The Magellan Venus Radar Mapping Mission

Abstract: The NASA Magellan Venus Radar Mapper spacecraft was launched into an interplanetary transfer trajectory to Venus on May 4, 1989, and will be placed into orbit around Venus on August 10, 1990. The orbiter carries a 12-cm-wavelength, multimode radar system. In the synthetic aperture mode it is capable of imaging most of the Venus surface at a resolution of better than 300 m, approaching 120 m over more than half the planet. In the altimeter mode it will determine topographic relief to a vertical accuracy of bett… Show more

“…Brown et al, 2004). After the Pioneer Venus Orbiter spacecraft's radar altimeter allowed for the earliest topography of Venus, albeit with a 150 km surface resolution (Masursky et al, 1980;Pettengill et al, 1980), Magellan's 12.6 cm radar wavelength data gave better views of the impact craters on the Venusian surface (Saunders et al, 1990). It also revealed a surprising paucity of craters on Venus, indicating a younger surface than previously suspected.…”

“…In addition, during the extended missions, multiple incidence angle data will be acquired over given areas. The reader is referred to Saunders et al (1990) for more details, although it should be clear that the order of magnitude increase in resolution as compared to existing data, the calibrated nature of the data, and the variety of coverage will significantly increase our understanding of the nature of the venusian surface. Specifically, MAGEL-LAN data will provide detailed views of surface morphology, estimates of elevation, and the ability to separate reflection coefficients from roughness, that cannot be determined from existing data.…”

“…We describe here in detail the major geographic, geologic and tectonic features observed, discuss their similarity to features observed in other parts of Venus, develop preliminary interpretations on the nature and relationships of the observed features and assess the age of this part of the planet on the basis of the characteristics and distribution of craters of probable impact origin. The MAGELLAN mission is scheduled to acquire high resolution image and altimetry data of the region north of about 75" S during its nominal mission (September, 1990to May, 1991 (Saunders, et al, 1990). The data and interpretations in this paper provide a synthesis and framework for the understanding of the nature of major features and processes in this region.…”
