NASA, SpaceX delay flight that was to retrieve stuck astronautsbr br NASA and SpaceX on Wednesday, March 12, delayed the launch of a replacement crew of four astronauts to the International Space Station that would have set in motion the long-awaited homecoming of US astronauts Butch Wilmore and Suni Williams.br br NASA had been set to launch a SpaceX rocket from Florida carrying a replacement crew for the International Space Station in a mission that would set up the return to Earth of Wilmore and Williams — stuck in space for nine months after a trip on Boeing's faulty Starliner.br br The launch was called off due to a hydraulic system issue with a ground support clamp arm for the Falcon 9 rocket, NASA said in a statement. NASA said it is now targeting a launch no earlier than 7:03 p.m. EDT (2303 GMT) Friday, March 14, after mission managers put off a launch attempt on Thursday, March 13, because of high winds and rain forecast in the flight path of Dragon.
