Takeoff was slated for Wednesday evening from Kennedy Space Center in Florida, but the company called off the launch attempt because of an issue with the launchpad’s ground system. The problem stemmed from a hydraulics system used to control one of two clamps that hold on to the upper portion of the rocket as it sits vertically on the ground pad before launch.

On board the Crew-10 mission are NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov.

NASA postponed Crew-10 launch to March 14 due to weather concerns and a hydraulic issue with Falcon 9 rocket. Crew-10 marks SpaceX's 10th crew rotation mission under NASA's Commercial.
