April 12 – Day of aviation and cosmonautics

On April 12 the whole world celebrates Day of aircraft and Astronautics.

This is a special day – a day of triumph of science and all those who are today engaged in the space industry.

Russia marks cosmonautics Day in commemoration of the first space flight by Yuri Gagarin. The holiday was established by decree of the Presidium of the Supreme Soviet of the USSR dated 9 April 1962.

April 12, 2010 isposed 49 years since the first flight of man in space. And did it our compatriot Yuri Gagarin. 108 minutes spent in space opened the way for other space explorers. For a short period of time since the first flight into space man has visited the moon, explored almost all the planets of the Solar system, but the first flight was the most difficult and dangerous.

But the confidence and optimism, the desire to conquer space overcame all obstacles. Addressing all the inhabitants of the Earth before launch on April 12 1961 Yuriy Alekseevich said, “Dear friends, relatives and strangers, countrymen, people of all countries and continents! Continue reading

The origin of the solar system

The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .

Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.

Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.

The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available.

Outside the Solar system,on the contrary, or due to the large number of large heavenly bodies, or because of the excess water formed a huge body, surrounded by natural satellites. Continue reading

TASS: Space – the Comet Churyumov

Comet Churyumov-Gerasimenko with the module “Fily” reached the nearest point to the Sun

Apparatus “Rosetta” was launched into space in March 2004 with a spaceport in Kourou to study the comet 67P/ Churyumov-Gerasimenko. To the destination apparatus has arrived in 2014 and is currently in orbit around the comet. November 12, 2014 on the surface of the investigated object was launched module “Fily”. He entered the history of space exploration, as the first probe successfully landing on a comet for the first time and managed to drill the surface for the taking of soil samples. Thanks to this unique scientific mission scientists expect to obtain detailed data about the physical and chemical structure of the comet, which will greatly expand human knowledge about the origin of the Universe.

According to him, the closer to the star in recent months, the comet’s activity has steadily increased. This is evidenced by the comparison of Photographs taken by Rosetta, the robot lander with a difference a year last summer and now. Continue reading
