3D-Printed Hydrogels: A New Shield Against Cosmic Radiation for Astronauts
Scientists are exploring a novel use for 3D-printed materials: creating protective hydrogels to shield astronauts from cosmic radiation. The European Space Agency (ESA) sees great potential in this technology for both crewed and uncrewed missions.
Water is known for its radiation-shielding properties due to its high density and hydrogen atom concentration. Hydrogels, which bind water within their structure, are being developed as an effective radiation shield. They ensure even distribution of water, providing consistent protection.
Research groups at institutions like MIT, NASA, and the University of Pittsburgh are working together to refine this technology. They are exploring the use of superabsorbent polymers (SAPs) as an improved alternative to traditional hydrogels. The next step is to refine manufacturing techniques and scale production for space use.
3D printing allows for the creation of hydrogel structures in almost any shape. This makes them suitable for use in spacesuits and space stations, where space is limited.
3D-printed hydrogels are proving to be a promising solution for radiation shielding in space. With further development, they could significantly enhance the safety and efficiency of future space missions, both manned and unmanned.
