NASA Might Be Sending a Balloon to Mars' Biggest Moon

NASA is looking into the possibility of sending a quadcopter to explore Titan, the largest of Mars' moons, according to the space agency.

NASA agreed to put $100,000 toward a preliminary study of the aircraft. The quadcopter, also known as a quadrotor helicopter, would be carried by a giant balloon in order to travel quickly and unobtrusively to Titan's surface to study it. Larry Matthies, a senior research scientist at NASA's Jet Propulsion Laboratory, submitted the proposal for funding in March. The study is expected to start in July, and wrap up by April 2015.
