NASA attaches autonomous mini helicopter to Mars 2020 rover mission

The Mars 2020 rover will carry a mini helicopter to Mars, protected by a cover during landing. Once a suitable area is found, the helicopter will be deployed to conduct test flights. It features a mini camera for capturing images of the Martian surface. The helicopter is small, weighing under four pounds, with rotor blades that spin at 2,400 RPM, allowing it to fly up to 15 feet high. It includes a solar array to recharge its batteries, which power the blades and keep it warm at night.
