Magellan: Initial Analysis of Venus Surface Modification

Creators: Arvidson, R. E.; Baker, V. R.; Elachi, C.; Saunders, R. S.; Wood, J. A.

Abstract

Initial Magellan observations reveal a planet with high dielectric constant materials exposed preferentially in elevated regions with high slopes, ejecta deposits extending up to 1000 kilometers to the west of several impact craters, windblown deposits and features in areas where there are both obstacles and a source of particulate material, and evidence for slow, steady degradation by atmosphere-surface interactions and mass movements.
