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.

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.

Starbase activities (2024-02-27):

• Feb 27th and 28th road closures cancelled. Temporary road delay scheduled for Feb 28th from 05:00 to 08:00.
• SPMTs deliver counterweights to the launch site overnight, and head towards S28.
• Workers secure S28 forward flaps.
• Ship transport stand positioned to receive S28, and counterweights are loaded onto GMK 7550 crane.
• Chopstick ship pin tested. Extension and retraction.
• Booster transport stand hesitantly approaches Megabay 1 and enters.
• Starfactory progress continues. Starbase Surfer closeup and alternate angle.
• RGV Aerial glamour shot of Rocket Garden.
• Texas Parks and Wildlife out at the launch area, likely cleaning up debris.
• Booster engine compartment dividers spotted on their way to Starbase. The dividers are corrugated core sandwich panels.
• The two horizontal cryo tanks coming from Florida are now on their way. Additional cryo tanks coming from overseas. Arriving ~Mar 5th and 4th.

Starbase activities (2024-02-28):

• B10 is loaded onto transport stand, rolls out to launch pad (RGV Aerial closeup), chopsticks close in (NSF hug shot), and B10 is lifted onto the OLM (NSF angle). Raptors are wearing protection.
• Black LR 11000 crane swings towards S28, picks up the ship lifting jig, sub-orbital pad cleared of non-essential personnel, S28 is hooked up, and lifted onto ship transport stand.
• Can't quite tell what this is a closeup of, but it looks cool. Booster QD?
• The three grey torpedo tanks are shuttled from D2 to D4 (tank 1, tank 2, tank 3), and lifted into place by the Yellow GMK 7550 crane.
• Cryo deliveries continue.
• B14 stacking continues, and another section is spotted.
• Temporary road delay scheduled for Feb 29th from 11:00 to 13:00 or 19:00 to 21:00.
