Starship’s Second Flight Test
Starship returned to integrated flight testing with its second launch from Starbase in Texas. While it didn’t happen in a lab or on a test stand, it was absolutely a test. What we did with this second flight will provide invaluable data to continue rapidly developing Starship.
On November 18, 2023, Starship successfully lifted off at 7:02 a.m. CT from Starbase in Texas and achieved a number of major milestones:
All 33 Raptor engines on the Super Heavy Booster started up successfully and, for the first time, completed a full-duration burn during ascent.
Starship executed a successful hot-stage separation, powering down all but three of Super Heavy’s Raptor engines and successfully igniting the six second stage Raptor engines before separating the vehicles. This was the first time this technique has been done successfully with a vehicle of this size.
Following separation, the Super Heavy booster successfully completed its flip maneuver and initiated the boostback burn before it experienced a rapid unscheduled disassembly. The vehicle breakup occurred more than three and a half minutes into the flight at an altitude of ~90 km over the Gulf of Mexico.
Starship’s six second stage Raptor engines all started successfully and powered the vehicle to an altitude of ~150 km and a velocity of ~24,000 km/h, becoming the first Starship to reach outer space and nearly completing its full-duration burn.
The flight test’s conclusion came when telemetry was lost near the end of second stage burn prior to engine cutoff after more than eight minutes of flight. The team verified a safe command destruct was appropriately triggered based on available vehicle performance data.
The water-cooled flame deflector and other pad upgrades performed as expected, requiring minimal post-launch work to be ready for upcoming vehicle tests and the next integrated flight test.
With a test like this, success comes from what we learn, and this flight test will help us improve Starship’s reliability as SpaceX seeks to make life multiplanetary. Data review is ongoing as we look for improvements to make for the next flight. The team at Starbase is already working final preparations on the vehicles slated for use in Starship’s third flight test, with Ship and Booster static fires coming up next.
Thank you to our customers, Cameron County, spaceflight fans, and the wider community for the continued support and encouragement. And congratulations to the entire SpaceX team on an exciting second flight test of Starship!
Nothing too surprising. They verified that the FTS on S25 was triggered, but have not said the same for B9. Perhaps the B9 RUD was spontaneous due to the engine/plumbing failures?
