Axiom Space
Axiom Mission 4 (Ax-4), launching no earlier than May 2025, will be Axiom Space’s most research-focused mission yet, featuring around 60 studies from 31 countries. Key research includes human health in microgravity, cancer cell behavior, and international studies on mental health and biological processes. Led by Commander Peggy Whitson, the diverse crew reflects the mission’s global collaboration. Ax-4 sets the stage for future commercial space research and Axiom’s planned space station.
