Notes

  • AstroRad is a radiation protection vest developed by StemRad and Lockheed Martin for spaceflight.
  • The vest targets protection of the chest, abdomen, and pelvis, which contain vital organs and blood-forming bone marrow.
  • It utilizes hydrogen-rich polymers rather than dense materials like lead; hydrogen nuclei are effective at slowing energetic particles through energy transfer during collisions.
  • Artemis I mission (2022) tested the vest using two human-shaped dummies, Helga and Zohar, with Zohar wearing the vest.
  • Data analysis published in Science Advances indicates AstroRad could reduce effective radiation doses from historical solar storms by 40% to 60%.
  • The vest is designed to mitigate solar radiation risks, allowing astronauts to continue working during solar storms.
  • A limitation of the vest is its inability to block galactic cosmic rays originating from outside the solar system.
  • Radiation exposure beyond Earth's magnetic field poses significant health risks, including cancer.
