Meet the Astronauts

“With a culturally diverse crew, we are not only advancing scientific knowledge but also fostering international collaboration. Our previous missions set the stage and with Ax-4, we ascend even higher,  bringing more nations to low-Earth orbit and expanding humanity’s reach among the stars.”

Peggy Whitson,  Ax-4 Mission Commander

The Ax-4 crew includes members from India, Poland, and Hungary, marking each nation’s first mission to the space station in history and second government-sponsored human spaceflight mission in over 40 years.  

  • Shubhanshu Shukla became India’s second national astronaut to go to space since 1984.
  • Sławosz Uznański-Wiśniewski, European Space Agency (ESA) project astronaut, is the second Polish astronaut since 1978.
  • Tibor Kapu is the second national Hungarian astronaut since 1980.
  • Peggy Whitson is commanding her second commercial human spaceflight mission, adding to her standing record for the longest cumulative time in space by an American astronaut.
  • Ax-4 is the second commercial spaceflight mission made up of government and ESA-sponsored national astronauts.
  • The Ax-4 mission stands as a beacon of opportunity for India, Poland, and Hungary, each poised to leverage this mission to advance their national space programs.
MISSION Research

The Ax-4 research complement includes around 60 scientific studies and activities representing 31 countries, including the U.S., India, Poland, Hungary, Saudi Arabia, Brazil, Nigeria, UAE, and nations across Europe. This will be the most research and science-related activities conducted on an Axiom Space mission aboard the International Space Station to date, underscoring the mission's global significance and collaborative nature to advance microgravity research in low-Earth orbit (LEO). The mission emphasizes scientific portfolios led by the U.S., India, Poland (in partnership with ESA), and Hungary. It aims to boost participation in these countries by involving diverse stakeholders, showcasing the value of microgravity research, and fostering international collaboration. The studies will enhance global knowledge in human research, Earth observation, and life, biological, and material sciences, demonstrating the space research capabilities of the crew's home nations.
