The mapping of Venus refers to the process and results of human description of the geological features of the planet Venus. It involves surface radar images of Venus, construction of geological maps, and the identification of stratigraphic units, volumes of rock with a similar age. Satellite radar provides imagery of the surface morphology by ...
Its mission objectives were to map the surface of Venus by using synthetic-aperture radar and to measure the planetary gravitational field. [ 2 ] 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, and the first spacecraft to test aerobraking as a method for circularizing its orbit.
Magellan was designed to use a Synthetic Aperture Radar (SAR) to map 70% of the Venusian surface down to a resolution of 390 to 985 feet (120 to 300 meters). The basic bus was assembled using spare parts left over from various prior missions including Voyager, Galileo, Ulysses, and Mariner 9.

During the part of its orbit closest to Venus, Magellan's radar mapper imaged a swath of the planet's surface approximately 17 to 28 kilometers (10 to 17 miles) wide. At the end of each orbit, the spacecraft radioed back to Earth a map of a long ribbon-like strip of the planet's surface captured on that orbit.
May 6, 2019 · During this time, NASA was planning its own mission called the Venus Radar Mapper, later renamed Magellan, with the capability to map the planet down to a resolution of 120 meters using SAR. Magellan’s prelaunch goal was to map up to 70% of the planet during one 243-day imaging period, equivalent to one Venusian “day.”.
The Magellan radar sensor, shown in Figure 5-3, is composed of 17 units racked in a 1.5 x 0.9 x 0.3-meter (5 x 3 x 1-foot) enclosure and weighs 154 kilograms (340 pounds). Most of the units are in a redundant pairs for higher reliability. The sensor is located within the spaceraft's FEM and is used in combination with the high-gain and ...
