Private Astronauts Launch Historic Long ISS Mission

Axiom Space's AX-4 mission launched four private astronauts on a historic long-duration ISS mission. The multinational crew will conduct 60 experiments from 31 countries during their 14-day stay, advancing research in health, technology, and education while paving the way for commercial space stations.

A New Era in Space Exploration

Axiom Mission 4 (AX-4) made history today as the first fully private long-duration mission to the International Space Station. The multinational crew lifted off aboard a SpaceX Falcon 9 rocket from Kennedy Space Center at 2:31 AM EDT, marking a milestone in commercial spaceflight.

Meet the Pioneering Crew

Commanded by former NASA astronaut Peggy Whitson, the AX-4 team includes:

  • Shubhanshu Shukla (India), the nation's second astronaut
  • Sławosz Uznański (Poland), ESA project astronaut
  • Tibor Kapu (Hungary), mechanical engineer

This mission represents the first ISS visit for all three nations and their return to human spaceflight after 40+ years. Whitson, already holding the record for longest cumulative time in space by an American, adds another chapter to her legendary career.

Groundbreaking Research Agenda

During their 14-day mission, the crew will conduct approximately 60 experiments from 31 countries, including:

Health and Biology Studies

The "Cancer in LEO" project will examine tumor growth in microgravity, while "Myogenesis" researches muscle atrophy solutions. Diabetes management in space will be tested through the "Suite Ride" experiment using insulin monitoring systems.

Technology Demonstrations

Innovations include the "Leopard ISS" computing platform for algorithm testing and "RadMon" radiation detectors. The "Axiom Suit" fabric study will analyze thermal regulation during exercise.

Earth and Education Projects

Crew members will conduct live ham radio sessions with students worldwide and perform STEM demonstrations like Hungary's "Space Basics" physics experiments.

The Future of Commercial Space Stations

AX-4 advances Axiom Space's plan to launch the first commercial space station by 2030. "These missions build the foundation for Axiom Station," said Chief of Mission Services Allen Flynt. As NASA prepares to retire the ISS by 2030, private stations will become crucial for continued low-Earth orbit research.

The Dragon spacecraft "Grace" docked with the ISS on June 26, beginning the most extensive private research mission in space history. NASA's Dana Weigel noted: "This professional collaboration allows us to shape the future of low-Earth orbit."
