A new "fabric" designed at NASA'S Jet Propulsion Laboratory in Pasadena, California could one day alter the way astronauts and spacecraft are protected, as well as provide the basis for shape-changing surfaces. The chain mail-looking fabrics are currently in a prototype stage - 3D printed from materials like stainless steel and carbon fiber. The process creates an entire fabric made of just one piece, eliminating the potential points of failure that come with welding materials together. (SOUNDBITE) (English) RAUL POLIT CASILLAS, NASA'S JET PROPULSION LABORATORY SYSTEMS ENGINEER, SAYING: "There's no connection. There's no welding. There is nothing like that. It's all one part and it's one single assembly. That not only makes integration much easier, but also allows you to play with geometries and shapes that you won't be able to do with any other process." NASA hopes that the fabric could eventually provide protection for astronaut suits or act as spacecraft skins. They also hope that the fabric could eventually be a smart fabric - capable of molding itself into various shapes. In addition, fabrics could potentially be printed in space, meaning astronauts could create it as needed. (SOUNDBITE) (English) RAUL POLIT CASILLAS, NASA'S JET PROPULSION LABORATORY SYSTEMS ENGINEER, SAYING: "The idea is you build this in a continuous basis so you don't have to work in the loom and connect the parts, you keep printing, printing, printing." Implementation of the fabrics is still a long way off - perhaps ten years or more. But they represent, what could be, the future of safety, technology, and construction in space.
