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

New space ships of the USA and Russia

New ships Russia: Soyuz TMA-MS, Progress MS, PCA and PTK NP Rus.

New ships USA: Cygnus, Dragon, CST-100, Orion.

Existing ships of Russia: Progress M, Soyuz TMA-M.

Existing ships of the United States: no.

Signus together with Soyuz TMA-M

Soyuz TMA-MC is a Russian multi-seater spacecraft for flight in earth orbit.

New upgraded version of the spacecraft “Soyuz TMA-M”. The update will affect almost every system of manned spacecraft. The first launch is planned no earlier than 2016.

The main points of the program of modernization of the spacecraft:

the energy-conversion efficiency of solar cells, will be enhanced through the use of more efficient Photovoltaic cells;

the reliability of rendezvous and docking of spacecraft with the space station due to the change in engine installation of the mooring and orientation. 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
