Researchers at Ghent University in Belgium are developing 3D-printed hydrogels to provide radiation protection for astronauts and spacecraft, addressing the dangers of cosmic radiation that astronauts face beyond Earth's atmosphere. These hydrogels, made from superabsorbent polymers, can absorb large amounts of water, which is effective for radiation shielding without the drawbacks of bulky water containers. The hydrogels retain water in a non-flowing state, ensuring consistent protection and preventing leaks, even if punctured. This innovative approach allows for the customization of radiation shields for spacecraft and spacesuits through 3D printing, enhancing safety for astronauts on long-duration missions to Mars and beyond.
