship 20 people to space, and have moderately comfortable accommodations for them.
We can also ship mining equipment and substancially more supplies to the moon. Or mars. We went from using pack goats to 18 wheelers to ship stuff in space. The pack goat can ship a handful of hand made silk scarves and Faberge eggs over the Himalayas, but the 18 wheeler can deliver everything from socks and tshirts to cell phones and big screen tvs and trucks and lawn mowers. This really opens up space to more than the highest, most bleeding edge science and we might actually see more than 100 humans in space at the same time, in our lifetimes.
Literally anything but the metric system, huh? ;)
I applaud GP's effort at also avoiding shipping cliches like Olympic-size swimming pools.
Well, basketball courts have a ~12m diameter 3-point line, and the inside of a starship is ~9m. Swimming pools are mostly rectangular from the outside observer's perspective.
If you go to space, 90% of the cost is the rocket (depending on your accounting). If rockets can be made reusable, then you can drop costs by 90%, to first order. Cheaper rockets means cheaper satellites for internet and sensors and stuff.
Also, as mass to orbit gets cheaper you can build your payload more cheaply. Many compromises in complexity and material cost are made to minimize payload mass - we'll be able to launch cheap and heavy satellites and probes into orbit instead.
Cheaper rockets also mean cheaper payload in that the payloads don't have to be engineered to such high standards of reliability.
>(depending on your accounting).
some of the best weasel words ever laid to print. Enron accounting vs PWC vs your mom using Quickbooks for her side hustle type of depending?
It's a rocket in the same ballpark as the Saturn V but where the two stages can both be recovered and re-used.
SpaceX has demonstrated being able to fly the same rocket stage dozens of times with minimal refurbishment with their Falcon 9 family of rockets, but they still have to build and discard the second stage of the Falcon 9 for each launch.
Starship scales that up in magnitude and adds second-stage reusability.
This article [0] is a pretty good explainer for why Starship is such a big deal
[0] https://caseyhandmer.wordpress.com/2021/10/28/starship-is-st...
Brilliant article, and I neglected to bookmark it earlier, thank you.
This is a great resource for why Starship is groundbreaking. So much so, it’s not even really comprehensive to the existing space-industrial complex.
https://caseyhandmer.wordpress.com/2021/10/28/starship-is-st...
Price decreases significantly when you can reuse. This rocket is the same size as the ones that brought the Apollo missions to the moon, but will cost significantly less because they don't have to build one every time they launch it.
Imagine if a round-trip flight from the US to Europe didn’t cost $500, but only $5, unbelievable, right? This is exactly what Starship will do to space travel. Many things we see in sci-fi, like lunar and Martian cities or orbital cruise ships, could soon become reality.
Personally, I can’t wait to see a massive, kilometer-wide telescope in space or nestled in a crater on the Moon. We might finally figure out dark matter, dark energy, anti-gravity.
See this is the kind of thing that's not helpful.
It's just an outlandish overly optimistic mishmash of different concepts.
Let's start with your analogy:
> Imagine if a round-trip flight from the US to Europe didn’t cost $500, but only $5, unbelievable, right?
If you mean to use this to explain that what today costs X will in the future cost 0.01X, you're probably right.
But a more accurate analogy is "Imagine if a round-trip flight from the US to Europe didn't cost $50,000,000, but only $500,000, unbelievable, right?"
Same ratios, but deeply different implications.
Today, the idea of setting up a continuously settled Mars colony - hell even a Moon colony - is unfeasibly expensive. It's ACHIEVABLE - we have the technology and the money - but it would cost an intolerable percentage of the GDP of the world to accomplish.
A 100x reduction in costs means that it becomes a fundable endeavour that countries like the US could still justify.
We're still talking about generations - maybe a century - away from someone being able to just pop over to Mars for a summer vacation, the way that a college student could to do today with an intercontinental flight.
> Many things we see in sci-fi, like lunar and Martian cities or orbital cruise ships, could soon become reality.
For a very generous definition of soon and for a highly implausible definition of what a "cruise ship" is - it'll never be as accessible to the average person as earth cruise ships. Not as long as you keep using rockets.
Regardless of reusability, there are realities of fixed FOSSIL FUEL costs associated with getting into gravity. They're not cheap, and they're not frivolous. If you want to be able get things into orbit as cheap as you're suggesting, you need to start investing in a space elevator, which noone is right now.
> Personally, I can’t wait to see a massive, kilometer-wide telescope in space
Cool, yeah, that's true, that becomes more available.
