NASA agreed to put $100,000 toward a preliminary study of the aircraft. The quadcopter, also k**wn as a quadrotor helicopter, would be carried by a giant Balloon in order to travel quickly and u**btrusively 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.
