Overview

• NASA stood down the June 22 launch of Axiom-4 to allow additional checks of the ISS’s Zvezda service module following recent repair work.
• Commanded by Peggy Whitson, the four-member crew includes ISRO astronaut Shubhanshu Shukla along with ESA representatives from Poland and Hungary.
• The astronauts have been in quarantine at Kennedy Space Center and will remain mission-ready until the station is cleared to receive them.
• The current launch window runs through June 30, with a fallback opportunity opening in mid-July if the deadline is missed.
• During their planned 14-day stay aboard the ISS, the crew will conduct nearly 60 scientific experiments across biology, medical research, and microgravity studies.
