Magellan orbits Venus

In 1990, the space probe Magellan arrived at its planned polar orbit around Venus. As the planet rotated slowly beneath it, Magellan circled once every 3-hr 15-min, collecting radar images of the surface in strips about 17-28 km (10-17 mi) wide and radioed back the information. Magellan was carried into space in the shuttle cargo bay of STS-30 Atlantis, launched 4 May 1989, and was the first planetary spacecraft to be released from a shuttle in Earth orbit. The Magellan mission also provided gravity, atmospheric and other measurements. On 11 Oct 1994, it was directed towards the surface, collecting data until it broke up and partially vaporized in the atmosphere.«