> or nestled in a crater on the Moon.
..why?
> We might finally figure out dark matter, dark energy, anti-gravity.
And the final cherry on the cake. Humanity becoming inter-planetary is important on a macro scale. And trying to go further and further into space will INCENTIVISE research into these concepts.
But in no way does getting to orbit cheaper make it easier to figure out any of these concepts. There's nothing we can do from Mars or on the way to Mars in terms of this science that we can't do from Earth.
> A 100x reduction in costs means that it becomes a fundable endeavour that countries like the US could still justify.
Don't forget the dynamics. Costs of all such projects drop further when early steps become affordable. Like, with 100x reduction on the sticker price, US might feel Mars colony is still too expensive a project, but 100x reduction on trying out some adjacent space tech may just be in range of NASA budget or some private interest. Steps get made, iterated on, making next steps cheaper and more likely to happen. Derisking compounds.
I do agree it'd still be a decades long project at least (with a settlement established early on; it's the tail end that will drag on).
>> or nestled in a crater on the Moon.
>..why?
Having some gravity and hard surface to build on simplifies engineering challenges, particularly on large scales, as in free space, tension becomes a big issue. And, perhaps more importantly, the Moon would shield the telescope from all the electromagnetic noise produced on Earth, and also by the Sun.
Consider ocean-going freight transportation: the container ships and the containers, the port facilities and the cranes. Now imagine that you were able to witness the very first round-trip sailing of such a container ship between two newly constructed still-experimental-and-heretofore-unproven ports.
That'd be pretty cool right? The dawn of a new era in global trade.
This is that, for space. (Booster as container ship, Orbital vehicle as container, launch tower as literal crane, launch complex as port)
No. The ports were just expanding on an existing idea. I live in a port city, a thousand years ago middle ages people with much smaller boats used this same area to travel much shorter distances with fewer goods, today it has those cranes and a railway and moves inter-modal containers which have travelled from across the world, but it's just the same idea.
Why is there a port here? Because of the unusual tidal pattern? Deep water? No. People. The other reasons are reasons to put the port here maybe in particular rather than a few miles in either direction, but the people are why there's a port. In 1024 there were thousands of people, today perhaps closer to half a million depending on how you count.
There are no people on Luna, and no people on Mars. Visiting these barren rocks is like going up Everest.
This damp rock is where our species was born and it's where it will die. It's not much, but its ours, and there's nothing like it within any plausible travel distance.
Rockets that are easily reusable make spaceflight a lot more logistically feasible, which should translate to a massive drop in costs.
We are going to see massively increased space activity of all sorts. It is almost impossible to predict all consequences thereof.
I’m with you. As landing the thing means nothing if you can’t get payloads to the destination. To get this thing to the moon would need like 20 refuelling flights to meet it on the way.
this just reads as very strange. "meet it on the way"? it's not like they can place these in an orbit that they can just pull up and stop to refuel like a highway gas station. the refueling "pod" would need to be moving at the same speed as the ship.
They took $3bn and where supposed to deliver a trip to the moon for that. Instead we got this video of a catch, which isn't even one of the listed milestones. Not great.
That $3B is milestone based, they don't get it until they deliver on the milestones. AFAICT, they've only hit a single milestone on the plan, and have received <$100M of the $3B to date.
I'm just going to choose peace today and say: the SpaceX engineers who've been at this forever and have shown that crazy stuff is actually possible are seriously amazing humans, and I do hope they are successful.
>I'm just going to choose peace today
As an alternative to what? I don't understand how the first part of the comment is connected to the rest.
I think they’re trying to maintain focus on the engineering rather than the politics surrounding Musk at the moment.
The news is about SpaceX sharing the launch date for the 6th Starship test flight. Musk is not even mentioned in the announcement.
Yet people cannot help themselves.
Musk owns, runs, and is the public face of SpaceX, he is automatically germane to any discussion of it.
He choose not to mention the top 20 Diablo IV player.
It is traditional to summon an Elon Musk Flamewar by implying even vaguely that he is successful. Elon Musk’s support for a candidate may have been pivotal in that candidate’s win today. This sort of thing is like bathing in gasoline next to a forest fire.
Because of what happened today...
Democracy?
Idiocracy
Can we stop saying "humans" and start saying "people" again? Are you from another species?
> the 30-minute launch window will open at 4:00 p.m. CT
Is that correct? They're launching in the afternoon this time?
"Finally, adjusting the flight’s launch window to the late afternoon at Starbase will enable the ship to reenter over the Indian Ocean in daylight, providing better conditions for visual observations."
