The first time an airplane has landed on another planet is when NASA sends a helicopter to Mars.
NASA's four-pound helicopter successfully soared from the surface of Mars early Monday, making it the first powered flight of an aircraft on another planet, a feat NASA officials equate to the Wright Brothers' first flight in 1903.
The chopper, called Ingenuity, rose off the surface of Mars at around 3:30 a.m., reaching an altitude of about 10 miles, where it hovered, turned, and landed softly in an autonomous flight that lasted just 30 seconds, according to the space agency.
