Re: SpaceX Starship : Texas Prototype (s) Thread 25 : Discussion. So the plan is to cut the booster thrust back to some non-zero value while the SS engines are cranking up to a currently planned 50%, then separating. Once SS is clear the booster will gimbal for the flip with uninterrupted thrust.
SpaceX F9/Dragon 2 : CRS2 SpX-31 : KSC LC-39A : 30 October 2024 (04:49 UTC) Started by AndrewM.
SpaceX would love to recover the second stage, which they had planned. But it sounds like they have given up on that. Transcript - Elon Musk at MIT's Aero/Astro Centennial (part 1 of 6) [What about the second stage?] The next generation vehicles after the Falcon architecture will be designed for full reusability.
The biggest difference is the nozzle.For optimal performance in vacuum, you want a much larger one. According to Spaceflight 101, the chamber pressure is the same, but the expansion ratio (throat area to end-of-nozzle area) is 7 times larger in the vacuum variant, which (if correct) implies about 2.7 times the nozzle diameter if the throat is unchanged.

It's the same reason SpaceX often does things differently: Krypton is a lot cheaper. The satellites are designed to control costs. For example, each will maneuver with Hall-effect thrusters—ion thrusters in which propellant is accelerated by an electric field.
196. SpaceX uses an Actor-Judge system to provide triple redundancy to its rockets and spacecraft. The Falcon 9 has 3 dual core x86 processors running an instance of linux on each core. The flight software is written in C/C++ and runs in the x86 environment. For each calculation/decision, the "flight string" compares the results from both cores.
The reasons CH 4 is a front runner for SpaceX's Raptor can probably be attributed to four factors: Methane does not coke (polymerize) at the operating temperatures of a rocket engine – it's coking point is roughly twice as high. This makes it easier to make an engine reusable and re-usability is a key SpaceX objective.
I'll be in Miami this Thursday 30th of March and there is a SpaceX Falcon 9 rocket launch from LC-39A, Kennedy Space Center, Florida (if it's not delayed). I won't be able to drive north to be on time at Cape Canaveral to see it.
