Boeing’s beleaguered Starliner made its long-awaited return to Earth on Saturday without the astronauts who rode it up to the International Space Station, after NASA deemed it too risky to bring them back aboard the spacecraft.

After years of delays, Starliner launched in June for what was meant to be a roughly weeklong test mission — a final shakedown before it could be certified to rotate crew to and from the orbital laboratory. But unexpected thruster malfunctions and helium leaks on its way up derailed those plans, and NASA ultimately decided it was safer to bring Butch Wilmore and Suni Williams back on a rival SpaceX Crew Dragon — though they’ll have to wait until February 2025. The gumdrop-shaped capsule touched down softly at the White Sands Space Harbor in New Mexico at 0401 GMT, its descent slowed by parachutes and cushioned by airbags, having departed the ISS around six hours earlier.

Ground teams reported hearing sonic booms as it streaked red hot across the night sky, having endured temperatures of 3,000 degrees Fahrenheit (1,650 degrees Celsius) during atmospheric reentry. NASA welcomed the well-executed landing. “NASA and Boeing learned an incredible amount about Starliner in the most extreme environment possible,” said Ken Bowersox, associate administrator of the agency’s space operations mission directorate.

“NASA looks forward to our continued work with the Boeing team to proceed toward certification of Starliner for crew rotation missions to the space station,” he added.

After carrying out extensive ground testing to simulate and overcome the technical issues encountered during Starliner’s ascent, Boeing promised — both publicly and behind closed doors — that it could safely bring the astronauts home. NASA, however, disagreed.

The stakes remain high for the century-old aerospace giant, with its reputation already battered by safety concerns surrounding its commercial jets and its long-term prospects for crewed space missions hanging in the balance. Shortly after undocking, Starliner executed a powerful “breakout burn” to swiftly clear it from the station and prevent any risk of collision — a maneuver that would have been unnecessary if crew were aboard to take manual control if needed. Following that, mission teams conducted thorough checks of its thrusters in preparation for the critical “deorbit burn,” required to guide the capsule onto its reentry path around 40 minutes before touchdown. While expectations were high that Starliner would stick the landing, as it had in two previous uncrewed tests, NASA will now carefully review all aspects of the mission’s performance before deciding on the next steps.
