This image depicts the demonstration vehicle used to prove that controlled, and sustained flight is feasible in a Martian atmosphere. The first free flight of this prototype Mars Helicopter in atmospheric conditions similar to Mars occurred on May 31, 2016, inside the Space Simulator, a 25-foot-wide (7.62-meter-wide) vacuum chamber at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

NASA's Jet Propulsion Laboratory will build and manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency's headquarters in Washington.
