HOUSTON (NASA PR) — 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. 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.

Weather permitting, the Ax-1 crew is targeted to close the hatch about 6:45 p.m. Sunday, April 24, to begin the journey home in SpaceX Dragon Endeavour with splashdown off the coast of Florida approximately 1:00 p.m. Monday, April 25.

NASA Ax-1 return coverage is as follows (all times Eastern):

Sunday, April 24

  • 6:30 p.m. – Coverage begins for hatch closure at approximately 6:45 p.m.
  • 8:30 p.m. – Coverage begins for undocking at about 8:55 p.m.

Axiom Space will resume coverage of Dragon’s re-entry and splashdown beginning at noon Monday, April 25, on the company’s website.

The Russian Progress 79 fired its thrusters for 10 minutes, 23 seconds today at 9:25 a.m. This space station reboost maneuver optimizes phasing for future visiting vehicles arriving at the station. The reboost increased the orbiting laboratory’s altitude by 9/10 of a mile at apogee and 1.3 miles at perigee and left the station in an orbit of 264.7 x 254.2 statute miles.
