At the science Museum in London opened a major exhibition “Cosmonauts: Birth of the space age”. It was to be the culmination of the cross year of Russia and great Britain, but now the British authorities have given guarantees for the return of Russian exhibits. Including artifacts that have never left the walls of private enterprises: the Soviet space ships, outfits, and archival documents. Tickets for the show sold out two months in advance.
This moment in London waiting for: when the world’s first woman astronaut will come to the machine in which it 52 years ago, spent almost three days, circling above the Earth.
“It’s such a faithful and reliable friend, by which without emotion could not be disregarded. And in the training center, when I meet him, every time I try to pet him and say “Hello!””, – says Valentina Tereshkova.
Spacecraft “Vostok-6” was never exported outside of Russia – like most of the exhibits of the exhibition dedicated to Soviet and Russian achievements in space exploration. A significant portion of what is now presented in the London Museum of science, and even Russia have seen a few. Continue reading
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
Periodic comet attracted by the Sun, sent to him, but pass due to the same sensitivity to the solar wind, which causes the surrounding cloud of dust and gases blown away from the Sun. People believe that the tiny particles of solar wind will impact more than large particles, but this assumption is wrong. If this were so, then how to explain the continued existence of the Asteroid Belt, which includes debris of any size is not affected, apparently, by the solar wind. The small object may lose velocity faster than the larger object because of differences in gravity, but if they are sensitive to solar wind, it occurs the same effect, – they are repelled equally. The comet, which (eventually) reach the Sun, with a very repeatable trajectory around the Sun, losing a lot of water vapor so that the ratio of substances in their composition is aligned at the expense of pushing away by the solar wind. In short, they lose their cover. They fly up with acceleration from the external space, but at this time do not change direction, going outside, and face (with the Sun). In fact, comets complete their orbits, coming nearer in the process, getting closer and closer to the Sun. Continue reading
