The Ingenuity helicopter is expected to fly next month.

Ingenuity, the $80 million small helicopter that hitchhiked a ride to Mars on the Perseverance rover, will make its first flight early next month, likely no earlier than 8 April, NASA’s Jet Propulsion Lab (JPL) announced today. If successful, it would be the first controlled powered flight on another planet.
