SpaceX crew launch moved to next week as astronaut recovers

04 November 2021

SpaceX’s next crew flight is off until at least next week, as Nasa debates whether to bring astronauts back from the International Space Station before launching their replacements.

Flight surgeons, meanwhile, are continuing to monitor the “minor medical issue” affecting one of four astronauts awaiting lift-off at Kennedy Space Centre.

Nasa said the astronaut — whom they are not identifying — should be fine before a possible launch attempt on Monday.

But the agency may opt to first bring home the four astronauts living at the space station since April. The soonest they would return in their SpaceX capsule is Sunday; that would further postpone the next crew launch.

“The weather in November can be especially challenging, so our goal is to move forward on the plan with the highest probability of mission assurance and crew safety,” Nasa’s commercial crew program manager, Steve Stich, said in a statement.

The US-German crew should have rocketed to the space station last weekend, but poor weather along the flight path pushed the flight to Wednesday. But then one of the astronauts was sidelined for undisclosed medical reasons, and the launch was bumped to this weekend.

But with more bad weather anticipated, SpaceX and Nasa called it quits until next week.

Nasa said managers will make a final decision soon on whether to prioritise the launch or splashdown, based on weather. They are also reviewing how many days would be needed between the two events.

Also factoring into the equation is the amount of time a SpaceX capsule can remain in orbit before its systems are degraded. The company’s Dragon capsules are designed to spend 210 days aloft; the one up there now logged day 195 on Thursday.

Additional analysis could extend the acceptable amount of time, according to Nasa.

If the four astronauts come home first, the station will remain occupied by an American and two Russians.
