The success of Ingenuity, which became the first aircraft to operate on another planet, opened the way for the next stage of NASA’s aerial exploration efforts on Mars. NASA is now focusing on more advanced aviation technologies, with one of the key research areas being the ability of rotor blades to exceed the speed of sound under Martian atmospheric conditions.
Specialists have successfully completed tests of an upgraded flight system adapted for the harsh conditions of the Red Planet. According to agency representatives, the new design is capable of reaching speeds above Mach 1, which could significantly expand the capabilities of future research missions.
Engineers at Jet Propulsion Laboratory (JPL) are applying the experience gained from operating Ingenuity to further develop a recently introduced project known as Skyfall. Although the first Martian drone has officially completed its mission, Skyfall is intended to continue that work by supporting both robotic and crewed expeditions.
A key feature of the new vehicles will be a substantial increase in rotor speed. While the previous model was limited to 2,700 revolutions per minute, developers of the next-generation system aim to achieve significantly higher performance.
Physical conditions on Mars differ significantly from those on Earth. At sea level on Earth, the speed of sound is approximately 1,223 km/h, while in the thin, carbon dioxide–rich Martian atmosphere it is closer to 869 km/h. To evaluate system reliability, researchers simulated these conditions in a space simulation chamber at Jet Propulsion Laboratory, where they tested rotors developed by AeroVironment.
Initial tests showed that the blades withstood loads at 3,750 revolutions per minute, corresponding to roughly Mach 0.98. After an additional air-boost system was activated, the blade tips reached Mach 1.08. According to the researchers, this technological improvement could allow future helicopters to carry up to 30% more payload.
NASA plans to use the Skyfall system for more than aerial observation. The vehicles are expected to carry a range of scientific instruments and sensors designed to collect detailed data on the Martian atmosphere, surface conditions, and potentially even the planet’s internal structure. The updated design will also support larger battery systems, enabling longer flights. As part of the planned Skyfall mission, three aircraft are expected to be deployed to Mars simultaneously. Based on data collected during recent tests, engineers are already refining the mission’s technical parameters ahead of a projected launch in December 2028.
