The global surface of Venus was first mapped by the Magellan orbiter during 1990–1991 with 50 km spatial and 100 m vertical resolution. During three orbit regimes, the surface images were transmitted back to the Earth.

The Soviet Union sent a series of probes to Venus between 1961 and 1984 as part of its Venera program (Venera is Russian for Venus). Ten probes made it to the surface, and a few functioned briefly after landing. The longest survivor lasted two hours; the shortest, 23 minutes.
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.

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.
