NASA and Boeing are proceeding with final preparations to undock the Starliner spacecraft from the International Space Station next Friday, September 6, to head for landing at White Sands Space Harbor in southern New Mexico.
Astronauts Butch Wilmore and Suni Williams, who were supposed to return to Earth inside Starliner, will remain behind on the space station after NASA decided last week to conclude the Boeing test flight without its crew on board. NASA officials decided it was too risky to put the astronauts on Starliner after the spacecraft suffered thruster failures during its flight to the space station in early June.
Instead, Wilmore and Williams will come home on a SpaceX Dragon capsule no earlier than February, extending their planned stay on the space station from eight days to eight months. Flying on autopilot, the Starliner spacecraft is scheduled to depart the station at approximately 6:04 pm EDT (22:04 UTC) on September 6. The capsule will fire its engines to drop out of orbit and target a parachute-assisted landing in New Mexico at 12:03 am EDT (04:03 UTC) on September 7, NASA said in a statement Thursday.
NASA officials completed the second part of a two-day Flight Readiness Review on Thursday to clear the Starliner spacecraft for undocking and landing. However, there are strict weather rules for landing a Starliner spacecraft, so NASA and Boeing managers will decide next week whether to proceed with the return next Friday night or wait for better conditions at the White Sands landing zone.
Over the last few days, flight controllers updated parameters in Starliner’s software to handle a fully autonomous return to Earth without inputs from astronauts flying in the cockpit, NASA said. Boeing has flown two unpiloted Starliner test flights using the same type of autonomous reentry and landing operations. This mission, called the Crew Flight Test (CFT), was the first time astronauts launched into orbit inside a Starliner spacecraft, and was expected to pave the way for future operational missions to rotate four-person crews to and from the space station.
