How origami machines might unlock secrets of Mars and the universe

March 23, 2017 --If some NASA researchers have their way, Mars exploration technology of the future may rely on an art form from the past. NASA's Jet Propulsion Laboratory (JPL) has developed a Pop-Up Flat Folding Explorer Robot (PUFFER) prototype that could change how we explore Mars. The rugged yet portable machine takes its inspiration from the art of origami, which, despite Americans' association with grade-school arts and crafts, is proving to be a cutting-edge design philosophy. Recent developments in the field have led to an explosion of uses ranging from solar panels to bulletproof barriers. What sets PUFFER apart from other rovers is that it folds flat, making its mini-profile even slimmer.
