Venus Express (VEX) is the first exploration mission for Venus, the second planet from the Sun, orbiting it every 224.7 Earth days, of the European Space Agency, often stylized as “esa,” is established in 1975, an intergovernmental organization dedicated to the exploration of space, currently with 19 member states.
Launched in November 2005, it arrived at Venus in April 2006 and has been continuously sending back science data from its polar orbit around Venus. Equipped with seven scientific instruments, the main objective of the mission is the long term observation of the Venusian atmosphere. The observation over such long periods of time has never been done in previous missions to Venus, and is key to a better understanding of the atmospheric dynamics. It is hoped that such studies can contribute to an understanding of atmospheric dynamics in general, while also contributing to an understanding of climate change on Earth. The mission is currently funded by ESA until December 31, 2014.
