News: NASA is testing AstroRad for radiation protection during future Moon and Mars missionsà Developed by StemRad in collaboration with Lockheed Martin.

Why Needed?

• Beyond Earth’s magnetic field, astronauts face higher exposure to solar particle radiation.
• Prolonged exposure increases risks such as cancer and other health problems.

Key Features

• Lightweight vest using hydrogen-rich polymers to slow energetic radiation particles.
• Protects radiation-sensitive organs in the chest, abdomen and pelvis.
• Reduces the weight penalty associated with conventional heavy shielding.

Testing

• Tested by astronauts on the International Space Station (ISS) in 2019–20 for comfort and functionality.

Limitation

• Particularly useful against solar particle events.
• Cannot completely shield astronauts from galactic cosmic rays (GCRs).

Significance

• Provides a lightweight, targeted radiation-protection solution for future deep-space exploration.
