NASA's Wild Fabric Is Basically Chain Mail From the Future

• https://www.wired.com, Elizabeth Stinson

But space is also an incredibly complex environment, requiring tons of hefty equipment just to exit the atmosphere. To minimize the weight of its payload, NASA has experimented with inflatable materials that can balloon into habitats, and tangles of lightweight rods that can shift shape on different terrains. Now, designers at NASA's Jet Propulsion Laboratory have developed a foldable fabric that could pull triple duty during outer space missions.

Researchers at JPL spent the last two years developing a metallic space fabric made of interlocking stainless steel squares. It looks like chain mail, but unlike the ancient armor, NASA's fabric isn't welded together. Instead a 3-D printer extrudes stainless steel as a continuous sheet of material with different properties on each side. From the front of the fabric, rows of shiny, flat squares can reflect heat and light. On the back, a series of interlocking loops help the fabric absorb heat. Together, the single piece of material acts like a super-strong shield, protecting astronauts and spacecrafts from outer orbit's deadly obstacles.
