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

“Space flight: living in zero gravity”.
Gravity existing on Earth for millions of years, has contributed to the development of all life on Earth organisms and invade their system of life as a factor contributing to their successful functioning in the gravitational field of the Earth. Opening up opportunities to systematically study the impact of eliminating gravity, spaceflight facilitated the accumulation of information and facts that contributed to the development of the theory on the role and place of gravitational mechanisms in the various body systems and the development of a new physiological science — gravitational physiology.The most gravity-dependent system of the body is the propulsion system, in which gravity has played such an important role that today we have the right to determine its evolution as the evolution of the struggle of living organisms with gravity wrestling success ended in mammals the development of a strong skeleton, strong muscular system, management systems movements, and information systems able to ensure the perfection of movement in complex conditions of the gravitational field and its izmeneny.

Astronomers at the Australian national University has discovered the largest known planetary systems. Therein, except for the Central star has a large planet.
This planet makes a complete revolution around the sun in nearly a million years. This gas giant is at a distance of one billion kilometers from the star, which exceeds in 140 times the distance between Pluto and the Sun. Reported by the BBC.
Thus far, there are only a few of these planetary systems.
The exoplanet, which received the designation 2MASS J2126-8140 has a lot of 12-15 Jupiter. It was discovered in the programme of observations of young stars and brown dwarfs in the immediate galactic environment of the Sun. Astronomers came to realize that they see not two independent object at the same distance from the Sun is about 100 light years away, a planetary system.
“We were very surprised by the discovery of an object with such a relatively small mass so far from the Central star. Unlike Solar, this system could not occur from a huge gas-dust clouds,” says Dr. Simon Murphy from the Australian national University. Continue reading
