Making it through the frigid Martian temperatures after being deployed by NASA’s Perseverance rover is a major milestone for the small rotorcraft.  

PASADENA, Calif. (NASA PR) — NASA’s Ingenuity Mars Helicopter has emerged from its first night on the surface of Mars.

Evening temperatures at Jezero Crater can plunge as low as minus 130 degrees Fahrenheit (minus 90 degrees Celsius), which can freeze and crack unprotected electrical components and damage the onboard batteries required for flight. Surviving that first night after being deployed from where it was attached to the belly of NASA’s Perseverance rover on April 3 is a major milestone for the 4-pound (1.8 kilograms) rotorcraft. In the days to come, Ingenuity will be the first aircraft to attempt powered, controlled flight on another planet.
