Astronauts stranded in area because of a number of issues with Boeing Starliner — and the window for a return flight is closing
NASA astronauts who traveled to orbit on Boeing’s Starliner spacecraft are presently stranded in area aboard the Worldwide House Station (ISS) after engineers found a number of issues with Boeing’s spacecraft. Groups on the bottom at the moment are racing to evaluate the Starliner’s situation.
Astronauts Butch Wilmore and Sonny Williams have been initially scheduled to return to Earth on June 13 after per week on the Worldwide House Station, however their keep has been prolonged for a second time because of ongoing issues. The astronauts will now return residence no later than June 26, in accordance with NASA.
After years of delays, Boeing’s Starliner capsule efficiently lifted off on its inaugural crewed flight from Cape Canaveral House Power Station in Florida at 10:52 a.m. EDT on June 5. However through the 25-hour flight, engineers found 5 separate helium leaks within the spacecraft. Motivation system.
Now, to offer engineers time to troubleshoot, NASA has introduced that it’s going to postpone the dangerous return journey, extending the crew’s keep on the area station to at the very least three weeks.
“We discovered that our helium system was not performing as designed,” Mark Nappi, Boeing’s Starliner program supervisor, stated in a press convention on June 18. “And regardless that it may very well be managed, it nonetheless wasn’t performing as we designed it. So we You need to go discover out.”
The Starliner spacecraft’s re-entry module is presently docked with the Concord module on the Worldwide House Station as NASA and Boeing engineers consider points with crucial {hardware} on board, together with 5 helium leaks into the system that stresses the spacecraft’s propulsion system, and 5 thrust failures in its response -Management system.

After turning on the thrusters on June 15, engineers discovered that almost all of those issues seem to have been at the very least partially resolved, however their precise causes stay unknown.
Nonetheless, the Concord module’s restricted gasoline means the Starliner can solely stay at anchor for 45 days, so the window for a protected return flight is narrowing.
These points are the most recent in an extended listing of setbacks and complications dealing with Boeing’s spacecraft. The corporate constructed the Starliner capsule as a part of NASA’s Industrial Crew Program, a partnership between the company and personal corporations to fly astronauts into low Earth orbit after NASA’s area shuttles have been retired in 2011. SpaceX’s Crew Dragon additionally got here from this initiative and has Obtain 12 manned flights Since I began working in 2020.
However the Starliner’s first unmanned take a look at flight in 2019 was aborted because of a software program error that put it within the fallacious orbit, and a second try was hampered by issues with a gasoline valve. After additional critiques final yr, the corporate needed to repair issues with the capsule’s parachutes and take away a couple of mile (1.6 kilometers) of tape that was discovered to be flammable.
The present mission is Boeing’s third try to move the crew to the Worldwide House Station. The previous two have been cleaned up by a vibrating oxygen valve on the United Launch Alliance’s Atlas V rocket on which the Starliner was put in (which was developed by Lockheed Martin) and a pc glitch within the floor launch sequencer, respectively.
