    NASA will send a small helicopter to Mars as part of the space agency?s 2020 mission to place a next-generation rover on the Martian surface, marking the first time such an aircraft will be used on another world.

    The remote-controlled Mars Helicopter, designed to take flight in the thin Martian atmosphere with twin counter-rotating blades, weighs about two kilograms, with a fuselage the size of a softball, NASA said. Its blades will spin at almost 3,000 rpm, roughly 10 times the rate employed by helicopters on Earth.

    NASA officials said the rotorcraft will reach the Red Planet?s surface attached to the car-sized rover. After placing the helicopter on the ground, the rover will be directed to drive to a safe distance to relay commands. Controllers on Earth will command the helicopter to take its first autonomous flight after its batteries are charged and tests are conducted, NASA said.

    The helicopter is intended to demonstrate the viability and usefulness of such aircraft on Mars, NASA said, with potential roles as a low-flying scout or to reach locations inaccessible from the ground.

    NASA said it plans a 30-day flight test period that will include up to five flights, starting with a short vertical jaunt to hover for about 30 seconds at an altitude of 10 feet and progressing to flight distances up to a few hundred yards and durations up to 90 seconds. The helicopter contains solar cells to charge its lithium-ion batteries and a heating mechanism to keep it warm during frigid nights.
