Long space flights

Russian scientists in collaboration with foreign partners have classified the threats to the health of astronauts during long expeditions, including during the flight to Mars, said “Interfax-AVN” on Monday, the Deputy Director of the Institute of biomedical problems Russian Academy of Sciences Valery Bogomolov.

“Three years ago, with our international partners, we determined the risk matrix and the degree of our knowledge about these risks, the degree of protection. This list is big enough, it about 15 positions,” said Vladimir Bogomolov, commenting on sending to the ISS first annual expedition consisting of Russian Mikhail Kornienko and American astronaut Scott Kelly.

The annual flight of the astronauts arranged, in particular, in order to prepare future long interplanetary flights.

According to the scientist, it is not only about physiological parameters, for example, about the influence of space flight on the cardiovascular system, the motor area or sensory abilities.

“Takes into account such factors as the adequacy of medical supplies on Board the spacecraft for the relief of disease,” – said V. Bogomolov.
