Successful Raptor on-orbit relight demo! That should clear the next flight to go to orbit and deploy operational satellites! Big milestone for the program.
And the ship landing was so soft it didn't even explode! That's never happened before. And it's still connected to Starlink too. The ship's cameras are still working underwater! I wonder if they will be able to recover it intact?
We're getting some great views of the heat shield post-reentry. That's great data for the heat shield team. The heat shield is the biggest remaining question mark in the whole program. Reflight without heat shield refurbishment will be required for the whole architecture to work, and it's never been done before. None of the heat shields so far looked reusable without refurbishment, including this one.
It might be possible. Allegedly they had previously asked the Australian government about towing the ship back to a port.
Marine recovery can be much more difficult than it might seem though. Towing this nearly 200ft structure weighing a decent fraction of the weight of the boat that is not designed to be seaworthy, potentially full of explosive gasses and that could rapidly start breaking up and taking on water, nearly 300 nautical miles back to shore, would be quite difficult and dangerous. I would be impressed if they ever do it.
They were real satellites but deployed on the suborbital trajectory of this flight, so will have burned up over the Indian ocean about the time that the ship re-entered.
The goal was to get about 20 minutes of testing the new satellites in space, not for them to have any chance of becoming operational.
Starship hasn't been entering a full orbit so far because it would be really bad if the relight burn did fail - chunks of ship would rain down a few days/weeks later on some random area anywhere within 27° of the equator. On a much smaller scale this has been an internationally embarrassing problem for China's LM-5.
Summary: almost, but not quite entirely successful.
Launch successful. Booster separation and boost back burn looked good. Booster failed to relight some of its engines and hit the water hard. Successfully deployed the 20 starlink satellites. Successfully reignited an engine in flight to prove potential for de-orbit burn on future flight. Re-entry looked good and less spicy that some previous attempts (subjective). Such a soft landing that the ship flopped into the water without exploding and floated for a good long while (possibly still floating for all I know). Got some great drone footage flying over the heat-shield.
So the ship itself is looking increasingly good (so far) but they still seem to be having some issues with the booster.
Speaking of which, are there any fan theories on why the boosters seem to have persistent issues? Or is the plumbing still churning fast enough that we keep seeing N=1 issues for successive designs?
It’s interesting the cognitive dissonance this brings out in me. As much as I think Musk carries a fairly reprehensible aura, I would still like to see SpaceX succeed. Space has a funny, transcendent way of inspiring us.
Billions of AI capex for a model that’s consistently forgettable and space computers, presumably data centers in space, are funding SpaceX?
Isn’t the opposite?
SpaceX has an extremely profitable launch program and a profitable Starlink. It’s a straightforward would be better off financially without X and X.ai.
You don't need to virtue signal your dislike of Musk-the-person to be allowed to show your admiration for the exploits of SpaceX. I don't care what you think about Musk and I'm pretty sure I'm far from the only one. Yes, SpaceX is doing great, hopefully other companies will follow their clear lead and make space access more reliable and 'affordable' so that those great wheels-in-the-sky may one day become reality.
Actual, literal Nazis got us to the Moon and frankly no one cared. Not then, not now. Try separating politics from the advancement of humanity, you'll feel better.
"Do you know that your closest colleagues (including von Braun) have stated in company at Zinnowitz that it had never been their intention to make a weapon of war out of he rocket? That they had worked, under pressure from yourself (Dornberger) at the whole business of development and only in order to obtain money for their experiments and the confirmation of their theories? That their object all along has been space travel?"
The men had been arrested by the Gestapo and were going to be executed. Dornberger was also threatened with arrest, but he managed to get von Braun and the other released.
I fucking _loathe_ Trump. I still hope he makes America better. But god I fucking hate him. I think his policies are garbage, but I'd love to be proven wrong. All I see is bribery and nepotism... but yknow, he (finally) nominated Jared Isaacman. I'll fucking take it.
Musk is anathema. But yknow, I'm glad he's started the companies he has.