From the linked article.
It's explained further down the page that this launch time will facilitate the Indian Ocean landing in sunlight, for improved visual capture of that.
For anyone else who was confused and thought this was happening today. It's actually in 12 days:
The sixth flight test of Starship is targeted to launch as early as Monday, November 18.
The 30-minute launch window will open at 4:00 p.m. CT
They call out later launch on the page linked
Finally, adjusting the flight’s launch window to the late afternoon at Starbase will enable the ship to reenter over the Indian Ocean in daylight, providing better conditions for visual observations.
Well, I started planning a road trip down Austin as soon as I saw this post. Crew of friends is coming together to watch! Thanks for posting. I'm so excited to witness this in person.
Can someone give me sources for how to debunk this? https://youtu.be/75a49S4RTRU?si=dcGFgcIWNz3nDwxw
For me, it’s compelling but I’m no expert. Anyone got any background that can prove this guy is wrong?
I’ve liked some of his other videos and made it in twenty minutes. He has three arguments: SpaceX is late and over budget on HLS, booster recapture is the easiest part of Starship’s technical risks and Starship is bad value for money.
On the first two he’s right. Starship was, per SpaceX’s proposal to NASA, supposed to be almost ready by now. It’s not. But neither is any other leg of Artemis, and there is no unforgivable delay in the timeline. (To the degree there are stupid delays, it’s because the FAA was playing water cop.)
Recapture is the easiest technical challenge of the programme. Partly because SpaceX already demonstrated most of the tech with Falcon 9. Partly because in-orbit refuelling is unprecedented. The lunar lander was one of the easiest parts of the Apollo programme, by similar measure—that doesn’t make it unimpressive.
The last—bad bang for the buck—is a value judgement. Do we want a heavy lift booster or more Mars rovers? If we want sustainable access to space, we need cheaper launch. If one doesn’t care about that, rovers are better spend, but at that point I can start arguing for feeding the hungry with those bucks.
I stopped watching when the criticism of Falcon 9’s price came up. Why should SpaceX, a private company, undercut itself? It’s already the cheapest (PSLV gives it a run for some orbits), most reliable and most frequent launch provider in the world. It makes sense to capture the delta as profit, in part to fund things like Starship. (There is also no inflation adjustment.)
In summary, the technical criticisms are accurate but out of context. The value judgement is subjective. If you don’t value cheap, frequent space launch of course Starship won’t make sense for any amount of money.
EDIT: Kept watching. The energy math on second-stage reëntry is okay as a first estimate. But we don’t have final numbers for anything. And there are a lot of unknowns, e.g. final dry weight, how much energy the heat tiles can store and dissipate, if transpiration cooling could work, how plasma could dissipate energy, whether compression heat could be redirected away from the craft, whether firing mid-descent could reduce heat, et cetera. We certainly don’t have enough data to reject it ex ante. And the second stage being unreadable doesn’t tank Starship, though it probably does Artemis.
> I stopped watching when the criticism of Falcon 9’s pricing came up. Why should SpaceX, a private company, undercut itself? It’s already the cheapest (relative to mass; PSLV gives it a run for some orbits), most reliable and most frequent launch provider in the world. It makes sense for them to capture the delta as profit versus cut prices for the sake of it. (There is also no inflation adjusting done.)
Exactly, this is such an egregious claim that it proves there is no way this guy is arguing in good faith.
He says SpaceX only saves a tiny bit of money due to reuse because the retail price for F9 expendable is only a bit more than F9 reuseable.
That's like saying because the Big Mac costs $6.29 and the Big Mac combo costs $11.69, then therefore the drink and fries must cost McD's $5.40 to make. Just ridiculous.
I think he is probably right, if you think of Starship has a government-paid program to produce a moon lander. The Starship program has blown though the NASA money to produce the basic version (but not yet the additional money agreed for a more advanced design), but has yet to deliver on any of their contracted goals.
So by its own contract, it is just about to be over-budget, behind schedule, and thus a failed project. You can argue about the pandemic blowing their timing, but the fact remain.
But SpaceX is not treating the Starship as solely a moon landing project. They are using NASA's money presumably alongside other SpaceX and Starlink monies to produce a workhorse for a number of projects alongside the moon lander part. In the closer-term it will become the launch vehicle for Starlink (the next-gen of which is too big to be launched on other vehicles), and in the (very) long-term as a vehicle to Mars.
