Prolonged stay in microgravity lead to health problems — fact. For example, people have known that during the flight to Mars, astronauts will be able to experience a wide range of medical problems, including muscle atrophy, lack of calcium, a deterioration of the cardio-pulmonary system, impaired vision, and even impaired immunity. Researchers from Michigan Hospitals, Henry Ford completed this list, another problem was proved that weightlessness destroys the joints, which are not reversed even after the return to Earth.
The study was headed by head of the Department of musculoskeletal genetics Jamie Fitzgerald. The disposal of the team of scientists turned the data gathered when submitting inside the unmanned Russian satellite BION-M1 six male mice into Earth orbit — they were there from 19 April to 19 may 2013. At the time of takeoff these rodents were between 19 and 20 weeks, and the Ground was the same mouse, but kept in conditions of normal gravity.
Analysis of tissue and cartilage have shown that the absence of gravity after 30 days in mice caused symptoms of osteoarthritis. The researchers explained that even if the mice are trained and perform active movements, their body lacks the burden which there is in earthly terms. According to Jamie Fitzgerald, in terms of gravity, necessary to maintain the health of joints the load can be obtained even during normal walking.
The worst thing is that after returning to Earth, the cartilage is restored with great difficulty — most likely, astronauts and space tourists will experience health problems for a very long time.
