SpaceX Scrubs Wednesday Rocket Mission To ISS After Hydraulic Issues

The two astronauts that have been stranded in space for the last nine months will have to wait a little longer.

SpaceX on Wednesday night, about an hour before launch, postponed their rocket launch mission to the International Space Station. That came after issues with hydraulics on the launch pad.

The four-person crew was scheduled to relieve Butch Wilmore and Sunni Williams, returning them to the United States by Sunday afternoon.

The two have been stranded on the ISS since June, after their Boeing Starliner spacecraft had mechanical issues and was deemed unsafe for them to return.

SpaceX says they have another window for launch on Thursday evening, but did not say if they would be attempting a launch then.
