NASA and SpaceX rescheduled the launch of their Falcon 9 rocket rescue mission to the International Space Station for Friday.

They were unable to launch on Wednesday due to issues with equipment on the ground, and opted to scrub a Thursday launch attempt due to weather.

“NASA and SpaceX have scrubbed Wednesday’s launch attempt of the agency’s Crew-10 mission to the International Space Station due to a hydraulic system issue with a ground support clamp arm for the Falcon 9 rocket at Launch Complex 39A at NASA’s Kennedy Space Center in Florida,” they wrote in a Wednesday statement. 

They said launch teams were waiting for ideal weather and adjustments to the hydraulic systems ground support clamp before slating the rocket’s next departure. 

“Mission managers met this evening and decided to wave off a launch attempt on Thursday, March 13, due to high winds and precipitation forecasted in the flight path of Dragon,” NASA and SpaceX wrote in a Thursday update.

“NASA’s SpaceX Crew-10 now is targeting no earlier than 7:03 p.m. EDT Friday, March 14, to launch four crew members to the International Space Station,” they said.

Astronauts Anne McClain and Nichole Ayers from NASA, Takuya Onishi from Japan Aerospace Exploration Agency, and Kirill Peskov, Roscosmos cosmonaut are expected to be on board the Crew10 mission.

They will meet NASA’s Butch Wilmore and Suni Williams to take over their Crew9 mission and help the two astronauts, who have been at the International Space Station for nine months, return home.
