The W.M. Keck Center for 3-D Innovation at the University of Texas at El Paso will send this first-ever 3-D printed electronics into space. The printed electronics will travel to space inside a CubeSat, a miniature university-based satellite owned by the University of New Mexico that will be launched as part of a resupply mission for NASA—although the electronics are just along for the ride. Preparations for launch begin at 4:30 p.m. El Paso time. Mission is set for liftoff between 5:30 p.m. and 7:15 p.m. from NASA’s Flight Facility in Wallops, VA.
