Cosmonautics. To Mars! For youth (2017)

After a year-long experiment with the participation of American astronauts, the Kelly twin brothers, one of whom spent a year on the ISS, and the other was observed here on Earth all this time, scientists came to the conclusion that in long-term space expeditions, the human body can get younger.

A person has been flying into orbit for more than half a century, however, scientists do not know everything about how space affects the body, and this is very important for flights to Mars and other planets.

In addition to the advantages of rejuvenation, there are many disadvantages in long-term expeditions: astronauts lose their eyesight in orbit, experience calcium deficiency and muscle atrophy.

But the main question is rather psychological, because astronauts miss not only their loved ones, but also their home planet as a whole.

However, all these issues can be solved.

The problem of cosmic radiation is still the most difficult.
