We’re still flying half a ship!
Absolutely incredible performance. There are obviously some areas for improvement (booster engine out, flap seals), but the booster soft landing and ship controlled reentry were both huge steps forward.
On to IFT-5! Put some payloads on it!
Confirmed payload for IFT-4! /S
Landing burn startup!
Edit: And shutdown!
Couldn’t really see how the landing burn went, but the telemetry indicated that velocity slowed to just a few km/h at zero altitude.
I can’t believe they (maybe) completed the landing burn with a shredded flap.
Between that and the booster engine issues, this seems like one of the best possible learning scenarios.
That flap was the real MVP of this mission. The little (big) flap that could.
I am curious how much of that flap was still there.
If you watch carefully during landing burn, you can see it actuate a little but then sheer sideways. It was still attached but uhh, slightly less reusable than expected lol. It looked pretty wedged in place as the final shots show the ship fully stop moving. Just incredible! I really hope we see any kind of tracking shots externally in the near future.
Soft landing for super heavy ✅ Starship cruising in space ✅
A couple of engines failed, but wow, so much improvement on each flight.
The Super Heavy hover looked way more stable than I was expecting. Amazing progress.
The gridfins started getting active and I got some bad flashbacks, but they reigned it in for a really impressive soft landing
Yeah, I was getting nervous when the booster was plummeting at mach 2 only 10 km up and that grid fin started oscillating, but the landing burn looked super smooth, even with one engine out.
One of the forward flaps appears to be disintegrating…
Mission Control Audio: “Ship approaching max-Q. Temperatures are dropping.”
Mission Control Audio: “Ship passed through max-Q.”
Mission Control Audio: “Starship is subsonic.”

Ship R-vac engines cutoff, followed shortly by center engines cutoff, and nominal insertion.
Hot staging, and boostback burn!
Liftoff!
Landing burn and soft splashdown of the booster!
Super impressive, especially given that the booster lost an engine early on, which must have eaten into the propellant budget.
Hot stage ring jettison!
Looks like one booster engine is out. Max-Q occurred around the right time, though (T+1:01).
Ship camera feed reacquired at T+36:56. Nice view of one of the flaps with earth in the background.
SpaceX webcast hosts return at T+40:33.
Great to see the full flight paths achieved, that means tons of data they can use for future iterations on the design. Getting to see it all happen live on video is such a treat!
That was incredible. Can’t wait for ground footage of the ship landing burn.
