Solar system

Solar system is the planetary system that includes the Sun. and all the objects orbiting it – planets, moons, asteroids. comet. a large number of meteoroids, gas and cosmic dust .

But how was Solar system formed? The universe formed through the Big Bang. There is the Big Bang theory, which says that long ago the universe was small and hot lump. Suddenly it exploded, expanded space, the temperature of the particles decreased considerably. Due to the force of gravity began to gather clouds of matter, the result of which was formed all the galaxies and stars. It took about 8 billion years after the Big Bang, before the Solar system was formed. The matter is unevenly distributed in space and began to attract the dust and gas. Formed dust and gas clouds, they eventually formed star, the Sun. From other particles of the cloud formed other objects.

Components of the Solar system are divided into categories:

1. Planet

3. Small body

The center of the Solar system is the Sun . It accounts for almost all of the bulk system – 99,87 %. Continue reading

The principle of operation

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

Long-term manned space missions is now impossible

The answer to the question of how in the coming years will be Russia’s contribution into the process of full exploration by the inhabitants of the Earth, not yet clear

Before the first manned flights into space, many physicians feared that in weightlessness the astronaut may be a different disease: ulcers and kidney stones, sudden weight loss, softening of bones, decreased muscle tone, the development of sea-sickness, disturbance of the orientation and other misfortunes. But in reality it turned out that astronauts in General are more or less able to adapt to microgravity and not to experience any serious discomfort, especially in flight conditions, the duration of which does not exceed 6-10 months. In order to reduce harmful effects to a minimum, the astronauts, while in orbit, exercise, diet, etc.

But how will affect the human body long-term space flight, lasting several years, physiologists have collected insufficient data.

In light of the active conversations and different messages about the future of manned human flight to Mars, which include the experiment “Mars-500” and recent statements by President Barack Obama . this information is very necessary. Continue reading
