Possibly, comets brought water to Earth
To see exactly what is in the comet, it is necessary to analyse its substance with the help of different high sensitive devices, bringing samples to Earth. But aboard a small spacecraft such devices are difficult to place, because the size of the station Stardust 1,7×0,7×0,7 meters – about the same size as the Desk. How to take a sample of matter, flying from the comet’s nucleus at high speed? Space standards Stardust was moving slowly relative to the comet, about one and a half times slower than fly around the Earth artificial satellites. However, even this speed was several times greater than that of the bullet, the station flew over one second 6 km from the Contact of dust particles with the container of solid material at this speed (more than 20 thousand km/h) would have led to their strongest heating and evaporating. The only way to mildly catch and stop these dust particles, turned out to be a trap made of unique material – aerogel, which was established in 1931, but the big distribution has not received.

The copy of the diaries of one of the founders of the Soviet cosmonautics Vasily Pavlovich Mishin shared with the descendants of American designer, businessman
Rare cosmic rarity — the diaries of Soviet space technology designer Vasily Mishin returned to Russia. Seven years ago an American businessman Ross Perot bought his diaries of the author, and now, 7 years later, I decided to share them with the Russian public, passing a group of our scientists copy the relic. They translated the diaries presented today at the United rocket and space Corporation.
Academician of the Russian Academy of Sciences, Hero of Socialist Labor Vasily Mishin took the helm of special design Bureau (OKB-1) after the death of Sergei Korolev in 1966, the year. He led a major space company until 1974. In the box of his victories — involvement in the successful launch of the first Intercontinental missile R-7 in August 1957, the launching into orbit the first artificial Earth satellite on 4 October 1957, the first manned flight into space on 12 April 1961.

Much does it cost to fly in space?
Previously the space was the subject of dreams and the destiny of only the elect, now to experience weightlessness or take a journey to the stars almost everyone can have money. To replace professional the orbit space tourism comes. Those wishing to become astronauts does not scare nor a long period of preflight preparation or high risk, so every year this extreme form of recreation is becoming increasingly popular .
Weightlessness for all
The “budget” option space tourism is a program of suborbital flights, in which the ship goes into orbit, the aircraft goes to higher altitude (about 100 km), which is a while, and then falls down, whereby passengers can enjoy all the delights of weightlessness.
Suborbital flights is the near future of space tourism, says academician of the Russian Academy of cosmonautics named after K. E. Tsiolkovsky Alexander Zheleznyakov. According to him, now several companies (Space Adventures, Another day universe and Virgin Galactic – ed.) are developing aircraft with such a dynamics that one can say that in 2014 will begin to be more or less regular flights.
