Assuming the stack gets to and survives separation on the next flight (or the next or however many it takes ...), then sure. That booster will simply orient ass-forward and fall toward the water. Once at terminal velocity and effectively 1G, restart should be as close to "nominal" as it will ever be. Assuming the right number of engines restart and don't start consuming themselves, great. Huzzah. There will be much rejoicing as it settles into the water.

Are you sure? All of the flight profiles I recall seeing here call for the first flight to have a boostback and and landing a few miles offshore of the launch site.

My opinion is that Ship 25 will seperate and light up 5 of its engines i thing that only 2 of the RC engine will light
Booster 9 will lose 1 engine upon boostback and have 12 engines to complete the boostback burn and then the 3 engine will light for the final landing burn
For the ships reentry iit will inevitably fail on reentry
Thoughts

That's a very detailed projection. Good luck to you!

I predict 100% success.

Elon Musk has decided on a novel method of Starship stage separation for the upcoming second launch of the Starship:

That’s not novel.

lykos · « **Reply #47 on:** 06/26/2023 07:37 am »

For Starship it is.

So was the other method, or ANY method.

lykos · « **Reply #49 on:** 06/26/2023 07:44 am »

Exactly!
Novel for Starship,
novel for SX,
novel for a reusable rocket.
So, where is the problem?

It’s a misuse of the word “novel.”

It is certainly novel to shift to that method of stage separation after the vehicles have already been mostly built...it will be interesting to see how this goes.

The system is in development. It still hasn’t completed its first orbit. The Falcon 9 system was going to parachute back to earth and ended up being redesigned for retro-propulsive landings. We are just seeing an evolution of design choices. They will iterate and change things till it is successful, reliable/safe quick to turn around/reply and low cost to operate. Expect many changes over the next few years. I consider it an amazing honor to to have as much insight on these changes as they happen for an adolescent rocket program.big thanks to the ring watchers and other eyes on the ground. Plug for L2 also… well worth the money!

I haven't seen any speculation on a launch date. Any guesses out there? Any significant dates coming up that they might target? Is there a poll?

My bets would be around December likely.

From what he was saying, the launch should’ve been more than a month ago.

We don’t even have a booster out at the pad yet…

Starmang10 · « **Reply #58 on:** 07/13/2023 10:17 pm »

Also, speaking of which, does anyone think that S25 will get that sleek thermal-paint that S24 received?

At the least, Elon's statement without the reality distortion field directly points NET mid August.

Poll

How many engines will fail during IFT-2 first stage flight (not counting not-ignited)
