Ingenuity (helicopter)

Ingenuity, informally called Ginny, is a small autonomous helicopter presently operating on the planet Mars. It is part of NASA's Mars 2020 mission. The helicopter arrived on the Martian surface attached to the underside of the Perseverance rover, which landed on February 18, 2021. The helicopter was deployed to the surface on April 3, 2021. Both the rover and the helicopter began their missions on Mars at the Octavia E. Butler Landing site near the western rim of the wide Jezero crater. On April 19 it made the first powered, controlled extraterrestrial flight by any aircraft. During its first flight Ingenuity took off vertically, hovered, and then landed. It flew for a total of 39.1 seconds during that attempt. As of its most recent flight on August 4, 2023 (UTC), the helicopter has flown a total of 1 hour 35 minutes and 31 seconds in 54 successful attempts over days. The flights have demonstrated the helicopter's ability to fly in the extremely thin atmosphere of Mars, just 0.6% as thick as the air on Earth. It proved that flight was possible on other planets without the direct human control that the finite speed of light makes impractical (depending on the positions of the two planets, radio signals take between 5 and 20 minutes to travel between the Earth and Mars). As a result of this delay Ingenuity must autonomously perform the maneuvers planned, scripted and transmitted to it by its operators. The helicopter was intended to perform a 30-sol technology demonstration, making five flights at altitudes ranging from for up to 90 seconds each. Before Ingenuity's first flight, Perseverance drove approximately away to create a safety buffer between itself and the helicopter. The success of Ingenuity's first flight was confirmed three hours after its completion by JPL, which livestreamed a view of mission control receiving the data. On April 30, 2021, during its fourth flight, Perseverance recorded the sound of Ingenuity during operation, making it the first interplanetary spacecraft whose sound was recorded in situ by another interplanetary spacecraft.