I don't think your comment adds value to the discussion. By now, you either know what's reprehensible about Musk or have decided to either ignore it or support it, and by extension be reprehensible yourself.
But in case any bystanders genuinely wonder, my personal "favorite" is him doing what is clearly meant to be, or at least unambiguously invoke, a nazi salute not just once but twice, and standing by it (plus, of course, his political activities in that direction).
If he meant it to be a nazi salute, why did he do it in conjunction with saying "I give my heart to you"?
Currently on TV is a WW2 documentary narrated by Tom Hanks. It's pretty good, with significant coverage of nazis. I recommend watching it. I'm a bit of a history wonk, and have read extensively about WW2. I'm afraid I don't see any parallels between the nazis and Musk.
He's done "I give my heart to you" on video, too, and it looks nothing like the nazi salute that he clearly did at the inauguration, twice, in celebration of the victory of far-right populist politics in the USA.
The rhetorical parallels between Musk, his affiliates, and the nazis should be clear to anyone with remedial knowledge of history, let alone someone who calls themselves a wonk: scapegoating racial outgroups isn't a subtle strategy and Musk's pursuit of the strategy is not subtle.
Double Sieg Heil at a US inauguration, buying twitter to boost nazis, sabotaging his US competitors by pulling up the subsidy ladder he just finished climbing, gleefully dumpstering the peanut butter rations for the starving African kids. "Favorite" isn't the word.
Snark aside, I’m curious: what about the comment you replied to is a “Reddit lie?” Pretty much everything act mentioned is well documented. Do you disagree with the assumptions made about motivations for the acts?
Using his billionaire megaphone and telling his millions of followers that a rescue worker was a pedophile, just because basic geometry foiled Musk's plan to look like a Tony Stark action hero <3
Truly top shelf reprehensibility
Would be fucking pathetic and disgusting even for a person with no platform. Downright despicable for a person with such a gigantic following.
Front line rescue workers and first responders are famously required to be polite to looky lou's wanting to make tragic events all about themselves and their dumb PR stunts.
What's authentic/"not phony" about literally making shit up about another person?
I'm genuinely confused so please explain step by step.
Do you think everyone around you is just brimming with unevidenced allegations of pedophilia to fling around at strangers, and finally we have the One True Authentic™ to just bravely say the big words out loud?
Haha nothing funnier than grown adults (??) who are so infatuated with big wockets that they seem to forget basic concepts like "moral character" if there are big wockets anywhere in the vicinity. So smart.
Starship is the SpaceX Cybertruck - lots of impressive engineering, but still doomed by terrible design choices from you-know-who. Stainless steel is just such a terrible choice for a rocket this large. Doomed the whole enterprise.
I know launches are exciting. Landings, doubly so. But eight launches to get to the moon is not a good rocket. Sorry.
Aluminum alloy and carbon fiber, because both have high strength to weight ratios. Steel is denser, so its specific strength isn't as high. But it retains strength at both lower & higher temperatures, and it's much cheaper. It's also cheaper/quicker to modify a steel design, as welding is easier than aluminum (at least for low carbon steels used in Starship). And if the same structure were made of carbon fiber, it would likely have to be fabricated from scratch.
I think choosing steel has helped Starship, as it allowed the ship to survive reentry and land in the ocean despite heat shield failures. Had the ship been made of aluminum, I'm certain earlier missions would have broken up when the aluminum heated up and lost its strength.
They juiced the engines up big time with the Raptor 3 upgrade. The rest of the stack is leaner and meaner too, but engines are probably the single biggest upgrade.
It's why they have plans to elongate the stack further. If they have this much TWR to go around at liftoff, they can afford to cash in that extra thrust to pack more fuel.
Yup. Some of the Youtubers (like NASA Spaceflight) had video of it hitting the water pretty fast and hard. That said, this is the only test failure so far. I'm cautiously hopeful they get Ship to touch down. (it will explode after it does because of physics but stepping lightly onto the ocean will be a win)
And I sit corrected as it was able to lay down without rupturing the tanks and 'sploding. So that's another win.
