Discoverer: named after Edmund Halley opening date: 1758 (first predicted perihelion) Alternate designations: comet Halley (Halley), 1P Orbital characteristics: Age: 2449400.5 (17 February 1994) Aphelion: 35.32.e. Perihelion: 0.586.e. The semi-major axis: 17, 8 and.e. The eccentricity repulsed: 0, 967 Orbital period: 75, 3 and the Inclination of the orbit to the Ecliptic plane: 162, 3 degrees Last perihelion: 9 February 1986 Next perihelion: 28 July 2061 g the Period of revolution around the Solar system: from of 74.4 to 79.2 years. The average value of 76 years. Thanks to a successful “visits” in 1986 to comet Halley spacecraft “VEGA-1 and VEGA-2” (USSR) Giotto (ESA), “Suisei” and “Sakigake” (Japan) scientists got the first pictures of the core and comprehensive information:

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
