StemRad's AstroRad Vest Successfully Tested on Artemis I for Radiation Protection
Key points
- AstroRad vest flew on Artemis I mission to the Moon and back.
- Flight data showed the vest protects against solar storm radiation.
- Performance was comparable to Orion's onboard radiation shelter.
- Addresses the challenge of limited shielding mass in spacecraft.
Radiation Protection for Deep Space Missions
Astronauts on missions to the Moon or Mars face significant radiation risks from solar storms, which can cause cancer or radiation sickness. Earth's atmosphere and magnetic field provide natural protection, but spacecraft currently lack sufficient shielding for deep space environments.
AstroRad Vest's Lunar Test
StemRad, an Israeli-American startup, developed the AstroRad wearable radiation-shielding vest as an alternative to shielding entire spacecraft. The vest was tested aboard NASA's uncrewed Artemis I mission, flying to the Moon and returning to Earth. Data from this flight was used to assess its performance during a simulated solar storm.
Performance and Impact
The AstroRad vest demonstrated protection against radiation comparable to the Orion spacecraft's heavily shielded onboard shelter, where crew members would typically seek refuge during a solar storm. This targeted shielding approach addresses the long-standing challenge of mass limitations in spacecraft design, where every gram added for shielding is a significant consideration.
Rethinking Shielding Strategies
For decades, spacecraft designers have explored various shielding options, including aluminum hulls and water-filled walls, but all faced the constraint of mass. The concept of a wearable shielding garment was previously considered impractical due to the perceived need for heavy, high-density materials like lead, which would impede astronaut mobility. The AstroRad vest offers a new perspective on efficient radiation protection for future human space exploration.

Reporting from
StemRad's AstroRad radiation-shielding vest was flown to the Moon and back on NASA's uncrewed Artemis I mission, demonstrating its effectiveness in protecting against solar storm radiation. The vest performed comparably to the Orion spacecraft's heavily shielded shelter, offering a solution for astronaut protection in deep space where traditional spacecraft shielding is insufficient.
