Washington: Two NASA astronauts – Sunita Williams and Butch Wilmore – who are lodged at the International Space Station, will return to earth next year on a SpaceX vehicle, the space agency informed on Saturday. The two astronauts were earlier scheduled to spend just a couple of weeks in space, however, their stay has exceeded to over 80 nows after the Boeing’s Starliner space vehicle developed technical snags and delayed the return.
Sunita Williams, Butch Wilmore stuck in space since June
The seasoned pilots have been stuck at the International Space Station since the beginning of June. A cascade of vexing thruster failures and helium leaks in the new capsule marred their trip to the space station, and they ended up in a holding pattern as engineers conducted tests and debated what to do about the trip back.
Astronauts to return now on SpaceX aircraft
After almost three months, the decision finally came down from NASA’s highest ranks on Saturday. Butch Wilmore and Suni Williams will come back in a SpaceX spacecraft in February. Their empty Starliner capsule will undock in a week or two and attempt to return on autopilot.
As Starliner’s test pilots, the pair should have overseen this critical last leg of the journey, with touchdown in the US desert.
It was a blow to Boeing, adding to the safety concerns plaguing the company on its airplane side. Boeing had counted on Starliner’s first crew trip to revive the troubled program after years of delays and ballooning costs. The company had insisted Starliner was safe based on all the recent thruster tests both in space and on the ground.
Retired Navy captains with previous long-duration spaceflight experience, Wilmore, 61, and Williams, 58, anticipated surprises when they accepted the shakedown cruise of a new spacecraft, although not quite to this extent.
Before their June 5 launch from Cape Canaveral, Florida, they said their families bought into the uncertainty and stress of their professional careers decades ago. During their lone orbital news conference last month, they said they had trust in the thruster testing being conducted. They had no complaints, they added, and enjoyed pitching in with space station work.
Wilmore’s wife, Deanna, was equally stoic in an interview earlier this month with WVLT-TV in Knoxville, Tennessee, their home state. She was already bracing for a delay until next February: “You just sort of have to roll with it.” There were few options.
The SpaceX capsule currently parked at the space station is reserved for the four residents who have been there since March. They will return in late September, their stay extended a month by the Starliner dilemma. NASA said it would be unsafe to squeeze two more into the capsule, except in an emergency.
The docked Russian Soyuz capsule is even tighter, capable of flying only three — two of them Russians wrapping up a yearlong stint.
So Wilmore and Williams will wait for SpaceX’s next taxi flight. It’s due to launch in late September with two astronauts instead of the usual four for a routine six-month stay. NASA yanked two to make room for Wilmore and Williams on the return flight in late February.
NASA said no serious consideration was given to asking SpaceX for a quick stand-alone rescue.
Last year, the Russian Space Agency had to rush up a replacement Soyuz capsule for three men whose original craft was damaged by space junk. The switch pushed their mission beyond a year, a US space endurance record still held by Frank Rubio.
