Magellan (spacecraft)
The Magellan spacecraft, also referred to as the Venus Radar Mapper, was a 1,035-kilogram (2,282 lb) robotic space probe launched by NASA on May 4, 1989, to map the surface of Venus by using synthetic aperture radar and to measure the planetary gravitational field.The Magellan probe was the first interplanetary mission to be launched from the Space Shuttle, the first one to use the Inertial Upper Stage booster for launching, and the first spacecraft to test aerobraking as a method for circularizing its orbit. Magellan was the fourth successful NASA mission to Venus, and it ended an eleven-year gap in U.S. interplanetary probe launches.