So SpaceX probably sees the Starship project as behind schedule (par for the course, both for space projects, and for Elon Musk), but not out-of-budget. Whether their customer, NASA, agrees with this outlook is something you would have to ask them.
So I think that the video's points are true, but lack some context.
You're ignoring that this is a fixed-price contract. It will never be over-budget from NASA's perspective.
Also, for a project like HLS, you don't fail until you stop trying (or get someone killed, but SpaceX has been pretty good at not killing astronauts).
TF seems to have an axe to grind with all things Musk.
What did he say that was wrong?
TF has had terminal Musk derangement syndrome for a while now. You can safely ignore him.
Science fiction becomes reality!
Love the diamonds in the exhaust!
Last times catch was incredible, anything groundbreaking being attempted this time?
They're working off the same license they used for test 5, so they basically have to exactly the same thing they did for test 5. They did manage to add this:
"An additional objective for this flight will be attempting an in-space burn using a single Raptor engine, further demonstrating the capabilities required to conduct a ship deorbit burn prior to orbital missions."
I think that's the last thing they need to do before they can actually launch satellites. I'm surprised there was no attempt on the last launch. Glad to see it this time. The improved Starlink constellation that Starship will enable is going to be awesome.
I think they will want to deal with heatshield first. As of now, it hasn't survived deorbiting.
SpaceX can launch satellites using Falcon9 and do it routinely. Starship needs to be developed and reach milestones, so they can get paid by NASA. Having a payload is a complication (unless it's a fun payload, remember the roadster car :D)
That and flap sturdiness, if they want to be able to re-enter over land so they can catch the ship.
It's not required for launching satellites. But yeah, they need to figure out the heat shield for the flap hinges before they can recover the ship.
And they need to demo that the flaps hold up through re-entry with nominal, minimal damage, otherwise a permit for a plan involving re-entry over land (which is needed to catch the ship) would obviously not issue.
They've addressed that in Block 2. Test 6 still flies block 1, so we won't see any substantive improvements on that until test 7.
That's cool PR move. If they managed to light one then it's great success. If they don't people will think they just got unlucky. But if they tried to light all and only one would work or none, or one would work but some other blew up whole rocket it would look terrible. It's probably that last eventuality is something they want to prevent by trying to light just one.
It's not groundbreaking but it's important. They are demonstrating in orbit relight capability of the raptor engines. This is an absolute requirement before they can put it fully into orbit because losing control of a Starship in low earth orbit would be catastrophic.
> because losing control of a Starship in low earth orbit would be catastrophic
Why? Remote detonation wouldn't work in that case?
Remote termination is something they can do in the early boost phase, when there is a defined hazard zone over a depopulated patch of ocean. It doesn't cause the rocket to disappear; its effect is to disable the engines, end uncontrolled acceleration, and break the booster apart into small pieces—all of which will still fall to the ground (ocean) as debris.
If you did this to a Starship in orbit, you'd likely have large chunks of steel reentering and reaching the ground intact.
If I understand you correctly: So you'd have to do it over unpopulated/depopulated areas, which is impossible to guarantee when you are zooming around the globe at very high speeds. Thanks for explaining.
If the object is already in orbit, the debris from an FTS activation would also mostly be left in orbit, which isn't great. They really need to demonstrate the ability to de-orbit the vehicle before putting into orbit.
Generally that isn't done for a vehicle in orbit, since the distribution of debris in orbits used by other spacecraft would be significant.
A Starship second stage stranded in orbit would be a problem because detonation would cause a bunch of orbital debris, but simply waiting for natural re-entry would result in an unpredictable landing location that could result in large debris reaching populated areas.
Reliable, controlled re-entry to a targeted location is very important for Starship to be an operational launch system.
Detonation in orbit would cause garbage in orbit that could destroy many satellites. It is absolutely not permitted.
It would work, all too well. Especially if the speed was just slightly suborbital. Rain of steel over a random spot (or, rather, a trace) on the Earth's surface. You may be lucky and that trace might cross a desolate ocean; or you may not be lucky, and some Asian megalopolis with 25 million people may be below.
Detonating something in orbit could trigger Kessler's Syndrome.
> Detonating something in orbit could trigger Kessler's Syndrome
Unlikely in general, no at LEO and definitely not at the suborbital velocities IFT-6 contemplates.
Even at suborbital velocities, putting debris into the path of an existing satellite that is traveling at orbital velocity is enough to trigger a cascade.
Collision, yes, cascade no.
No. An object in orbit colliding with anything threatens to create debris in orbit. Debris in orbit collides with other objects in orbit, creating debris in orbit. That's a cascade.
