WASHINGTON :
 
NASA’s Ingenuity Mars helicopter has survived the first cold Martian night ahead of its maiden flight on the Red Planet scheduled for April 11, the US space agency has said. 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 1.8 kg rotorcraft. This is because evening temperatures at Jezero Crater can plunge as low as minus minus 90 degrees Celsius, which can freeze and crack unprotected electrical components and damage the onboard batteries required for flight, NASA said on Monday.
 
Until the helicopter put its four legs onto the Martian surface, Ingenuity remained attached to the belly of the rover, receiving power from Perseverance, which touched down at Jezero Crater on February 18. In the days to come, Ingenuity will be the first aircraft to attempt powered, controlled flight on another planet.
 
“This is the first time that Ingenuity has been on its own on the surface of Mars,” said MiMi Aung, Ingenuity Project Manager at NASA’s Jet Propulsion Laboratory in Southern California. “But we now have confirmation that we have the right insulation, the right heaters, and enough energy in its battery to survive the cold night, which is a big win for the team. We’re excited to continue to prepare Ingenuity for its first flight test.”
