Another possible launch date for the Uznański-Wiśniewski mission has appeared

NASA, Axiom Space and SpaceX are considering the possibility of launching the Ax-4 mission with Sławosz Uznański-Wiśniewski from Thursday, June 19 - informed in a press release Axiom company organizing a mission to the International Space Station (ISS).

As stated in the company's press release, the launch took place from NASA's Kennedy Space Center. Space Center in Florida will occur “no earlier than Thursday, June 19.”

It was added that SpaceX has fixed a liquid oxygen leak in the rocket Falcon 9, and after the last repairs in the Russian Zvezda module, which is part of the ISS, the pressure remains stable, whereas previously it was decreasing. Both these problems were the reasons for previous decisions to cancel earlier planned starts.

In its statement, NASA said that stabilizing the pressure in Russian part of the ISS may mean that small leaks have been sealed. It was noted, however, that "the teams also take into account that stable pressure may be the result of a small amount of air flowing into the tunnel transfer by sealing the hatch from the main part of the space station."

"Teams assess the condition of the transfer tunnel and seals hatch between the space station and the rear of the Starship," it added.

Falcon 9 rocket passes wet test after oxygen leak repair general", i.e. going through all the starting procedures including refueling.

According to NASA, the current window of opportunity for the mission to launch extends to June 30.

Flight launch - the fourth private mission to the ISS by Axiom Space - It had been postponed three times before; the original date was May 29, next - June 8, 10 and 11. Astronauts - former NASA astronaut Peggy Whitson (commander), pilot Shubhanshu Shukla from India and scientific experts Sławosz Uznański-Wiśniewski and Tibor Kapu from Hungary - will spend up to 14 days on the ISS, performing about 60 scientific experiments, including 13 prepared by Polish scientists. They will fly to the station on board the Crew Dragon capsule - the last one created by SpaceX - for which this will be the first flight into space.

Uznański-Wiśniewski will be the first Polish astronaut on International Space Station.
