Ingenuity (helicopter)

Ingenuity, nicknamed Ginny, is an autonomous helicopter that operated on Mars from 2021 to 2024 as part of NASA's Mars 2020 mission. Ingenuity made its first flight on 19 April 2021, demonstrating that flight is possible in the extremely thin atmosphere of Mars, and became the first aircraft to conduct a powered and controlled extraterrestrial flight. It was designed by NASA's Jet Propulsion Laboratory (JPL) in collaboration with AeroVironment, NASA's Ames Research Center and Langley Research Center with components supplied by Lockheed Martin Space, Qualcomm, and SolAero.

Ingenuity was delivered to Mars on 18 February 2021, attached to the underside of the Perseverance rover, which landed at the Octavia E. Butler Landing site near the western rim of the 45 km-wide (28 mi) Jezero crater. Because radio signals take several minutes to travel between Earth and Mars, it could not be manually controlled in real time, and instead autonomously flew flight plans sent to it by JPL.

Originally intended to make only five flights, Ingenuity completed 72 flights over the course of nearly three years. The five originally planned flights were part of a 30-sol technology demonstration intended to prove its airworthiness with flights of up to 90 seconds at altitudes ranging from 3 to 5 meters (10 to 16 ft). Following this demonstration, JPL designed a series of operational flights to explore how aerial scouts could help explore Mars and other worlds. In this operational role, Ingenuity scouted areas of interest for the Perseverance rover, improved navigational techniques, and explored the limits of its flight envelope. Ingenuity's performance and resilience in the harsh Martian environment greatly exceeded expectations, allowing it to perform far more flights than were initially planned. On 18 January 2024, the rotor blades were broken during landing on flight 72, permanently grounding the helicopter.
