The world day of aviation and cosmonautics

The history of the holiday

There are achievements that humanity can be proud of. The conquest of space, no doubt, belongs to them. 12 April 1961 Soviet cosmonaut Yuri Alekseyevich Gagarin made the first orbit around the Earth. In 1962, the first anniversary of manned flight into space, was signed a government decree about establishment in the USSR of a new holiday, cosmonautics Day.

Of course, the conquest of space is a celebration of not only national, but international significance. So 7 years later, in 1968, the General conference of the international aeronautical Federation on the initiative of the USSR adopted a decision to establish the world day of aviation and cosmonautics, which is widely celebrated on April 12 in many European countries and the USA.

April 12 – date at all unique to the history of space exploration. On this day, in 1981, made its first manned flight of the American Shuttle “Shuttle”.

The long-awaited event that all of us space community was ten years old, happened in 19.03 Moscow time on 12 November 2014. It is difficult to imagine the average person that the operation occurred at a distance of more than 500 million kilometers from Earth!

For the first time in the history of space exploration module “Philae” the European space Academy reached the nucleus surface of comet 67P /Churyumov-Gerasimenko and landed.

This is the first and incredibly complex operation in the history of science, when the artificial origin sat down on the comet. The difficulties were in the fact that moving a celestial body has an unusual shape. The comet is named after its discoverers – the Soviet scientists-astronomers Klim Churyumov and Svetlana Gerasimenko in 1969.

This comet belongs to the short – period body- it rotates around the Sun at a considerable distance, and therefore has no tail, and its trajectory crosses the orbits of Jupiter and Mars. The trajectory of rotation of the comet 67P has changed, it is influenced by the proximity of Jupiter.

Scientists claim that this celestial body appeared about 4.5 billion years ago, its agreement measures approximately 3 by 5 km. the First Photographs of the comet Churyumov-Gerasimenko were made in March 2003, with the help of which scientists have been able to build a three-dimensional image.
