Space radiation is one of the most formidable challenges when it comes to human spaceflight. During Axiom Mission 4 (Ax-4), this topic was brought front and center during an on-orbit event with �����о��� Chief Scientist Dr. Lucie Low, Ax-4 Commander Peggy Whitson, and Mission Specialist Sławosz “Suave” Uznański-Wiśniewski, who was previously a CERN engineer. They explored how radiation affects both astronauts and the technology that supports them, and how the mission is helping advance solutions for space exploration.

Radiation in space comes from high-energy particles emitted by the Sun and distant cosmic sources. While Earth’s atmosphere and magnetic field offer protection, astronauts in low-Earth orbit and beyond face much higher exposure. This radiation can damage DNA, increase cancer risk, impair cognitive function, and affect the cardiovascular system, posing serious risks for long-duration missions to the Moon and Mars.

So how do we protect astronauts? ������� has been tackling this question since the first private astronaut mission to the International Space Station. On Axiom Mission 1, the crew tested a designed to protect vital organs while remaining comfortable and unobtrusive. Axiom Mission 2 introduced a to evaluate its effectiveness in blocking harmful particles. Axiom Mission 3 explored that could be used in future spacecraft and suits. Now, on Ax-4, the crew is testing commercial dosimeters. One study, the study, led by Polish researchers, focuses on developing scalable radiation sensors for real-time monitoring, aiming to improve models of the space radiation environment and enhance the reliability of future space systems. Another project, from the Hungarian to Orbit Program, monitors crew radiation exposure and environmental conditions during the Ax-4 mission via miniaturized devices designed for everyday personal wear.

As humanity prepares for deep space exploration, ������� missions are laying the foundation for safer, more resilient missions. From wearable sensors to advanced shielding and real-time monitoring, the innovations being tested today are shaping the future of human spaceflight.
