Elon said there are an immense number of changes for the next flight. Maybe 6 weeks away.
Also dropped a bombshell that they're moving to hot staging. That's likely what that mystery ring section was. https://twitter.com/elonmusk/status/1672607239608172544 Elon got pissed ended the interview and deleted his tweet. The space is still here https://twitter.com/i/spaces/1OyJAVEdkMaxb |

Elon says there's a much higher chance of getting to orbit with the second test flight due to vast amount of mods. Late breaking change to staging - now hot staging(!). "Never stop thrusting" - Elon Musk 😅 Ship engines will fire up before all the Booster engines shutdown. Now need vents for hot staging. Adding an extension to the booster that is all vent and more shielding to the top of the booster. It's the most risking thing for the next flight. Launch pad upgrades and Booster/Ship ready in six weeks. 1000 cubic meters of steel reinforcement below the OLM. Then a steel sandwich water suppression system on top, with overkill to help the base of the pad. |

Not sure I'm a fan of this new hot staging idea. It seems like another unnecessary complexity. Let the N1 go. They need to focus on getting to orbit and HLS.
Good luck keeping the tiles on it when they fire up those engines. |

Once the next stage is throttled up(in this case Starship) then release the clamps holding Starship and Super Heavy together. Technically challenging, but if done correctly, you dont have to deal with fuel slosh or the decel on the structure from the Super Heavy engine cut and accel on Starship engine start. Kinda nuts on something that big. |

I don’t think they are going to go full fire in the hole staging. They just want to limit the deceleration of the booster before staging to get a cleaner sep. There will not be positive thrust on the booster in that the t/w ratio will be negative.
There will be space between them before the 2nd ignites. |

View Quote You're going to have to break down how that happens if booster is still producing thrust from at least two engines, even throttled down, and the majority of the aero drag is acting on ship. How do they create the separation between stages before starship fires it's raptors? |

View Quote Now, I am not a engineer, or even the holder of a STEM degree, but I doubt that Starship would be capable of a pad abort using only raptors. Even with hot staging, I don't think lighting three to six raptors and burning 100%+ over a methalox bomb until clear would be a great idea. From the Super Draco tests it appears that the capsule gets the fuck outta town in a hurry. I can't see 3 raptors, 6 if county the vacs, performing like that from zero-zero. |

View Quote ETA: Before you say water landing, lets assume the smart guys at SpaceX figure out how to get zero/zero at the surface of the water with empty tanks. Now your meat sacks are at the top of a 15 story building that is going to want to assume a horizontal stability profile. So it's going to tip over and the hapless guys at the top of the rocket are going to take a 15 story fall in a direction that probably doesn't align with the optimum force vector for their seats to protect them. Escape a pad explosion (maybe) and then go for a high-g wild ride, and finally get ripped apart by the seatbelts when your rocket falls over in the wrong direction. |

It does not make sense that it no longer has them. The booster (Super Heavy) is caught with the launch tower chopsticks and the grid fins. |