What I find really amazing and cool is that while its reentering the engineering team can drive it around and look at heating effects on tiles/spars/etc all while retrieving telemetry by Starlink. What many people don't realize is that early capsules were the shape they were because that was the limit of what they could simulate for re-entry forces. The ability to get real time confirmation of systems response in re-entry is a capability that we've never had. So there's that.
So at this point it looks like they are down to un-reliabile raptor relights on the booster.
The size of ship being big enough to create a hole in the ionization to continue to communicate with Starlink is something that I think gets underappreciated.
from what i understand it kind of is a failure. It's suppose to tip over, explode, and sink. That way you don't have all this ITAR regulated tech floating around in international waters.
I am pretty unconvinced that any of the past explosions of starship used that feature. It’s very convenient to have an “explode” button so you can say all of your rocket detonations were intentional, but they are often leaking fuel or dropping chunks before they explode.
Is this just a fancy way of saying lightweight fragile aerospace tube with hot stuff all over the outside and flammable stuff on the inside will not respond well to falling on it's side or is there some other thing going on here I don't know about.
Sort of? Everything is weight. And since it isn't a design feature to lay down in water there isn't any weight budget for making that modality survivable? So typically when it falls (and this thing is really tall) the interior tanks detach from their mounts and hit the inside walls and rupture. The skin is still hot, oxygen and remaining fuel mix and it goes boom. This time we had fires but no boom. I look forward to hearing what was different.
No, that's exactly what happens. Most of the time.
There was a couple of times when SpaceX accidentally soft landed a Falcon 9 first stage into the ocean, and had it just float around. They're yet to do that trick with Starship though.
The actual objective was to crash very slowly into the water, and to that end, I believe they planned for about 13 out of 33 to light for the "landing burn". But only about 5 lit up at that time, giving them a higher-speed crash-landing. However, the landing site was exactly where they needed to be, and done in complete safety, so that is good.
They had been explaining the post-ignition abort from last week, and showed how 4 out of 33 engines had failed to light on the first stage. This was due to some kind of pump malfunctions. They said that if 1 or 2 fail, it's OK to launch, but more than 2 is an automatic abort. So they were able to replace the finicky motors and fully test them out.
Who knows what caused the underthrust for the landing burn, but at least all 33 engines were operational at launch, and they got plenty of data from this test run, and all Starlink v3 satellites have been deployed successfully for their "suborbital speedrun", so this test flight is doing really awesome!
Damn so this probably means another identical suborbital flight in 6-8 weeks. It is looking less and less likely that we will see either prop transfer or a ship catch this year.
i don't think so - the ascent looked good. i don't think they need to put the ship on another suborbital trajectory because the booster landing burn failed. also, i don't think this impacts prop transfer or ship catch - both are separate problems.
I think this is technically true but that they want a seamless suborbital flight (like the last two for the Block 2) before they move forward on those other goals.
Why wouldn’t they only care about seamless ship flights, to get some value out of the launches, while they’re still learning and figuring out how to light booster?
Yes, because it would have landed a few hundred meters out from the chopsticks. It swings in towards the catcher as part of its slowdown. If it doesn't slow down, that doesn't happen.
Its amazing to see this beast and think that all the firey stuff isn't the primary energy source (although totally necessary to pushing the mass out the back fast enough).
The reason it’s very small is that almost all of the energy in hydrogen and oxygen is not stored in the chemical binding energy of these things going together.
The vast majority of it is stored in just the rest mass energy of the protons and the neutrons, which chemical burning doesn’t affect at all.
And the ship landing was so soft it didn't even explode! That's never happened before. And it's still connected to Starlink too. The ship's cameras are still working underwater! I wonder if they will be able to recover it intact?

Mid-stream they said they were deploying 20 real V3 Starlink satellites.
At the end of the stream the said all 20 had checked out as well.

We had it demonstrated in the past with Starship surviving multiple burnthroughts and now in failing to explode. :-)
