The bombardment of comets

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.

Space flights cause a failure in the immune system of a person

The results of two studies of NASA, recently published in the journal journal of Interferon & Cytokine Research suggest that spaceflight may cause temporary changes in the immune system of crew members who are long time on Board the International Space Station.

Data obtained at an early stage of one of the experiments showed that the distribution of immune cells in the blood of crew members during the flight remained relatively unchanged. However, they found that some cell functions were significantly reduced, while the activity of another cell type, on the contrary, increased. That is, in a sense, the immune system of crew members, it failed.

If the cell activity is suppressed, the immune system cannot adequately react to threats, which can lead to asymptomatic for the virus. If activity is increased, the immune system becomes too sensitive, which can lead to the development of allergic reactions and persistent rashes, as well as reported some of the crew members.

In another study, scientists analyzed blood plasma, measuring the concentration of cytokines – proteins that regulate the immune system. Continue reading

The Museum of COSMONAUTICS.

The state Museum of the history of cosmonautics named after K. E. Tsiolkovsky (GMIC) was opened in Kaluga on 3 October 1967, Thus he became the world’s first Museum devoted to its exposition about the history of space exploration. For over thirty years in the Museum of systematic work on the collection, preservation, scientific study, historical heritage in the field of history and practice of space research in our country and abroad.

The actual history of the Museum began in 1936 when the first anniversary after the death of the great Russian scientist, Konstantin Tsiolkovsky. the founder of theoretical cosmonautics, the Creator of the cosmic philosophy, in his home in Kaluga was opened the memorial Museum in his name. This Museum, which is a real pearl of Russian culture from 1967, became a division of the Museum of the history of cosmonautics. The grave of the great Russian scientist with a monument above it is far from main building GMIC.

The initiative to create the Museum of cosmonautics in Kaluga was owned by the outstanding scientists of our time: Sergei Korolev, A. N. Tupolev, A. A. Blagonravov, I. P. Bardina, L. I. Sedov and others. Continue reading
