It's similar to last time if you saw that, the first stage will come back towards the launch site and they will try to catch it with the landing tower chopsticks, while the second stage does a soft landing in the ocean after going halfway around the earth.
As far as new stuff, they are trying to deploy some simulated satellites from the second stage and will try to relight one of the engines.
Yes, about 2m longer. Also some modifications to the heat shield, including testing new types of heat shield tiles. Also non-structural versions of new catch pins to see how they perform on reentry
Edit: also, they are reflying one of the raptor engines that was on the previous flight (Engine 314, because pi).
Preparing to launch 4:37pm CT (~45mins after this comment)
First 10mins watching gets you to space with engine shutdown.
38mins after launch engine turns back on. 10mins after that reentry starts. 1:06 after launch is the landing.
I think that covers it.
Space X has failed after 3 billion US tax payer dollars to take a banana into low earth orbit. Needless to say we aren't going to Mars last year watching a woman in a long dress floating in the cargo bay behind a curtain of glass windows playing a violin for entertaining the dozens of astronaut's which don't have space for food, water, belongings or life support.

Literally just lofted some satellites.
I absolutely cannot relate to the HN excitement over rockets. What is the point? What are we going to do with them? It feels like half religion half misplaced techno-positivism.
(Also a person who actively platforms outspoken neo-nazis runs the company that is launching them)
The reason is pretty simple. The technology you are using right now, was created with knowledge that was obtained in orbit.
If you use GPS, you are inherently reliant on satellites, delivered with rockets.
Some of our resource shortages can be covered via resource acquisition in space.
Pushing the space frontier, is far more interesting and important, than mobile phone screen size, or fidelity.
It opens an entire new area to the sciences.
Also big explody tube warms the cockles of my heart.
Many of the techie people on HN undoubtedly dreamed of building and flying rockets at some point in their tweens / teens till the harsh realities of the material world took over. So they are vicariously living childhood dreams... Just like many "normal" people live theirs by following sports teams or celebrities. To each their own :-)
Rockets are good. They give us hope that one day we ll explore the stars. Let people enjoy the small wins.
Also, the (IMHO false) hope that we can escape the planet after we destroy it. Well, maybe the few richest will be able to do that ...
Yeah there is a huge amount of rationalizing how the debris aren’t a problem. Everyone is certain it will burn up before hitting the ground, and if it doesn’t, it will land somewhere that doesn’t matter… but I don’t think anyone knows that for sure?
Rockets are cool but it’s everyone’s planet, if this continues to make a huge mess, do us regular earth citizens have recourse?
@elonmusk Preliminary indication is that we had an oxygen/fuel leak in the cavity above the ship engine firewall that was large enough to build pressure in excess of the vent capacity.
Apart from obviously double-checking for leaks, we will add fire suppression to that volume and probably increase vent area. Nothing so far suggests pushing next launch past next month.
Except for that whole second stage and payload part.
Actually I thought there would be less risk with the second stage changes, significant as they were, than the second catch. (Maybe there was less risk, of course, and the dice just didn't roll that way).
Extremely shallow take on what is undoubtedly the rise of America's next great space era
> They burned billions of public funds, literally.
Wrong. Public funds are not paying for Starship development but for the HLS variant development, at significantly lower cost than the HLS lander from Blue Origin. Which likely still doesn't cover the entire funding even for Blue Origin. A lot is paid by those space companies themselves. A NASA developed lander (Altair from the Constellation program), would probably have cost around an order of magnitude more.
I wouldn't worry too much. It costs more than that to add a bus lane in America.
Survival of our species, for one. Never the mind short-sighted folks like yourselves clawing us back the entire way.
At this point in time the humanity has nothing to offer to any other intelligence (if there is any) out there, nor it doesn't have a need itself to go outside of its own planet, and the big mess that it made out of it. It's akin of letting a toddler walk out of the door and roam into a busy street merely for a satisfaction of its curiousity. What is more likely to happen is that the valuable resources that we still have will be gone (it won't take long, as consumption is growing at exponential rate), without ability to recover - a one way ticket to stone age. It's nice to dream and look at the stars, but can we please sort the shit here first?
Just to Mars, and maybe the asteroid belt. See [0].

To export the enjoyers of capitalism (a.k.a. humans) outside this planet, to visit the stars.
Musk is going to end up killing a lot of people unintentionally.
beautiful although one wonders what they're trying to escape
4M viewers. comparable to top politics events.
ship looks to be lost. this was the main part, so it's almost complete failure.
these tests are designed to fail — the data collected now will ensure they don't blow up with actual people on them. test seems like a success to me
Still a failure in my book, it blew up before it could deliver its payload so they couldn't do many the tests they intended to do.
It is possible they will have to add one more test launch to their schedule, delaying commercial operations because of that.
It is not a complete failure, but to me, it is more failure than success, even by SpaceX test flight standards.
Compared to the previous flight, that I consider a success, the booster catch was nice, but it is not the first, and they have plenty of tries left to perfect it, so it is not in the critical path.
they didn't get the telemetry after, what it was, 16 min(?) hope they'll find the reason which will be hard without black boxes like on airplanes. as every engineer knows it works flawlessly only at the end. if ever.
the booster was the same, great, but not surprising.