No. Orbital mechanically, no.
> Debris in orbit collides with other objects in orbit, creating debris in orbit. That's a cascade
For the same reason not every nucleus that fractures on neutron bombardment sustains chain reactions not every orbital configuration supports a Kessler cascade. In LEO, it’s virtually impossible: you get a nuisance, not SOL.
Note that Kessler posited his syndrome before we could computationally verify it. We can now. It’s not a real threat in the long term, and is more of an insurance question than existential issue for spaceflight in the medium term. It’s pertinent in the very short term, militarily, which is partly how we know it’s very difficult to trigger across even limited orbits.
LEO is the exact place you need to be careful. Higher orbits have more space and have fewer satellites overall so it's less of a concern.
Obviously not a problem for IFT6 since it's sub-orbital, but the original comment was about why we need a deorbit burn rather than just triggering the flight abort system.
> LEO is the exact place you need to be careful. Higher orbits have more space and have fewer satellites overall so it's less of a concern
No. In LEO orbits degrade in single-digit years at most. There is no known solution for rendering an orbit in LEO inaccessible with a Kessler cascade—the best you can do is blind an area with repeated ASAT fire.
In higher orbits debris last longer. That makes cascades possible, though again it only denies a limited area and requires almost active effort.
At least in LEO you need to keep expending DeltaV to keep stuff in orbit. Trace atmosphere slows everything down and would eventually clean LEO at 500km of relevant junk in about 25 years depending on altitude.

but lower orbits also decay quickly.
If you have debris in geostationary orbit, it will stay there basically forever whereas in low earth orbit it will burn up within a few years at worst.
Does anyone know how to witness these launch events live? Is it open to the public or only SpaceX employees + friends & family?
Isla Blanca Park on South Padre Island is the best public spot you can watch from (IIRC it's 3 or 4 miles from the launch pad) and it's an amazing experience, highly recommended to anyone who's able to make it out.
I believe they clear out the launch site within a few kilometres so nobody gets hit by random concrete debris or just melt away, literally. The control centre is probably invitational.
But you can freely watch them live on Twitter. Just follow the official @SpaceX account.
Yes it's open to everyone. South Padre Island would be your best bet.
So is the Gulf, except in the areas closed by the notam.
I imagine SpaceX is on for some pretty juicy government contracts now!
Yes, considering they're achieving far better results at much lower cost than the SLS and other launch providers.
That remains to be seen. It ain't finished yet!
They're already the best and cheapest launch provider with Falcon 9.
Falcon 9 and SLS are not in the same class.
Shouldn't they be? Boeing, Lockheed and Blue Origin are welcome to compete and do just as well.
You mean after the Boeing debacle?
They already have lion's share of NASA and Space Force govt contracts.
Cargo runs to ISS, bringing astronauts to and from ISS, NROL missions, scientific missions (like Europa Clipper recently).
Sure they do, but the government could choose to spend more or less on space, couldn't they?
Note that there will not be an official livestream on Youtube. Every time there are some people who fall for scammers pretending to be one and end up listening to an AI impersonation of Elon Musk try to sell them cryptocoins, missing the real launch.
If you must watch on youtube, NSF or Everyday Astronaut typically have good (unofficial) livestreams.
Considering how long those videos have been allowed on YouTube, you have to wonder...
https://mashable.com/article/fake-elon-musk-crypto-scam-yout...
> Nearly four years ago, Apple co-founder Steve Wozniak actually sued YouTube over Bitcoin scam livestreams that were using his likeness. So, this has clearly been going on for quite a while now. And, unfortunately, it looks like these fake YouTube livestream schemes are going to continue on, at least for the foreseeable future.
I recently reported a bunch of the SpaceX ones that were running for long time. Nothing happened. I think Google/Alphabet is just happy with the extra ad views.
This aspect needs regulation.
I'll often spend a little time while watching the flight-tests (usually with Tim Dodd / EverydayAstronaut) just doing a search on YouTube for 'spacex live' and usually report 15-20 each time. They are very easy to spot when you've seen a few of them. I'll usually get a report of a few being shut down later in the day, and more over the next couple of days.
But, yes, they should be easy for YT to detect & block automatically - it's frustrating they (and other scams) get to stay online so long.
Perhaps your account has more Youtube XP.
> But, yes, they should be easy for YT to detect & block automatically - it's frustrating they (and other scams) get to stay online so long.
It's the Google way. It's impossible until it suddenly isn't.
Break up this monster company and regulate the resulting companies until they behave.
