Magellan (Venus probe)
The primary objectives of the Magellan mission were to map the surface of Venus with a synthetic aperture radar (SAR) and to determine the topographic relief of the planet. At the completion of radar mapping 98% of the surface was imaged at resolutions better than 100 meters, and many areas were imaged multiple times. Other studies included measurements of surface altitude using radar altimetry and measurements of the planet's gravitational field using precision radio tracking. The mission was divided into "cycles," each cycle lasting 243 days (the time taken for Venus to rotate once under Magellan's orbit).
