Semi-autonomous rotorcraft have revolutionized terrestrial geological and atmospheric science. Their ability to explore high and low, far and wide allows them to deploy instrumentation and collect remote-sensing data in regions and from perspectives otherwise difficult or impossible to access. The success of the Ingenuity Mars helicopter similarly opens prospects for transforming the study of Mars. Rotorcraft on Mars can facilitate geological and geophysical investigations, enable atmospheric measurements, and assist human exploration. Future missions to Mars could involve these aircraft as complements to ground-bound assets, such as rovers or fixed stations, or as stand-alone vehicles. In this presentation, I’ll talk about what we learned from the Ingenuity effort and what we might learn from the upcoming SkyFall and other missions.
