Comets fascinate the human mind since ancient people first noticed the white tail streaking through the night starry sky. We remember the date when the comet flies past the Earth once a century or even less often and remember all our lives. In the middle ages in Europe, the appearance of comets was often linked to various natural disasters and diseases. In religion, these heavenly bodies also play an important role. For example, in the New Testament, the comet heralded the birth of Christ.
Astronomers find comets also interesting and fascinating space objects, because they are witnesses of great historical events and even carry evidence of them.
The comet is a relatively small object in our solar system, usually having a diameter of several kilometers. Sometimes called “dirty snowballs” because of their component substances. Usually comets are composed of the following four elements:
Ice (water, ammonia, methane, carbon dioxide)
Some organic materials (e.g., resin)
Rocky ground (optional) Continue reading
Space tourists have already bought vouchers from Roscosmos for millions of dollars, which means that interplanetary travel ceased to be only a figment of the imagination of science fiction writers. Mankind has realized at last that the earth’s resources ischerpaemy, and set his sights on the conquest of the territories on a much larger scale and very different properties. There will be dozens or hundreds of years, and prepapre…our great grandchildren, perhaps when meeting have to introduce myself, “Hey, Hey, I’m from Earth. We got such a strong gravitational field, and there’s somehow easier to breathe”.
Interesting development in this area is the space Elevator, which will allow you to run in a cargo space without using rocket equipment. For the first time this thought Konstantin Tsiolkovsky, and in the twenty-first century NASA is already funding the development of this project. In the future it will be cheaper than building the missiles the media.
In fact, it must be a cable anchored to the Earth’s surface on a moving vessel at one end and the other adjacent to the space station, fixed stationary relatively to the planet. Continue reading
At the Institute of biomedical problems started the experiment on simulation of a manned flight to Mars in the framework of the international project “Mars-500”.
The participants, six people will spend 105 days in a special complex, which will simulate a space ship. The experiment will include studies associated with the study of the proteome – the set and of the functioning of the human proteins. In particular, scientists will study the effects of extreme conditions on proteins.

In the experiment “Mars-500” does not play study on the effect of factors such as weightlessness and increased radiation levels.
Scientists will study the effect of prolonged hypokinesia on the mineralization of bone. For this purpose the camera will be used in the peripheral scanner. Participants also will experience a special garment, created with the use of nanotechnology. Continue reading
