Synthetic Aperture Radar (SAR)
- 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).

NASA's Magellan mission to Venus was one of the most successful deep space missions. It was the first spacecraft to image the entire surface of Venus and made several discoveries about the planet. Magellan burned up about 10 hours after being commanded to plunge into the Venusian atmosphere.

The Magellan spacecraft, which arrived at Venus in 1990, made the first global map of the surface of Venus as well as global maps of the planet's gravity field.
May 6, 2019 · On Oct. 13, 1994, after a series of controlled engine firings lowered its orbit, Magellan entered Venus’ atmosphere and burned up, having completed its highly successful mission during more than 15,000 orbits of the cloud-shrouded planet.
The Magellan spacecraft was a 1,035-kilogram (2,282 lb) robotic space probe launched by NASA on May 4, 1989. Its mission objectives were to map the surface of Venus by using synthetic-aperture radar and to measure the planetary gravitational field. [2]
NASA's Magellan spacecraft used a sophisticated imaging radar to make the most highly detailed maps of Venus ever captured during its four years in orbit around Earth's sister planet from 1990 to 1994. After concluding its radar mapping, Magellan also made global maps of Venus's gravity field.
May 6, 2019 · Magellan’s high-resolution radar global map of Venus, comparable in resolution to visible light imagery-based maps of other bodies in the solar system, provided scientists with a deeper understanding of Venusian geology and the role of meteorite impacts, volcanic activity, and tectonics in the formation of surface features.
