SpaceX crew launch deferred to next week

SpaceX's next crew flight got postponed till last week, as NASA is yet to take a call on whether to bring the astronauts back from the International Space Station before sending their replacements. The US-German crew was initially scheduled to be launched to the space station last weekend, but the launch got delayed due to bad weather.

Cape Canaveral (US): SpaceX's next crew flight is off until next week, as NASA debates whether to bring astronauts back from the International Space Station before launching their replacements. Flight surgeons are continuing to monitor the minor medical issue affecting one of four astronauts awaiting liftoff at NASA's Kennedy Space Center.

NASA said on Thursday that the astronaut whom they're not identifying should be fine before a possible launch attempt on Monday. But NASA 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 programme 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 prioritiss the launch or splashdown, based on weather. They're 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.
