This hemispheric view of Venus was created using radar observations, including images from NASA’s Magellan spacecraft. Magellan imaged more than 98% of Venus. Gaps in the Magellan coverage were filled with images from the Earth-based Arecibo radar. The composite image was processed to improve contrast and to emphasize small features, and was color-coded to represent elevation. Magellan launched on May 4, 1989, and was deployed from the cargo bay of Space Shuttle Atlantis on May 5, 1989. The spacecraft orbited Venus from August 10, 1990, until October 13, 1994 when the spacecraft was commanded to plunge into the atmosphere of Venus. Image credit: NASA / JPL-Caltech / USGS.
