A tiny quadcopter could gather rocks for China's sample return mission

Space exploration is always changing. Before February 2021 there had never been a human made craft flying around in the atmosphere of another world (other than rocket propelled landers arriving or departing). The Mars Perseverance rover changed that, carrying with it what can only be described as a drone named Ingenuity. It revolutionized planetary exploration and now, China are getting in on the act with a proposed quadcopter for a Mars sample return mission.
