The main problems during space flight are considered motion sickness, fatigue, dehydration, loss of appetite and back pain
The astronauts can perform on the International space station not more than six months. And for good reason.
The loss of muscle and bone mass in zero gravity during this time is so great that the continued presence in space for humans is not possible.
Future space tourists will not go through the same tough training as cosmonauts and astronauts – how flying can affect their health?
In an article published by the British medical journal, argues that the district doctors in British clinics need to be prepared for the fact that in the near future, their patients will begin to wonder whether their body to move space travel.
Only a handful of doctors have sufficient knowledge in the field of space medicine to give expert advice. Continue reading
Inessa Kozlovskaya of “Space flight: living in zero gravity”
“Space flight: living in zero gravity”.
Gravity existing on Earth for millions of years, has contributed to the development of all life on Earth organisms and invade their system of life as a factor contributing to their successful functioning in the gravitational field of the Earth. Opening up opportunities to systematically study the impact of eliminating gravity, spaceflight facilitated the accumulation of information and facts that contributed to the development of the theory on the role and place of gravitational mechanisms in the various body systems and the development of a new physiological science — gravitational physiology.The most gravity-dependent system of the body is the propulsion system, in which gravity has played such an important role that today we have the right to determine its evolution as the evolution of the struggle of living organisms with gravity wrestling success ended in mammals the development of a strong skeleton, strong muscular system, management systems movements, and information systems able to ensure the perfection of movement in complex conditions of the gravitational field and its izmeneny.

Flight to Mars, flight to Mars how far is Mars how to fly to Mars, mission duration to Mars
The planet Mars is one of the brightest objects in the night sky. Like a bright red star, it is visible to the naked eye in the night sky. Approximately every two years, Mars and Earth reach their closest point, called “opposition”. At this point, the distance between Mars and Earth is about 55 million kilometers. Almost every two years, the scientists take this opportunity to send to the red planet spacecraft. So how long does it take the spacecraft to reach Mars?
The total time of flight from Earth to Mars varies from 150 to 300 days, depending on the speed of launch, the position of the planets, the route and the amount of fuel on Board.
The first spacecraft to reach Mars was Mariner 4. The device was launched on 28 November 1964. On Mars he arrived on 14 July 1965, where he successfully made a series of 21 Photos. Continue reading
