FAQ

  1. When next launch? IFT-3 is NET Mid-March, 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.

Starbase activities (2024-01-21):

  • 9th, 10th, and 11th stringers installed on the OTF shells. The use of a "dent puller" was required in a couple cases. Unclear at this point whether all shells will receive reinforcements, or just these two.
  • Starfactory expansion is pretty quiet, though a new fence has been erected.

  • 8th stringer installed on the OTF shells.
  • Cross-bracing installation begins on the OTF shells.
  • Zack Golden's thoughts on the concrete issue: "If you pour too quickly, pressure will continue to rise at the bottom as additional material is added. Eventually this head pressure can reach a point where it becomes too great for the form work to handle, resulting in a collapse."

Wow. I don't think I realized how gargantuan the megabay is.

Yeah, I think it's 2-3 times the floor space of the current high bay, and slightly taller. Megabay 2 is similar size to Megabay 1. Definitely huge buildings, though still not as big as the VAB at the Cape.

Starbase activities (2024-02-04):

  • Pretty quiet Sunday.
  • S28 gains a raptor engine.
  • Production site: Cones set up for potential transport to or from Sanchez or RocketGarden, but no road closures scheduled. A few more beams have been added to Starfactory since yesterday.
  • New hardware spotted at Sanchez site. Likely a production jig or transport stand for hotstage rings.

I wonder what happened that caused them to abandon today's WDR attempt.

Interesting thread regarding distribution of segments for the top of the 3rd (2nd at Starbase) launch tower. Seems like the top 3 will all be two-thirds height, as opposed to the full-height, two-thirds, one-third segments on the 1st tower.

Starship update video released. Some highlights:

  • S25 failure: Intentional LOx venting caused an unintentional fire and explosion.
  • IFT-3 flight plan includes a deorbit burn from header tanks.
  • 2nd launch tower at Starbase confirmed.
  • Full stack could eventually stretch to 150 m, with an aspirational goal of 200 tonnes to orbit, fully reusable.

Starbase activities (2024-02-15):

  • Many cryo tankers overnight, one obscured by birb.
  • Feb 15th road closure revoked. No closure listed for Feb 16th, but possible (but unlikely due to holiday) closure listed for Feb 20th.
  • Lift up near B10 hot stage ring for much of the day.

IFT-2 updates from SpaceX:

  • Booster failure:

  • several engines began shutting down before one engine failed energetically, quickly cascading to a rapid unscheduled disassembly

  • Cause:

  • most likely root cause for the booster RUD was determined to be filter blockage where liquid oxygen is supplied to the engines, leading to a loss of inlet pressure in engine oxidizer turbopumps

  • Zack Golden and Ryan Hansen speculate that blockage could have been slosh baffles which broke free during the period of negative acceleration. Ringwatchers relevant article.

  • Fix:

  • implemented hardware changes inside future booster oxidizer tanks to improve propellant filtration capabilities and refined operations to increase reliability

  • Ship failure:

  • A leak in the aft section of the spacecraft that developed when the liquid oxygen vent was initiated resulted in a combustion event and subsequent fires that led to a loss of communication between the spacecraft’s flight computers. This resulted in a commanded shut down of all six engines prior to completion of the ascent burn, followed by the Autonomous Flight Safety System detecting a mission rule violation and activating the flight termination system

  • Fix:

  • implemented hardware changes on upcoming Starship vehicles to improve leak reduction, fire protection, and refined operations associated with the propellant vent to increase reliability. The previously planned move from a hydraulic steering system for the vehicle’s Raptor engines to an entirely electric system also removes potential sources of flammability

  • FAA mishap investigation has been closed. SpaceX must complete corrective actions, of which there are 17.

Viewing individual tweets on nitter seems to be over, though I can still view them chronologically on account profile pages. Not sure what I will do once this breaks too...
