At JPL in California, engineers tested larger rotor blades for NASA's planned three-helicopter SkyFall mission, which could launch in late 2028 aboard the nuclear-powered Space Reactor-1 spacecraft.
The advance is aimed at helping bigger Mars rotorcraft carry heavier payloads farther through an atmosphere about 1% as dense as Earth's sea-level air and perform a new self-landing manoeuvre.
It builds on Ingenuity, which flew 72 times after arriving with Perseverance before a January 2024 crash-landing, proving aerial exploration could reach terrain inaccessible to rovers.
After Ingenuity's blades failed, how will its supersonic successors survive the harsh Martian environment?
With missions to Mars and Titan, is NASA betting the future of planetary science on nuclear-powered drones?

NASA’s March 2026 Supersonic Rotor Tests Unlock 30% More Lift for Next-Gen Mars Helicopters
Overview
In March 2026, NASA successfully tested supersonic rotor blades in a simulated Martian atmosphere, achieving tip speeds beyond Mach 1.08 without structural failure. These advanced rotors generated 30% more lift than previous subsonic designs, overcoming Mars' thin atmosphere that demands high rotor speeds to produce sufficient lift. Two rotor designs were evaluated: the efficient long-bladed SkyFall rotor and a three-bladed system with higher lift capacity. Building on this breakthrough, the SkyFall mission, planned for December 2028, will deploy six autonomous helicopters via a novel mid-descent release, carrying scientific instruments for wide-area reconnaissance. Rigorous testing and collaboration underpin this mission, which paves the way for future Mars exploration and aerial technology on other worlds.