The Everyday Astronaut was ahead of the SpaceX curated one for Flight 5. It had the weird effect of showing the outcome before the sound of the cheering crowd going crazy when the booster got caught by the chopsticks (which was also audible in the same stream).
Each streamer adds a delay to their stream. This means that any stream forwarded to you by another streamer is going to be delayed.
The delay was between SpaceX recording and uploading an event and Everyday astronaut decoding it at their mixing desk. Their own feeds from their cameras and microphones had less delay than the SpaceX stream did. Everyday astronaut then had another delay between when they encoded this result and you saw it.
If you had opened up the SpaceX stream directly you would have found it was ahead of the stream shown inside Everyday Astronaut.
BTW I was also watching EA's stream.
EA and NSF have their own cameras so they aren't just republishing SpaceX's Twitter stream. But things definitely get out of sync when there are multiple layers of streaming.
Some of the views their cameras get are fantastic - and the tracking on the last flight test would quite possibly make NASA envious. Cameras on the beach and also just next to StarHopper are in harms way too, they've lost a couple of them. I'm not sure what the cost of repair was after a chunk of concrete from what used to be the pad took out the back of a car!
Thank you for the clarification. It's delays all the way down. :)
I was cycling between the "official" stream and EA to try and catch the most-live and I found EA was a couple seconds ahead.
It's ironic given pre-acquisition under every Elon Musk tweet the top replies were always crypto scammers. Hopefully this time YouTube fix the impersonation stream but it was up for a long time during/after the last launch.
I assumed a large portion of YouTube/ Google management had been in a plane crash as that seemed the only plausible explanation for it to stay up as long and have as many viewers as it did. It really was stunning.
Nah, they are just ignoring the damaging effects on individuals and cashing in the ad money.
Suddenly, all those crypto-scam videos seem plausible now that Elon Musk pledged to give away $1 million daily to individuals who sign his political action committee’s petition supporting the First and Second Amendments.
Thread devolved into petty politics quicker than expected.
I tried to search faq how to block people but couldn't find any info. How do I do that?
If it's not possible, I'm pretty sure this site is breaking the EU social media laws.
The site doesn't need to follow the laws of every country on earth. If they had paid advertisers from EU it would be different.
I use uBlock Origin cosmetic filters for blocking trolls on here. Something like:
HN is a pretty high trust site, I'd hope the community is still mature enough to self-moderate. Then again I was here when Terry would post his (admittedly) entertaining rants, the epic Michael O'Church essays, and flamewars between idlewords and pg. Maybe it always allowed for a little bit of funposting, in moderation.
There's no "block user" requirement in the EU DSA.
Which EU laws do you think mandate a 'block' feaure on HN?
That rule doesn't exist.
A brilliant idea some startup accelerator in the EU can create a platform that conforms to EU laws. It can't be that hard, given that the UI hasn't changed much in a decade or more. I can already see it "Hacker news, but hosted in the EU with Swiss privacy and is GDPR compliant".
Seriously, who cares! There are far more interesting stuff in space exploration than this flight tests of a giant boiler that's been going on for years now.
You must be joking
Nope, not joking at all.
I find the starship news exciting, but given the incremental nature of starship development, it really isn't the most exciting stuff happening today with space exploration as there is all kinds of other cool stuff happening and being discovered.
One example off the top of my head:
https://earthsky.org/space/final-parker-solar-probe-flyby-of...
Starship is an enabling technology. We can easily imagine the things it will make possible.
Which is why I find it exciting and am stoked every time I see progress made.
Howevever, it's hard to view an announcement of the next launch with some minor additions to the experimental flight, as the most exciting space news today. Future launches, once they get the license updated, will he more exciting.
Please list them because right now it is a hugely costly project that has shown no significant capital advancement for society beyond propping up Elon Musk and a “someday the average man will walk on the moon” dream. If anything of capital gain comes from it, it will never actually benefit the financial bottom line of the middle and lower class.
Space based technology has massive impact on every day life. From GPS to weather prediction to communications, space infrastructure is critical to modern life.
Launch costs significantly reduce what we can build in space and what research we co do there. Decreasing launch costs makes our research funding more effective and reduces the capital costs and projected profit margins needed to build space based infrastructure.
SpaceX has already enabled significant economic growth and innovation with the launch cost reductions brought by the various falcon rockets and their reusability.
If Starship can accomplish it's reusability goals, an ever greater reduction of launch costs is possible. This would jump start an even bigger space industry boom than the one we are in today.
