Portions of this thread copied from a Starship Dev thread on r/SpaceX.

FAQ

  1. When next launch? (IFT-5) Booster catch NET late July, per Elon.
  2. When previous launch? (IFT-4)? Booster 11 and Ship 29 launched on 2024-06-06.
  3. What was the result? Both booster and ship make it to landing burn and splashdown. Ship flaps took a beating on reentry, but remained in control of the vehicle.

Starbase activities (2024-05-24):

Other:

six engines that shut down early in the boostback burn were disabled from attempting the landing burn startup, leaving seven engines commanded to start up with two successfully reaching mainstage ignition. The booster had lower than expected landing burn thrust when contact was lost at approximately 462 meters in altitude

likely root cause for the early boostback burn shutdown was determined to be continued filter blockage where liquid oxygen is supplied to the engines, leading to a loss of inlet pressure in engine oxygen turbopumps. SpaceX implemented hardware changes ahead of Flight 3 to mitigate this issue, which resulted in the booster progressing to its first ever landing burn attempt. Super Heavy boosters for Flight 4 and beyond will get additional hardware inside oxygen tanks to further improve propellant filtration capabilities

Several minutes after Starship began its coast phase, the vehicle began losing the ability to control its attitude

likely root cause of the unplanned roll was determined to be clogging of the valves responsible for roll control. SpaceX has since added additional roll control thrusters on upcoming Starships to improve attitude control redundancy and upgraded hardware for improved resilience to blockage

  • Also notable: IFT-4 flight test timeline lists "landing burn". I wonder if this will be a soft-water or a hard-water landing?
  • Comparison of IFT-3 and IFT-4 flight timelines.
  • Zack's thoughts on the recent info: Tweet 1, tweet 2, tweet 3, tweet 4.
