Ingenuity, NASA’s autonomous Mars helicopter, was only meant to complete five flights. But since its history-making first flight in April 2021, the helicopter has flown 28 times, and preparation is underway for the 29th. Depending on dust levels and the schedule of the rover Perseverance, that flight could take place as soon as later this week. But now Ingenuity faces a new challenge: It’s unclear if the helicopter will survive the coming Martian winter, which begins in July.
Since a Martian year amounts to roughly two years on Earth, and the helicopter is in the northern hemisphere, this is Ingenuity’s first winter. As the solstice approaches, days are getting shorter and nights longer, and dust storms could become more frequent. That all means less sunlight for the solar panels mounted above the helicopter’s twin 4-foot rotor blades. Dust on solar panels recently spelled the end of operations for NASA’s InSight Mars lander, and the effects of cold on electronics is believed to have played a role in the end of the Opportunity and Spirit Mars rover missions.
