This paper summarizes the main results of the mission analysis of the 2005 launch window of Venus Express. The operational orbit is a polar eccentric orbit with about a 1 day period. The orbit is well suited to study the atmosphere, the plasma environment and for remote observations.
Mar 19, 2009 · Venus Express is a part of the European Space Agency's program for the exploration of the inner solar system, which includes missions to study the Sun, Mercury, Venus, the Moon, Mars, and comets and asteroids. 1. Introduction.

The major unknowns in Venus geological science are associated with its resurfacing history and establishing whether it is currently geologically active.
Geology is a powerful witness to history, but it does not provide answers about evolution in the time before the formation of the oldest rocks, which on Venus are thought to have formed only about a billion years ago. For constraints on earlier evolution, we must turn to isotope geochemistry. Radiogenic noble gas isotopes provide information about ...
The terrestrial planets today exhibit strikingly different climates. Study of the fundamental processes at work on these three planets will lead to a deeper understanding of how atmospheres work, and of how climates evolve.