IIRC they had 30 cameras on board & who knows how many sensors (probably hudreds ?).
So even if an engine bay fire burned the electronics and interrupted all coms (or FTS blew it up) they should already have a lot of data by that point showing how it went wrong.
You're assuming the viewer count is accurate? That seems rather naive.
Every one of these are like right out of a sci-fi novel. It makes me truly excited for our future in a way little else out there does.
Between this, AI (even in its current LLM form), and mounting evidence suggesting the entire solar system is teeming with at least microbial life, we are going to become an interplanetary species far sooner than many “skeptics” imagine.
We are just one more lander / sample mission / whatever away from having solid proof of life elsewhere in the solar system. That is gonna jumpstart all a huge race to get humans out into deep space to check it all out.
People worry about AI stealing their jobs… don’t worry. We need that stuff so humans can focus on the next phase of our history… becoming interplanetary. Your kids will be traveling to space and these (very overhyped, don’t get me wrong) LLM’s will be needed for all kinds of tasks.
It sounds crazy but I maintain it’s true and will happen sooner than you’d think.
> Your kids will be traveling to space
I can 100% guarantee to you that the children of anyone born today will not travel to space in any significant number. There is nothing in space to travel to until we build extremely complex habitats, and that can't be done with manual human labor, it requires mostly automatic drones and maybe a handful of human controllers living in the ship that brought them there.
And building habitats that any significant amount of people (say, 1000) could actually live in will take a loooong amount of time and a huge amount of resources. And the question of "why would anyone waste time and resources on trying to live in conditions more inhospitable than anything the Earth can ever become, even with a major asteroid crashing into it in the middle of a nuclear war and a global pandemic?" will crop up long before more than one or two of these are finished.
> I can 100% guarantee to you that the children of anyone born today will not travel to space in any significant number
Someone born today will have children living into the early 2100s. The first flight ever was a little more than a hundred years ago. Using your kind of logic, no one would have predicted most of the technology we take for granted today.
> It makes me truly excited for our future in a way little else out there does.
Hate to break it to you, but Space X isn't it. You can't have a CEO that is not aligned to the truth and reality to lead a company into something that is beneficial for humanity.
I like how chopsticks catch (a very impressive feat) completely distracts everyone from totally fucked timeline and already spent budget on mars mission. Its like any criticism is being drowned in loud cheers. Only time will tell, but I hope I will be wrong on this one
What's the criticism exactly? Like I don't get your point? Yes they are behind on timelines and on Mars, does that mean that we should post reddit-tier cynical comments every time about that? I'm not saying that you're doing that, it's more that I don't get why this is surprising.
And on the other hand, it's also funny to see how "skeptics" (whatever that means in this case) dismiss or belittle achievements that were claimed to be impossible a few months or years ago (for example, the chopstick landing). It's like a never ending treadmill of
this is impossible->okay it happened, that's cool, but now xyz is impossible.
Plus, it seems normal to me that people care less about some sort of budget details or delays than really cool technical feats.
They're the ones who were sent in to return two humans from the ISS after Boeing's ship malfunctioned last year. The explosions are typically from R&D projects; SpaceX is capable and practiced at transporting humans (and cargo) without their ships blowing up, and that's where most of their actual business currently is. (The Dragon is the vehicle they use for manned ISS missions.)
I actually get this take, but for me it's the ultimate distraction and a way to legitimize the CEOs rubbish behavior.
"How can he be wrong when he is a genius and can land a rocket in two chopsticks?"
I’m in a slightly different boat. The CEO’s rubbish behavior sucks, but the company shouldn’t be diminished by that. The people behind SpaceX are a modernd day Apollo Program. Absolute marvels of engineering.
The Apollo program was amazing because it was tax payer funded, it was every Americans project. Space X isn't.
They are making the impossible merely late. Which, you know, is still pretty fucking cool.
I’d love to see any other country or competitor catch a stainless steel rocket larger than the Statue of Liberty that was just cruising back to earth at sub orbital velocity. Everybody else is so far behind it’s not even funny.
Spacex is cool as shit. Screw the “skeptics” and haters. Some people have a complete lack of imagination.
Starship started development in 2012. SLS started development in 2011, New Glenn in 2012.
SLS flew in 2022 around the moon. New Glenn just flew, reaching orbit with an actual payload.
Starship hasn't reached orbit, the best they did was send a banana to the Indian ocean.
Remind me again how SpaceX is the fast company?
> very late
when was your fully reusable full-flow staged combustion rocket engine scheduled flight, again?
Why does that matter? SpaceX is setting themselves up for failure by insisting that they need to nail re-entry first. Whenever they focused on a test flight for re-entry I'm wondering why they aren't working on more important things like the payload doors or orbital brimming. They will get the re-entry tests for free!
And even if they don't. The upper stage is cheap enough that it can be expended and still be cheaper per flight than Falcon Heavy. So that tells me that the delays are on purpose. Their test flight planning is designed to maximize ego stroking.
Anyone care to give the non spacey folks like me the highlights of this launch?
