Teams of astronauts may soon start work on the International Space Station is not for 6 months, as before, and for the year, according to the news agency RIA Novosti.
First annual expedition will be experimental and will not until 2015 to carry out a test mission will select two players - one a Russian cosmonaut and a NASA astronaut. If all goes well, than will be considering a one-year term for expeditions to the ISS on a regular basis.
Federal Space Agency over the years has repeatedly stated his desire to try to experiment on human long stay in space, like the mission "Mars-500" when the European Space Agency and Roscosmos in 2010-2011. Simulate on Earth to Mars mission duration of 500 days.
NASA researchers also believe that six months on the ISS astronauts in weightlessness, are consistent with the maximum duration of stay in space for future members of the expedition to the Red Planet, and that special tests with increased length of stay at the space station are, strictly speaking, unnecessary.
But they both agree that the first annual mission will assess the impact of long-term stay on the ISS on the health of astronauts.
However, this mission will not set a record for the length of stay of man in space - Russian cosmonaut Valery Polyakov spent more than 437 consecutive days at the space station "Mir" from January 1994 to March 1995
