There’s currently only one example of an aircraft that has made a powered, controlled extraterrestrial flight—the Mars Helicopter—but based on its performance, it won’t be the last. Designed as a technology demonstrator, Ingenuity’s success has delighted scientists at NASA’s Jet Propulsion Laboratory, logging more than 70 flights and more than 2 hours of flight time. And yes, NASA keeps a logbook for the aircraft.
