Obviously, enough people settled on the planet. Now he rushes into space to other planets, other worlds. Me some time ago, suddenly puzzled question that, maybe, the desire to space as it is genetically built into the human population. Give this thought to those who insist on the theory of extraterrestrial origin of life. Perhaps this is an argument in the dispute. Life originated in space and was for the planet entered, so man tends back. The truth is, other living creatures, tearing at the limits of Earthly comfort I do not know.
One way or another, but wanting to hit the road for a week not in Komarovo, and the ISS, among the millionaires abound. It is a pity that the station still more and to carry back only the tourists are not going. Today for money on the ISS managed to get only five people. The other fly to work. This is a troublesome thing – busy with tourists, but as it turned out very favorable.
Space, generally, requires a lot of money. Considering that not every person can afford to buy a car, it to deal with space transportation passengers can afford not every rich country. Probably, for this reason, we seek cheaper ways of delivering goods or passengers to low earth orbit. Continue reading
“Our observation was aimed at studying the chemical composition of the comet Tempel 1,” says Michael Mumma (Michael Turner) from space flight Center NASA Goddard (NASA Goddard Space Flight Center). The Mumma and his colleagues used a powerful telescope, the Keck Observatory in Hawaii for a detailed analysis of the light emitted by the gas of the comet at the moment of impact. Since each type of atoms and molecules has its own characteristic frequency of radiation, on the basis of this, scientists were able to determine the chemical composition of the comet’s nucleus.
Comets are blocks, which consist of ice and dust that move in elongated orbits. It is believed that the nucleus of the comet is gas and dust formations, remaining after the formation of the main bodies of the solar system.
When approaching the Sun, its radiation heats the comet’s nucleus, releasing dust and gas. The latter form a coma (cloud around the nucleus) and one or more tails. Repeated heating leads to the fact that disappear from the surface of the substance having a low boiling point. In fact, the nucleus of a comet is formed “crust” that is different chemically from its internal regions. This makes it difficult to determine the true composition of the comet just by studying the gas in its tail. Continue reading
The earth is the home of humankind. Can be considered and the Solar system. After all, we already went to the moon, our spacecraft has reached other planets. It would seem that about the area of Land we need to know everything.
Actually mankind for decades trying to unravel such close and such mysterious phenomena. Describe below of the top ten mysteries of the Solar system.
The Oort Cloud. The main issue regarding this site is that whether there is any? This is perhaps the chief mystery of our Solar system. Scientists have suggested the existence of clouds only hypothetically, but this piece of the Universe no one has seen. The theories then formed comets with long orbital period. Scientists can only assume that the Oort cloud is at a distance of 50-100 thousand.e. from the Sun. The bounds of this object lying on the very edge of the Solar system. The billions of bodies are from the cloud is bound by gravity to the Sun. Continue reading
