SpaceX made some progress on another test flight of the world’s most powerful rocket Tuesday, finally overcoming technical problems that plagued the program’s two previous launches.
But minutes into the mission, the SpaceX’s Starship lost control as it cruised through space, then tumbled back into the atmosphere somewhere over the Indian Ocean nearly an hour after taking off from Starbase, Texas, the company’s privately-owned spaceport near the US-Mexico border.
SpaceX’s next-generation rocket is designed to eventually ferry cargo and private and government crews between the Earth, the Moon, and Mars. The rocket is complex and gargantuan, wider and longer than a Boeing 747 jumbo jet, and after nearly two years of steady progress since its first test flight in 2023, this has been a year of setbacks for Starship.
During the rocket’s two previous test flights—each using an upgraded “Block 2” Starship design—problems in the ship’s propulsion system led to leaks during launch, eventually triggering an early shutdown of the rocket’s main engines. On both flights, the vehicle spun out of control and broke apart, spreading debris over an area near the Bahamas and the Turks and Caicos Islands.
The good news is that didn’t happen Tuesday. The ship’s main engines fired for their full duration, putting the vehicle on its expected trajectory toward a splashdown in the Indian Ocean. For a short time, it appeared the ship was on track for a successful flight.
“Starship made it to the scheduled ship engine cutoff, so big improvement over last flight! Also, no significant loss of heat shield tiles during ascent,” wrote Elon Musk, SpaceX’s founder and CEO, on X.
The bad news is Tuesday’s test flight revealed more problems, preventing SpaceX from achieving the most important goals Musk outlined going into the launch.
“Leaks caused loss of main tank pressure during the coast and reentry phase,” Musk posted on X. “Lot of good data to review.”
