The postponement of Axiom Mission 4 supplies extra time for NASA and Roscosmos to guage the scenario and decide whether or not any extra troubleshooting is critical.”
The area station crew of Expedition 73 is made up of seven astronauts and cosmonauts, who had been anticipating their inhabitants to develop by 4 with the arrival of Ax-4 this week for a couple of two-week go to.
