Engineers at NASA’s Jet Propulsion Lab make a breakthrough in rotor technology. Testing shows rotor blades won’t disintegrate when they spin at supersonic speed. SkyFall helicopters preparing for deployment on Mars. The team pushed rotor tip speeds to Mach 1.08, boosting the Mars vehicle’s lift capability by 30 percent. This breakthrough allows future missions to support heavier scientific payloads, including advanced sensors and larger batteries for extended flight.
