Scientists from the Korea Institute of Science and Technology have developed a new material that could shield humans and critical technology from harmful radiation in space. The material is thinner than a human hair and stretches like rubber, and could protect instruments and humans in the process. It was developed to block electromagnetic and neutron radiation from spacebound tech from these types of radiation, which can pose risks to damaging or interfering with nearby tech as well as human health. The researchers aim for this lightweight material to be a lighter weight option for protecting equipment and humans involved in spaceflight. While its lightweight nature and stretchiness could potentially double its length, the material's flexibility allows it to be 3D-printed. The development of this new material was described in the journal Advanced Materials.
