Starship Development Thread #52

SpaceX Starship page

Portions of this thread copied from the Starship Dev thread on r/SpaceX.

FAQ

  1. When next launch? IFT-3 is NET Feb 2024, and after completion of the IFT-2 mishap investigation. Candidate vehicles are Booster 10 and Ship 28.
  2. When previous launch? (IFT-2)? Booster 9 and Ship 25 launched on 2023-11-18.
  3. What was the result? Successful lift off with minimal pad damage. Successful booster operation with all engines to successful hot stage separation. Booster destroyed by AFTS after attempted boost-back. Ship fired all engines to near orbital speed then destroyed by AFTS. No re-entry attempt.
  4. Was IFT-2 a complete failure? No. As part of an iterative test programme, many milestones were achieved. Perfection is neither expected nor desired at this stage.

Thanks for this! Really want to keep up with the goings on in space but it's really hard without Reddit.

threelonmusketeers@sh.itjust.works · 3 pts · 2y (4 replies)

Glad to hear that people find these threads useful! Feedback and suggestions are always welcome.

When do you think we'll see IFT-3? January? February? March?

sleep_deprived@lemmy.world · 5 pts · 2y (2 replies)

I'm really hoping for before '24 of course because of the yearly launch limit, but realistically I think January is possible and February is most likely. I'd be surprised if it isn't before March unless there's extenuating circumstances, e.g. FAA or lawsuits.

threelonmusketeers@sh.itjust.works · 4 pts · 2y

Rumours are that February is the internal target date, so I wouldn't be too surprised if it slipped to March. End of '23 would definitely be a treat though!

extenuating circumstances, e.g. FAA or lawsuits

I'm hoping this shouldn't be as long of an issue as last time, given that there wasn't a delayed FTS, and there was minimal damage to ground infrastructure.

John_Hasler@lemmy.one · 1 pts · 2y

Kathy Lueders said that this month is unlikely but seems to think that there's a chance for January. I'll go with that.

John_Hasler@lemmy.one · 2 pts · 2y

I think that a launch this year is still possible but I wouldn't want to give odds. I think that before the end of January is likely. It would be cool for it to happen on my birthday but I'd rather see it earlier.

In other Starship news, Kathy Lueders (now general manager of Starbase) states that they are working to shift as much testing as possible from the launch site to Masseys.

Starbase itself is a hotbed of construction activity these days, she said, with a second orbital launch pad on tap as well as a million-square-foot factory, additional employee housing and office space all coming online, she said. The second pad is necessary for SpaceX’s goal of a faster launch cadence, while much of the engine testing is now taking place at SpaceX’s Massey test site on a former gun range west of Starbase, Lueders said.

“That test site is very critical,” she said. “What it allows us to do is keep our test operations … away from the beach. We know that it’s a pain in the butt for everybody when we have to (be) close the beach. And so we’re moving more of our testing over there so that it doesn’t impact operations that are over near the beach.”

She also confirms that the AFTS was triggered on IFT-2:

Lueders said Starship’s anomaly investigation team was still looking into why the Nov. 18 flight’s Automated Flight Termination Systems were activated.

Daily summary compiled from users on the Starship dev thread over on Reddit

12/15/23

It appears that Tower Pieces are being moved from Florida to Texas. The launch ring in Hangar M at the Cape might roll out onto a barge soon. There was a second tower under construction at 39A, and parts at Roberts Road were intended for a second Starship tower at KSC. SpaceX initially planned a second tower at Boca Chica but dropped the permit request. Now, it seems the tower segments at Roberts Road are destined for a second Starship tower in Boca Chica, possibly for launching and landing Tanker Starships in a rapid salvoing process. It seems like the limiting factor might be the tank farm's capacity to fill Tankers with methalox. The ultimate goal may be controlling multiple Ships in LEO for refilling missions. Tower segments are being transported to Starbase, with various activities observed throughout the day.

threelonmusketeers@sh.itjust.works · 4 pts · 2y

Thanks for posting this! Looks like this is OLT #3 segment 7.

  • Not too much action today.
  • No observed changes to S26. Still connected to up to a crane in the rocket garden.
  • Work on the OLM continues
  • The SpaceX LR 11000 crane was rolled over to the launch tower. Later in the day, the crane was connected to the Ship Quick Disconnect arm. Looks like they're planning on lowering at least a portion of it. (Rover 2.0 Cam)
  • For the first time in several days, I didn't spot any lifts at S28. Perhaps this means it is ready for rollout tonight?

threelonmusketeers@sh.itjust.works · 3 pts · 2y

Ah yes, I found some video here and here. It seems like they didn't lower the flex pipes or work on them, correct? They just lifted them out of the way so they could access other components?

