    The fifth and final current proposed Automated Transfer Vehicle (ATV) of the European Space Agency will carry the name "Georges Lemaître". The Belgian theologian and astrophysicists is considered the founder of the Big Bang theory. ESA's space freighter represent an important contribution to supply the International Space Station.

    The unmanned European space freighter, the Automated Transfer Vehicle, short ATV, called, represent an important contribution of the European Space Agency to supply the International Space Station. After the end of the space shuttle flights last year they play in maintaining the operation of the ISS an even more important role. Otherwise, the ISS can currently be controlled only by Russian space ship and a Japanese freighter.

    The first, launched in 2008, ATV was named by the French science fiction writer Jules Verne. The following space freighter were then named after Europeans who have played an important role in science and technology with their visions. Launched last year, ATV-2 carried the name of the German astronomer Johannes Kepler ATV-3, which is to be launched in March, is called "Edoardo Amaldi" and is therefore named after an Italian physicist and space pioneer. The ATV-4, which is scheduled to start next year, is named "Albert Einstein".

    The name "Georges Lemaître" for the fifth and last of the initially planned ATV was proposed by the Belgian ESA delegation and approved at a meeting in Paris this week by the delegates. "Belgium was the European space adventure from the beginning an important fellow," said ESA Director General Jean-Jacques Dordain following the decision. "By naming ATV-5 by Georges Lemaître, we honor a Belgian scientist of world-class, whose work has contributed significantly to expand our knowledge of the origin of the universe."

    Georges Lemaître was born in 1894, studied mathematics and physics and a PhD in 1920. Three years later he was ordained a priest. After living in Cambridge, Harvard and the Massachusetts Institute of Technology (MIT), he returned to Belgium and in 1925 professor at the Catholic University of Leuven. In 1927, he discovered solutions of Einstein's field equations which arise not static, but an expanding universe. Lemaître also provided a first estimate of the Hubble constant, which describes this expansion. The idea of ​​an expanding universe would later become famous for the Big Bang theory.

    The Automated Transfer Vehicle bring on every flight around six tonnes of supplies for the International Space Station. Stay for up to six months docked to the space station and then - loaded with trash and unneeded objects - specifically to crash, so they burn up in the Earth's atmosphere.
