In this photo from June 28, 2025, Expedition 73 flight engineer Jonny Kim and former NASA astronaut and director of human spaceflight at Axiom Space Peggy Whitson work together inside the International Space Station's Destiny laboratory module setting up hardware for cancer research.
The hardware is used to culture patient-derived cancer cells, model their growth in microgravity, and test a state-of-the-art fluorescence microscope. Results of this study may lead to earlier cancer detection methods, development of advanced cancer treatments, and promote future stem cell research in space.
Whitson returned to Earth on July 15, 2025, with fellow Axiom Mission 4 crew members ISRO (Indian Space Research Organisation) astronaut Shubhanshu Shukla, ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland, and Hungarian to Orbit (HUNOR) astronaut Tibor Kapu of Hungary. They completed about two and a half weeks in space.
