NASA Will Explore Other Worlds Using Drones The space agency announced its plans to explore the Saturn moon Titan using a life-hunting rotorcraft called Dragonfly. The craft is intended to land on Titan by 2034 and spend years gathering data and photos of the frozen moon. NASA will also send a helicopter drone to Mars during the 2020 rover mission. Håvard Grip, NASA, via Space.com The helicopter scout is a small craft that weighs about 4 lbs and carries no scientific equipment. The Dragonfly craft is larger, spanning 10 feet, carries a suite of scientific equipment and a $1 billion price tag. If the crafts perform well, NASA anticipates using such drones extensively in the future.
