Venus - The nature of the surface from Venera panoramas

The present investigation has the objective to analyze the information collected by the Soviet Venera 9, 10, 13, and 14 lander spacecraft imaging systems. The analysis is to make a systematic comparison with other planetary surfaces possible, and an improved understanding of the surface of the planet Venus is to be provided. Attention is given to the imaging systems and transformation methods, observations, the observed characteristics of Venera lander sites, and an interpretation of the geological processes responsible for the features observed in the Venera panoramas. It is concluded that the present Venus environment is considerably different in terms of temperature, pressure, and atmosphere composition from the present terrestrial subaerial environment.
