FAQ

  1. When next launch? (Flight 11) NET October.
  2. When previous launch? (Flight 10) Starship flight 10 launched on 2025-08-26 at 23:30 UTC.
  3. What was the result? All mission objectives fulfilled! First version 2 ship to make it through reentry to landing burn and splashdown. First successful deployment of Starlink simulators. Booster successfully tested landing without one centre engine, using an engine on the middle ring to compensate.

Flight 11 speculation ...

Any chance they put some real Starlink satellites on board (and go all the way to orbit in order to deploy them)?

Any chance they try to land Stage 2 on land, on its skirt? So that they can properly inspect the heat shield (etc.)

  • Perhaps the Aussie outback, if a suborbital flight? If so, they'd presumably need to target a bare patch with no foliage that might catch fire. (The first thought that crossed my mind was, "what about that massive rock?", but I think that might be a little disrespectful ...)
  • Perhaps US territory (desert / salt flats / military range / LZ-4), if an orbital flight?

Any chance they go orbital regardless? I can't think of much reason why they would. I'm assuming they're already very confident that Starship is capable of getting to orbit, but perhaps actually doing it would let them test a full deorbit burn?

I suppose going orbital is a possibility for Flight 11, but I'm not sure that operational Starlink deployments or longer in-space raptor burns are a priority right now.

I highly doubt they attempt a land landing on the skirt. As the goal is ultimately to catch the ship with the chopsticks, I'm not sure if they would learn enough from it to make it worth the hassle. The heatshield in its current form is probably "good enough" to attempt a chopsticks catch in a few more flights, at which point they can inspect the ship at their leisure back at Starbase.

Landing on Uluru would be pretty funny, and reminiscent of the ship from Close Encounters, which landed on that other rock. Not sure if the top of Uluru is flat enough though.
