[wlug] Linux On Mars: NASA’s Ingenuity Helicopter Flies

The first powered aircraft on Mars <https://www.theregister.com/2021/04/19/perseverance_computing_feature/> has proved its concept, taken flight for a few seconds, and made a controlled landing again. The control system is running Linux on a Qualcomm Snapdragon 801 chip, not because NASA considered it the best tool for the job, but because it was the easiest solution available. The hardware “is tuned for use on Earth, not Mars”, so it is only planned to make brief flights of no more than 90 seconds at a time, always landing back at the same spot, and it is not expected to endure beyond the initial 30 days of the Perseverance mission.
