NASA indefinitely delays return of Starliner to review propulsion data

“We are letting the data drive our decision."

The announcement followed two days of long meetings to review the readiness of the spacecraft, developed by Boeing, to fly NASA astronauts Butch Wilmore and Suni Williams to Earth. Advertisement The NASA update did not provide any information about deliberations during these meetings, but it is clear that the agency's leaders were not able to get comfortable with all contingencies that Wilmore and Williams might encounter during a return flight to Earth, including safely undocking from the space station, maneuvering away, performing a de-orbit burn, separating the crew capsule from the service module, and then flying through the planet's atmosphere before landing under parachutes in a New Mexico desert. "We are strategically using the extra time to clear a path for some critical station activities while completing readiness for Butch and Suni’s return on Starliner and gaining valuable insight into the system upgrades we will want to make for post-certification missions," Stich said.
