I must say that the problem of space distances increasingly asserting itself. Chemical rockets on its effectiveness has exhausted itself for the future. Even the nearest planets of the Solar system on them to fly extremely long. Nuclear space engines while not in orbit, but on paper. Ion on a large scale. The spacecraft with solar sails will be valid only within the Solar system.
What engine to fly to the stars and how? After all, even with a nuclear engine will take flight for decades and centuries! Why? Because, according to theories, it is impossible to exceed the speed of light. And by estimations of astronomers, the nearest star to Earth with exoplanets (a planet similar to earth) is at a distance of 13 light years.
It is about exoplanet Kapteyn b, which is presumably suitable for life. For those who do not know: for light year, the astronomers believe the distance that a beam of light passes in our earth year at the speed of 300,000 kilometers per second. Other discovered exoplanets: Gliese 832c (16 light years), Gliese 667 Cc (22,7 light years), Kepler 186f (500 light years), Kepler 62f (1200 light years). But on a normal ship flight to the nearest star to us (alpha and Proxima Centauri – the distance in four and a half light years) will take time-75 thousand years. Of course, not light, but ordinary, earthly years. Continue reading
At the Institute of biomedical problems started the experiment on simulation of a manned flight to Mars in the framework of the international project “Mars-500”.
The participants, six people will spend 105 days in a special complex, which will simulate a space ship. The experiment will include studies associated with the study of the proteome – the set and of the functioning of the human proteins. In particular, scientists will study the effects of extreme conditions on proteins.

In the experiment “Mars-500” does not play study on the effect of factors such as weightlessness and increased radiation levels.
Scientists will study the effect of prolonged hypokinesia on the mineralization of bone. For this purpose the camera will be used in the peripheral scanner. Participants also will experience a special garment, created with the use of nanotechnology. Continue reading
