LAUNCH OF AXIOM-4 PRIVATE ASTRONAUT MISSION TO ISS, June 25, 2025, KSC, 2:31 am ET (webcast begins 12:30 am ET)

Update, June 24: The launch is still scheduled for early tomorrow morning, June 25, 2:31 am ET.  Axiom and SpaceX will begin their webcast at 12:30 am ET.  NASA+ will join at 1:40 am ET.

Update, June 23;  NASA has set another new launch date — Wednesday, June 25, at 2:31 am ET.

Update, June 19:  NASA has delayed the launch yet again.  It asserts that it needs more time to evaluate the repairs to the PrK module.  The agency is not explaining why it needs additional time to confirm there are no leaks before launching Ax-4 when it launched many crews to the ISS during the years when they knew there were leaks.

Update, June 18:  Axiom now says the launch time on June 22 is 3:42 am ET and the webcast will begin at 1:35 am ET.

Update, June 17:  NASA, Axiom and SpaceX say they now are looking at Sunday, June 22, for launch.  The time wasn’t specified.

Update, June 14: NASA says they are “reviewing launch opportunities no earlier than Thursday, June 19” for this launch. A launch time was not provided.

Update, June 12:  Today NASA said the launch is indefinitely postponed as they and Roscosmos evaluate recent repairs to a compartment in the Russian module that has been leaking air for several years. A number of repairs have been made during that time and more were just made and NASA said they want to assess them before launching Axiom-4.

Snip from NASA’s June 12, 2025 press release:

Update, June 10:  The launch has been postponed again while SpaceX fixes a liquid oxygen (LOx) leak on the Falcon 9 rocket. No new date has been set.
