A European project to study Venus and understand the Earth

How and why Venus and Earth similar and identical twins, they have experienced a different trend also? A team of planetary scientists will conduct the investigation in the context of a three-year mission, EuroVenus, which will be in particular to atmosphere and winds of Venus.

"Venus probably still has many secrets to reveal," said Thomas Widemann of the Observatory, which is coordinating the project.
The six laboratories will be involved in this project and those are France, Belgium, Germany, Portugal and the United Kingdom, it will extend the Venus Express mission of the European Space Agency (ESA) continuing operating its data and conducting simultaneously observations from ground-based telescopes such as ALMA, Chile.

Launched in November 2005, Venus Express is the only satellite in orbit around Venus. Its mission was extended upto June 2015, when a huge amount of data remain untapped.

EuroVenus, The project should enable Europe to assert its “leadership” for the study of this planet, estimated Thomas Widemann. A Japanese probe could enter and orbit around Venus in 2015, for his part, said Colin Wilson (University of Oxford, UK).

Often improperly called “evening star” Venus is formed at the same time and in the same region as the Earth, probably from similar materials. It has a similar size to Earth: 95% of its diameter and 80% of its mass.

Yet, while the Earth is home for lives, Venus is now an inhospitable planet. It is dry as a rock and it prevails in its atmosphere, composed mainly of carbon dioxide, a greenhouse intense raises its surface temperature to over 450 ° C.

For planetary scientists, understanding the long-term of these planets sister, is “a major key” in the approach to new planets will be discovered outside our solar system, these “exoterres” potentially favorable to the development of a form of life. Would they Lands in power, or conversely become Venus?

EuroVenus will seek to better understand the atmosphere of Venus, which has variations “that do not correspond to physical laws” established by scientists.

Study program in particular, a phenomenon that always intrigues the research community, the winds on Venus. As the world moves round on itself in 243 days, the atmosphere revolves around it at a speed 50 times, completing a full rotation of the planet in just 4-5 days.

Called “super-rotation” This phenomenon, the mechanisms are still not understood, “is also tipped to the atmospheres of Earth-like exoplanets in very slow moving,” said the Paris Observatory.

EuroVenus brings together researchers from the Paris Observatory, the Observatory de la Cote d’Azur, the Institute for Space Aeronomy of Belgium, the University of Cologne, University of Lisbon and the University of Oxford.
