摘要

On 19 April 2021,its twin rotors stirring the wispy Martian atmosphere,Ingenuity,the National Aeronautics and Space Administration(NASA)miniature helicopter,lifted off the surface of the Red Planet[1].Built by NASA's Jet Propulsion Laboratory in California,the 0.5 m tall craft did not perform any fancy aerobatics.It climbed to an altitude of 3 m,hovered,turned 96°,and then landed.But the 39 s flight was remarkable because it was the first by an aircraft on a planet other than Earth[1].
