The History of Venus

Introduction: Venus is commonly thought to have experienced a transition, within 1 billion years of its formation, to its current highly desiccated state from a wet, more Earth-like past [1]. The assumption of similar origins rests mostly upon cosmogonic arguments. However, it is possible that stochastic differences in the late phases of accretion could have left the " twin planets " with unequ...

The Geology of Venus

The nature of the surface of Venus is one of the keys to answering fundamental questions about the origin and evolution of the terrestrial planets and is of critical significance to comparative planetology. The last 25 years of solar system exploration have provided unprecedented views of the Earth, Moon, Mars, and Mercury. These views have shown that the smaller terrestrial planetary bodies (t...

Of the Venus Ionosphere

• A two-dimensional, time-dependent, shock capturing single-sp•ies (O +)hydrodynamic odel of the Venus ionosphere, which solves the coupled continuity, momentum and energy _,•ons for the altitude range of 150 500 km and the solar zenith angle range of 0O 180 ø has been developed and is presented in this paper. It was again demonstrated thathe introduction of topside heat inflows leads to calcul...
