Radar guns were catching speeders back home, but near Venus the Magellan probe was putting radar to more creative ends: using it to map the cloud-shrouded surface of Venus at 300-foot resolution. The simulated colors in this 1991 view are based on pictures of the Venusian surface from Russia's Venera 13 and 14 landers. Brighter colors highlight mountainous regions; darker colors represent relatively smooth areas resulting from lava flows or meteorite impacts.
