- Magellan found that at least 85% of the Venusian surface is covered with volcanic flows. The spacecraft’s data suggested that despite the high surface temperatures (887 degrees Fahrenheit or 475 degrees Celsius) and high atmospheric pressures (92 atmospheres), the complete lack of water makes erosion an extremely slow process on the planet.

One of the most successful deep-space missions, Magellan was the first spacecraft to image the entire surface of Venus and made several discoveries about the planet. Even as it plunged into the Venusian atmosphere and burned up, it was still collecting data.

In October 1994, the Magellan spacecraft intentionally plunged to the surface of Venus to gather data on the planet's atmosphere before it ceased operations. It marked the first time an operating planetary spacecraft had been intentionally crashed.
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 2, 2024 · The astronauts deployed Magellan and its upper stage on their first day in space, sending the spacecraft on its 15-month journey to Venus. Following its arrival at the cloud-shrouded planet, Magellan spent four years mapping Venus in unprecedented detail, vastly increasing our knowledge of the planet.
NASA's Magellan spacecraft made a dramatic conclusion to its highly successful mission at Venus when it is commanded to plunge into the planet's dense atmosphere Tuesday, October 11, 1994.
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.

On August 10, 1990, Magellan encountered Venus and began the orbital insertion maneuver which placed the spacecraft into a three-hour, nine minute, elliptical orbit that brought the spacecraft 295-kilometers from the surface at about 10 degrees North during the periapsis and out to 7762-kilometers during apoapsis.