John_Hasler@lemmy.one · 6 pts · 2y (3 replies)

The LR11000 has moved into the space near gate D2 where they recently demolished the storage sheds. I think it's there to handle the last three horizontal tanks (unless it's just there to compact the new asphalt...)

threelonmusketeers@sh.itjust.works · 4 pts · 2y (2 replies)

Thanks for posting! For posterity, here a link to the video of the crane movement.

Vicki and Zack speculate that it could be there to remove one of the old vertical tanks currently used for water storage.

John_Hasler@lemmy.one · 2 pts · 2y (1 reply)

That looks like a long reach from where it's parked.

John_Hasler@lemmy.one · 1 pts · 2y

But there's a guy up on one of the veritcal tanks working on the lifting rings so perhaps Zack is right.

They're now cutting up the shell of one of the vertical methane tanks. They managed to suck all the perlite out when we weren't looking.

threelonmusketeers@sh.itjust.works · 2 pts · 2y (1 reply)

These vertical "methane" tanks never ultimately held methane, did they? Just water and (maybe?) some LN2 or LOx?

I recall something about Texas regulations stipulating that the tanks were too close together to safely hold fuel...

John_Hasler@lemmy.one · 3 pts · 2y

It's been asserted that they were used for water but I know of no evidence that they actually were.

Texas regulations require that the design for a methane storage system be done by a registered professional engineer certified to do methane storage systems in Texas and be submitted for approval before construction starts. Thus it's unlikely that they were "too close together". More likely they just didn't work right. Perhaps they had an excessive boiloff rate or too high a leakage rate.

Speculation: Perhaps they decided to build their own tanks because lead times for purchased tanks were too long. It worked out for LN2 and LOX.

I wonder why they have not recycled the suborbital tanks?

Really hoping for no major setback after what happened during the last tests with the booster.

threelonmusketeers@sh.itjust.works · 3 pts · 2y (1 reply)

Yeah, same. That detanking procedure on the most recent B10 test did not seem norminal.

B10’s SPMTs did leave the launch site today, so hopefully that indicates that B10 is healthy enough to continue the testing campaign.

ludu@sh.itjust.works · 3 pts · 2y

Now with an overpressure notice for tomorrow, I'm hopeful it's a good sign that even if something major happened, the booster did not take a serious hit.

Starship Development Thread #53

Lichtblitz@discuss.tchncs.de · -6 pts · 2y (6 replies)

As part of an iterative test programme, many milestones were achieved. Perfection is neither expected nor desired at this stage.

Sounds reasonable, except for the final bit. It's just ridiculous to claim that perfection was not desired. Sensors provide the same data, investors will be happier and invest more, clients will gain more trust and spend more. It feels like the excuse some kid would come up with, who is lacking self confidence to stand by their limited success and claimed it was all intentio... oh.

threelonmusketeers@sh.itjust.works · 6 pts · 2y (2 replies)

It’s just ridiculous to claim that perfection was not desired.

I think this refers to SpaceX's hardware-rich iterative development process. The quote "if you never fail, you're not pushing the boundaries enough" sums up the sentiment well.

John_Hasler@lemmy.one · 2 pts · 2y (1 reply)

If you never succeed you are pushing them too hard.

A test that goes to completion always returns more data than one that doesn't. For example there is a theory that the flaps on the ship are too large. IFT2 could have confirmed or falsified it.

threelonmusketeers@sh.itjust.works · 1 pts · 2y

Hmm, interesting take. Do you think SpaceX's current IFT goals are too ambitious? If you were in charge, what modifications would you make to the testing schedule?

xvlc@feddit.de · 2 pts · 2y (2 replies)

I think you are reading too much into this. SpaceX has a rather aggressive test program, and the purpose of the tests is not (only) to verify the functionality of the system, but also to learn about the vehicle and involved technologies. At this stage they are pushing the boundaries of the systems capabilities intentionally up to the point where it might start to fail. So if things don’t fail, it only means that they could have pushed harder and squeezed out more performance.

That does not mean that anyone wants Starship to explode. But the objective is clearly not to do a perfect launch, because SpaceX knows that it’s more efficient to make mistakes a few times times and then succeed, instead of spending excessive amounts of time and money one single perfect test launch. This has been communicated very clearly from the very beginning.

Lichtblitz@discuss.tchncs.de · 0 pts · 2y (1 reply)

Not really. It has been communicated very clearly that if there wasn't a successful starship launch every two weeks by 2022 (I believe that's the year Elon Musk used?), SpaceX runs the risk of bankruptcy. At this point what they are doing means, that he wasn't truthful when he said that, or that they are failing unintentionally and downplaying it, or that they are actually very far behind their plans and heading toward bankruptcy.

John_Hasler@lemmy.one · 1 pts · 2y

"Runs the risk" means it might happen, not that it will happen. When he said that Starlink was committed to switching to the version two satellites and F9 was not expected to be able to launch them. They would have missed their FCC deadlines. However, they were able to develop the "shrunken" Starlink2 that fits on F9. I also think that both the F9 launch cadence and Starlink sales have exceeded expectations.
