The Magellan SAR Venus Mapper space probe is scheduled for Shuttle launch in 1989. The spacecraft will carry a 12 ft high gain antenna to reveal features down to 250 m in diameter and the spacecraft orbit will allow mapping 70 percent of the Venus surface. The SAR will also be used as an altimeter which will permit tracing variations in the gravitational field of Venus in terms of slight variations in the frequency of the radio signals beamed to earth caused by changes in the spacecraft velocity. The launch vehicle will be the Inertial Upper Stage. Images acquired by Magellan, with two orders of magnitude better resolution than the Pioneer Venus Orbiter, will confirm or disprove the presence of live volcanos and active lightning clouds on Venus.
