What You Need To Know This is the Axiom Space company’s fourth private mission to the International Space Station The Ax-4 crew will return with more than 60 experiments About the crew and mission For the retired NASA astronaut, this was Whitson’s second mission for Axiom Space. She was on the company’s Ax-2 mission two years ago. A pilot for the Indian Air Force, mission pilot Shukla became the second Indian Space Research Organization astronaut to go into space since 1984. Uznański-Wiśniewski, a mission specialist, became the second Polish astronaut to go into space since 1978. He is both a scientist and engineer. And because of the Ax-4 mission, mission specialist Kapu became the second Hungarian astronaut since 1980 to go into space. For all three men, it was their first time in space while Whitson has a collected total of time in space at nearly 700 days. And the quartet were busy during those more than two weeks aboard the floating laboratory as they brought more than 60 experiments with them. Some of these experiments are in partnerships with private companies and space programs that include 31 countries. These experiments looked at a few things, such as: “How to support astronauts with insulin-dependent diabetes during short-duration missions in microgravity” “Testing methods to extend pharmaceutical shelf-life in space” “Studying upper atmospheric thunderstorms” On launch day, Axiom Space’s Dr. Lucie Low explained to Spectrum News some of those experiments. Dr. Lucie Low of @Axiom_Space shared with me some of the more than 60 experiments being launched during the #Ax4 mission and which one she is most interested in.
