WASHINGTON — NASA and Boeing have pushed back the return of the CST-100 Starliner spacecraft from the International Space Station until at least early July to continue studies of propulsion system problems.
In a statement issued late June 21, NASA announced it was no longer proceeding with plans announced three days earlier to have Starliner depart the station June 25, landing at White Sands, New Mexico early June 26, to complete the Crew Flight Test (CFT) mission with NASA astronauts Butch Wilmore and Suni Williams on board.
Unlike three previous delays, NASA did not disclose a new departure date for Starliner. Instead, NASA stated only that it is “evaluating future return opportunities” for the spacecraft after a scheduled spacewalk July 2, the second of a pair of spacewalks planned at the ISS.
The NASA program managerThe NASA statement did not disclose long Starliner could stay at the station, only that the crew “is not pressed for time to leave the station since there are plenty of supplies in orbit” and there are no other missions scheduled to go to the station through mid-August. Stich said at a briefing just after Starliner’s June 6 docking that the spacecraft could remain at the station for 45 days.
“We thought we had fixed that problem,” Stich said, adding, “I think we’re missing something fundamental that’s going on inside the thruster.”


The US space agency is set to face a flurry of questions about recent reporting from media outlets suggesting the space agency is considering returning Wilmore and Williams on a SpaceX vehicle instead.

That's insane.
“Because what we do is complex, I firmly believe that we need to get closer to the production lines and development programs across the company,” Ortberg said in the letter. “I plan to be based in Seattle so that I can be close to the commercial airplane programs.”
But according to the report, Boeing’s quality control systems fall short of NASA’s requirements, and some known deficiencies have gone unaddressed. What's more, the workers on the project are not, as a whole, sufficiently experienced or well trained, according to the inspector general.
