Venus Express arrives

VenusThe European Space Agency’s Venus Express space probe – the first unmanned spacecraft to closely examine the second planet from the sun since the late 1970s – arrives at the planet to undertake a detailed study of the atmosphere, the unusually symmetrical cloud patterns of the planet’s north and south hemispheres, as well as observing the massive, hurricane-like vortices which remain over the poles. Venus Express also looks for the source of traces of sulphur dioxide in the Venusian atmosphere, which could be a sign that of active volcanoes on the surface.
