Mars in the Air: NASA bets on helicopters as the new surface explorers

NASA is shifting away from new Mars landers or rovers in the near term and betting on aerial drones, led by the SkyFall helicopters that will ride to Mars with the SR-1 Freedom nuclear‑electric propulsion testbed. SkyFall, a three‑helicopter demonstrator (plus a spare) planned for launch as early as late 2028, will separate from SR‑1 and autonomously land, carrying science payloads like a ground‑penetrating radar and transmitting data via orbiters. The mission foregoes a full rover payload, highlighting a push for a repeatable helicopter platform amid budget constraints and a broader move toward commercial partnerships for Mars exploration.
