Starship flight test 9 will be the ninth flight test of a SpaceX Starship launch vehicle. Ship 35 and Booster 14 or Booster 16 are expected to fly on this test flight.^[2][3]

As of March 2025, Ship 35 has finished its assembly in Mega Bay 2,^[4] with the configuration of its heat shield hinting at catch hardware.^[5] B16 is fully assembled, and underwent cryogenic testing on February 28.^[6][7] On January 18, B14 was rolled back for refurbishment.^[8]

NASASpaceflight has claimed that B14 may fly for a second time on flight 9, having previously flown on flight 7.^[9] If so, B14 will likely perform another static fire before launch.^[1][10]

After Flight 6, Elon Musk stated that flight 8 could be the first 'catch' of the Ship should flight 7's landing be successful.^[11] Due to the failure of S33 to complete its ascent burn, this was delayed to a later mission,^[12] along with the likely required insertion into Low Earth orbit.^[13] Before flight 8, it was believed that flight 9 will feature the first catch attempt,^[14] with FCC permits for flight 9 stating the potential for a catch.^[15] However, flight 8 also failed during the ascent burn, delaying the ship catch to a future mission.^[16]
