"NASA's Mars Helicopter: New Design Tested on Earth for Continued Experiments"

NASA's Ingenuity helicopter continues to make test flights on Mars, surpassing expectations with 66 flights and providing valuable data for future aircraft designs. Meanwhile, on Earth, NASA is testing new rotor blades for potential use in future Mars helicopters. The blades, made of carbon material and longer than Ingenuity's, have reached speeds close to the speed of sound. The tests aim to find the right balance between speed and control to support bigger and more complex helicopters.
