Agnirva Space Premier League - Expedition #32261: Building Space Shields: Protecting Astronauts from Gamma Rays

Space travel exposes astronauts to intense cosmic radiation, including dangerous gamma rays that can damage DNA and increase cancer risk. The "Space Shields" experiment, conceived by Michelle Lucas and the Higher Orbits team, investigated how well different materials could passively shield against gamma radiation.

Deployed during Expeditions 51/52, the experiment tested various composite materials onboard the ISS. Unlike active shielding, which uses energy to block radiation, passive shielding relies on placing dense or reflective materials between the radiation source and the astronaut. The goal was to measure which materials were most effective, lightweight, and suitable for use in spacecraft walls or astronaut suits.

This research is critical as we prepare for missions to the Moon, Mars, and beyond. With limited room and weight allowances on spacecraft, finding the most efficient shielding method could save lives and make deep space travel safer and more feasible.

The insights from Space Shields will help engineers design smarter protective gear and spacecraft interiors that prioritize astronaut health without compromising mission efficiency.
