The Starliner is scheduled to undock from the International Space Station and to make its way back to Earth at 6:04PM Eastern time on September 6 at the earliest. If the weather cooperates and the spacecraft leaves the ISS as planned, it will be landing at White Sands Space Harbor in New Mexico with the help of parachutes to slow its descent and inflated airbags at around 12:03AM ET on September 7. While the ground teams at Starliner Mission Control in Houston and at Boeing Mission Control Center in Florida can control the spacecraft remotely if needed, it will be an uncrewed, fully autonomous flight for the Starliner.
NASA recently announced that Butch Wilmore and Suni Williams, the astronauts that headed to the ISS aboard the Starliner for its first crewed flight, will be coming home on a SpaceX Crew Dragon instead. Wilmore and Williams flew to the ISS in June and were only supposed to spend a little more than a week on the orbiting laboratory. On the way there, however, five of the spacecraft’s maneuvering thrusters had failed, and its helium leak problem that previously caused its launch to be pushed back had worsened. Engineers on the ground conducted tests with help from the astronauts on the ISS to determine whether the Starliner was safe for the crew to ride back to Earth. In the end, NASA decided that it’s safer for Wilmore and Williams to come home on a SpaceX vehicle, because “there was too much uncertainty” around the Starliner’s thrusters.
The space agency will cover Starliner’s return live on NASA+, the NASA app and its website. As for the SpaceX Crew-9 mission that’s replacing the Boeing’s vehicle on the ISS, it’s scheduled to launch no earlier than September 24. Instead of flying with four astronauts as planned, it will fly with two — NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov — to leave two seats empty for its return flight with Wilmore and Williams in February 2025.
