The world’s first all-private crew to the International Space Station must wait at least another day to depart the orbiting lab after bad weather prevented a planned undocking Saturday (April 23). 

NASA, SpaceX and the company Axiom Space, which is backing the private Ax-1 mission, called off plans to undock a SpaceX Dragon carrying its four-man crew due to unacceptably high winds at splashdown sites off the coast of Florida. Mission managers had been aiming for a Saturday evening undocking before the delay.

“At the conclusion of a weather briefing ahead of today’s planned undocking, NASA, Axiom Space, and SpaceX teams elected to wave off today’s undocking attempt due to a diurnal low wind trough which has been causing marginally high winds at the splashdown sites,” NASA officials wrote in an update Saturday. “The Axiom Mission 1 (Ax-1) crew is now targeting to undock from the International Space Station 8:55 p.m. EDT Sunday, April 24.”
