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

Inside the comet 67P found no major voids

Interested in everything connected with high technologies.

Inside the comet 67P/Churyumov — Gerasimenko there are no large voids. The mission of “Rosetta” the European space Agency made measurements that clearly demonstrated and solved the old mystery. Comets are icy debris left over from the formation of the planets 4.6 billion years ago. Spacecraft have visited a total of eight comets, and through these missions we pulled a picture of the basic properties of these space-time capsules. On some questions the answers were found, others appeared.

Comets, as we know, consist of a mixture of ice and dust, and if there were compact, gravity superior to water. However, previous measurements have shown that some of them have very low density, much lower than water ice. Low density means that the comet must be extremely porous.

But what is this porosity: due to large voids in the subsurface of the comet, or due to a more homogeneous structure with low density? Continue reading

The Museum of space history

Review

The history of cosmonautics in the “city of aviation” starts with the building of the Museum. It is an expressive building with a dome, inside which there is the planetarium, one of the outstanding examples of futuristic Soviet architecture. About and imagined future in space at the time. All-Union popularity of the building took on, when his image graced millions of matchboxes Kaluga factory “the Giant”.

To the creation of the Museum of Tsiolkovsky in the 60-ies of the last century had a hand in other space heroes — Gagarin and Korolev. The latter made the most notable contribution: the basis of the collection became the subjects admitted in 1967, from the design office Queen: missiles, propulsion, space vehicles, measuring devices, tools, spacesuits, food warmers. And Yuri Gagarin literally laid the first stone in the Foundation of the Museum — just two months after the first flight into space.

The exposition begins with this event, and from the earliest human attempts to break away from Terra firma. The rocket “the East” is preceded by Chinese gunpowder rockets, and kites, Lomonosov rotary-wing machine, aircraft Mozhaysky and, of course, the works of Tsiolkovsky. Continue reading
