6. Group Captain Shukla will participate in a space-to-Earth outreach programme and interact with a VIP from space. Seven crew members are already at the ISS.
7. There have been multiple delays for Axiom-4 since the first launch date, May 29, was announced. The delays were linked to varied issues including weather and technical glitches including a leak of oxidizer. June 25 is the sixth date announced by the US space agency NASA.
