The Ingenuity helicopter, which has been fluttering around the red planet for almost three years now, fell out of contact with Perseverance, the rover that brought it to the planet (and that it communicates with using Zigbee!). NASA wrote yesterday that the flight, its 72nd, was a test of its systems after it was forced to land it early during its previous flight. The agency is working toward reestablishing contact. While we wait, here’s a recent video of the helicopter in action.
Nothing that high level. Different systems are running independently, some may be redundant to each other in case one fails. But run something long enough especially in extreme conditions and things can drift from the baselines. If a power off and on regularly prevents that it’s a lot easier than trying to chase down gremlins that could be different each time they pop up for different reasons.
Even NASA I believe has done such resets from Apollo through the unmanned probes from time to time. Mentioning Windows, the newest versions don’t really do this baseline reset if you just shut them down, even if you disable the hibernate/sleep modes, while a restart does.
