NASA has published an account of Dragonfly’s simulated first flight at Titan, rehearsed on a computer testbed at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. The October 23, 2026 report describes a real-time test on flight-like avionics, rather than a physical flight.

The test combined flight software with simulated inputs from navigation cameras, inertial measurement units and lidar, NASA reported. Lidar measures terrain altitude and slope to help identify hazards. The simulated rotorcraft searched for a safe landing site, circled back and descended.

NASA’s mission overview targets launch no earlier than July 2028 and arrival at Saturn’s moon Titan in late 2034. Dragonfly is intended to visit different geological sites and analyse surface samples to investigate habitability and prebiotic chemistry.

The October 23 account does not give the simulation’s exact date. NASA identifies trials on Dragonfly’s actual flight system, additional flight profiles and deliberately introduced faults as further work. Those tests are intended to check how the rotorcraft responds autonomously when something goes wrong.
