NASA says it plans on landing a helicopter on Mars. The space agency said Friday it will send a small helicopter to the Red Planet as part of NASA's 2020 mission to put a new land rover on the Martian surface. The Mars Helicopter will be remote-controlled and weigh about four pounds with a fuselage the size of a softball. NASA's Jet Propulsion laboratory says because of Mar's light atmosphere, the small helicopter should be able to fly up to 100-thousand feet above the Martian surface.
