Space – the theme is interesting in itself. Reflections on uncharted planets, sometimes very different from ours, phenomena that are impossible on Earth due to certain properties of the planet, which can be interesting. It is possible that some of the above below you will find new and interesting, something you did not know about the cosmos. The influence of the environment in space per person has not been fully explored. But research conducted on astronauts indicate the presence of some space sickness, which is manifested in the form of nausea, loss of orientation in space, headaches almost all the astronauts. According to some, it is because of information from noise propagating radio waves in outer space. In addition, there are signs of loss of calcium in the bone, swelling of the face due to improper distribution of body fluids in a vacuum, atrophy muscles, digestive problems and heart rhythm. Do you still want to go to Tito's footsteps and become a space tourist? In the weightlessness astronauts growth slightly increased by reducing the pressure on the spine.

The development of an organism, also, is different than on Earth. This was proved experimentally in rats sent into orbit during pregnancy. Appearing infants had severe abnormalities. In orbit is not familiar day and night – greeted the astronauts 16 sunrises a day. What gets to sleep and disrupts circadian rhythms of the body. Being in a vacuum without a spacesuit deadly.

Despite the exploits of movie heroes, no breath help – just the lungs explode from the pressure difference. For all time of space travel were killed 18 astronauts. But there was no death in orbit: the tragic incidents have occurred either at startup or during the descent apparatus. Astronauts have to use liquid substitutes for salt and pepper. Attempts to use our usual spices in a dry form resulted in obstruction of ventilation with unpleasant consequences. Returning astronauts must again learn to walk and use cutlery. They call it the "second birth". Been in space, astronauts say that the most difficult to get used to the behavior of abandoned in a vacuum objects.
