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
Unlike planets, comets move on highly elongated orbits, and therefore are visible only at short periods close to the Sun.
The main part of any comet is its nucleus .
According to the hypothesis of the famous American researcher of comets Fred Lawrence Whipple, cometary nucleus is an ice consisting of a mixture of frozen water and frozen gases interspersed with refractory rocky and metallic particles . Figuratively speaking, it looks like a “dirty iceberg”.
Let us imagine that we see the newly opened the comet, which is somewhere in the vicinity of Jupiter’s orbit. Seeing through the telescope hazy pale speck, like a spherical nebula (such unattractive are presented to the observer of a distant comet), we may be disappointed at first. With the approach of the comet to the Sun the solar flux increases. Comet “ice” begin to evaporate rapidly. Around the nucleus formed a vast glowing gas shell – coma. Together with the core of it is the head of the comet. Continue reading
One day in April Gagarin made his flight, and today we are on such a universal scale occasion will transcend time and space.
Time is not linear, reality is relative, and can simultaneously be in two different places. To prove it, in our current cultural ranking, we sort of go back in time to learn about the future. With undying love for “the Martian Chronicles” and warm memories of childhood on the theme of Kir Bulychev’s works we decided this time to make more distant and mysterious space journey, revealing along the way a couple of other unknown planets. So, the first point of our sci-Fi trip -1938 year.
The asteroid Vesta, around the Main asteroid belt
In earth time: 1938
