Mission patch SpaceX Starship flight tests

Starship flight test 6 was the sixth flight test of a SpaceX Starship launch vehicle. The prototype vehicles flown were the Ship 31 upper stage and first stage Booster 13. The flight test started on November 19, 2024, at 22:00:00 UTC (4:00 pm CST, local time at the launch site).

Although the flight had a similar profile to Flight 5, a suborbital flight to the Indian Ocean, it had several changes to gain flight data for future ship recovery and reuse. The ship reentered the atmosphere at a steeper angle to test the limits of the flaps, and certain parts were outfitted with new thermal protection materials. Certain areas of the heat shield were removed in anticipation of the addition of catch hardware on future ships, which will be needed to land the ship on the arms of the launch tower. Flight 6 was the first flight to include an in-space burn of a single Raptor engine, demonstrating the deorbiting capability of Starship. The launch occurred at a later time of day than previous flights to enable the ship to descend to the ocean in the daylight at the landing location for better visual observations. This was the last flight of the Block 1 Starship upper stage. Block 2 and, eventually, Block 3 will be used for future flights.

Background

Vehicle testing ahead of launch

Starship Ship 31 (S31) was rolled to Masseys Test Site at SpaceX Starbase in Texas for cryogenic testing on May 11. During its first cryogenic test on May 12, an electrical anomaly occurred, and Starship Ship 31 was rolled back to the production site for repairs on May 15. S31 completed a successful cryogenic test in early July. S31 completed a successful static fire on September 18. It was rolled to launch site on November 11.

Super Heavy Booster 13 (B13) was moved to the Orbital Launch Pad on October 22. While on the launch pad it conducted a static fire of all 33 of its Raptor engines on October 24. It was rerolled to the launch site and stacked with S31 on November 14. On November 17 B13 and S31 conducted a partial tanking test ahead of launch.

Mission profile

The mission profile for flight test 6 mirrored the trajectory of flight test 5, with Starship launching on November 19, 2024, at 22:00:00 UTC (4:00 pm CST, local time at the launch site). At T+ 2:39, the Starship upper stage hot-staged from Super Heavy, and continued its ascent. Although Super Heavy was supposed to return to Starbase, the booster catch was called off due to a loss of communication to the launch tower. It was later found that during launch a communications and weather station antenna were bent from the engine plume. Instead, Super Heavy came down for a controlled landing in the Gulf of Mexico where it soon broke up. Its liquid oxygen tank section continued to float before being sunk the following day. Later that night it appeared that SpaceX had the United States Air Force shoot the booster in the water making it sink. It was thought to be done to keep internal components secret and for SpaceX to recover the booster later in the future.

Shortly after, Ship 31 shut its engines down, entering a coast phase. The upper stage Starship spacecraft reached an initial apogee of 190 km (120 mi) and a perigee of 8 km (5.0 mi) at a 26.3 degree orbit, marking the first time Starship has had positive perigee. At 22:37:46, the Ship successfully conducted the first Raptor engine relight in the vacuum of space, which raised the apogee to 228 km (142 mi) and the perigee to 50 km (31 mi). Starship reentered the atmosphere at 22:47:13, and at 23:05:24, Starship performed a controlled splash down in the Indian Ocean, which marked the first time Starship landed from space during daylight hours.

Payload

A stuffed banana served as the zero-g indicator, becoming Starship's first payload, though it remained within the vehicle for the duration of the flight.
