NASA's Ingenuity helicopter is currently scheduled to attempt its first flight on Mars toward the end of the day on Sunday.

If the aircraft is successful, the attempt will be the first demonstration of powered, controlled flight on another planet. The experimental vehicle rode to Mars attached to the belly of the space agency's Perseverance rover.
