Liftoff
Counts are flown launches (successes, partial failures and failures) in the SpaceNexus launch record for the calendar year, up to and including this one. The outcome is Launch Library 2’s own label. Booster serials and reuse counts are not in our records; the provider publishes them.
No webcast was linked to Starship V2 · Flight 10 in the launch feed. The provider's own channel is the place to look for a replay.
Liftoff Aug 26, 2025, 23:30 UTC. Live chat ran from two hours before liftoff to two hours after.
Every entry is a change we recorded, not a forecast. Our sync checks Launch Library 2 every 15 minutes, so a time is when we saw the change and can trail the real moment. The liftoff time is the one the launch record states.

Starship (SpaceX)
Starship is two stages: the Super Heavy booster and the Starship upper stage, usually just called the ship. Both run on Raptor engines burning liquid methane and liquid oxygen, and both are designed to be reused. Test flights launch from Starbase in Texas.

The order of events in a Starship test flight, from SpaceX’s published flight plans. A guide, not live tracking: nothing here is ticked off by the clock.
The Super Heavy booster ignites its Raptor engines and climbs away from the tower with the Starship upper stage on top.
The moment of maximum aerodynamic pressure on the vehicle during ascent.
Starship separates with hot staging: the ship lights its own engines while still attached, then pulls away from the booster.
The booster relights some of its engines to reverse course toward its landing point.
Depending on the flight plan, the booster either returns to the launch tower to be caught or makes a landing burn over the water and splashes down. The launch page links SpaceX’s plan for this flight.
The ship shuts down its engines once it reaches the trajectory the flight plan calls for.
What happens in space changes from flight to flight: deploying satellites, relighting a Raptor engine in space, or other tests. Only what the published flight plan names is expected.
The ship enters the atmosphere belly first, protected by its heat shield tiles, and steers its descent with flaps.
The ship flips and lights its engines for a landing burn before touching down in the ocean, or at a landing site when the plan calls for it.
