A research team from Ghent University in Belgium is exploring the use of 3D-printed hydrogels as effective radiation shields for astronauts during spaceflight. Current challenges with water-based radiation protection include bulkiness and leak risks. Hydrogels, which can absorb significant amounts of water and retain it in a non-flowing form, may provide a more efficient and safer alternative. This material can help protect astronauts from harmful cosmic radiation while allowing for greater mobility and safety. The team aims to develop customizable hydrogel structures through 3D printing, potentially enhancing both manned and unmanned space missions.
