Defending space : space science and technology shields 2026
A 90% attenuation of high-energy proton flux can be achieved with a nanocarbon-laden polymer shield roughly the size of a marble, according to NASA XLab’s 2026 update. The technology relies on graphene-reinforced epoxy printed in ultra-thin layers, integrated with sensor-driven self-repair mechanisms. Space : Space Science And Technology: 3D-Printed Solid-State
