As for the Falcon 9, SpaceX reported on the afternoon of June 12 that the static fire was completed. SpaceX is now waiting for direction from NASA and Axiom Space.
As of Saturday, June 14, the launch is now no earlier than Thursday, June 19.
"Cosmonauts aboard the space station recently performed inspections of the pressurized module’s interior surfaces, sealed some additional areas of interest, and measured the current leak rate. Following this effort, the segment now is holding pressure. The postponement of Axiom Mission 4 provides additional time for NASA and Roscosmos to evaluate the situation and determine whether any additional troubleshooting is necessary," the statement read.
NASA deferred comment to Roscosmos.
On June 14, NASA released the following update:
"Following the most-recent repair, pressure in the transfer tunnel has been stable. Previously, pressure in this area would have dropped. This could indicate the small leaks have been sealed. Teams are also considering the stable pressure could be the result of a small amount of air flowing into the transfer tunnel across the hatch seal from the main part of space station. By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda."
The earliest parts of the ISS have been in orbit since 1998, and it is currently set for decommission by 2030. SpaceX is contracted to safely deorbit the space station in a remote area of the ocean sometime after 2030.
Issues on the aging ISS are not new. A NASA Office of Inspector General report released late last year raised concerns about whether it would be safe or even affordable to operate past the 2030 date.
