Speaking of space exploration and flight operations to other planets, not only our solar system, but also outside of it, a person forgets that he, in fact, integral part of the Earth. And how our body will lead for outside the native blue planet, and which in general will arise problems in space exploration are still unknown.
Although you can even guess how. Not by chance Russian cosmonauts joked at one time that a pencil in orbit is much more useful than memory, because they noticed that the latter begins there to malfunction in their work. And this is still in the orbit of the Earth, and what talk about flights to other planets …

Problems of space exploration by man
NASA is currently conducting a long-term experiment in attended by astronauts – unicellular twin brothers Scott and Mark Kelly. The first spent the whole year on the ISS, and the second at that time lived quietly on Earth. Please note that NASA employees are not looking at Scott returning from the international space station, do not rush to conclusions, stating that the final results can be expect only in 2017.
However, researchers in many countries have long been studying this a problem, since development will largely depend on its development astronautics on earth. And science still cannot give an answer even to the question, how long can a person stay away from Earth, not to mention many others.
First, a person cannot exist for long without the habitual Earth gravity, and while this problem in space exploration is not resolved. Secondly, modern technology cannot protect astronaut from exposure to radiation and other cosmic radiation, which literally permeate everything and everyone. Cosmonauts on the ISS, for example, even with their eyes closed, “see bright flashes” when these rays act on their optic nerves. But such emissions permeate the entire human body in space can affect the immune system and even DNA. Moreover, any protection the astronaut automatically becomes a source of secondary radiation.

The effect of space on human health
Researchers at the University of Colorado recently surveyed mice that spent two weeks in orbit (aboard the shuttle Atlantis). Just two weeks! And for this short time in the body rodents unpleasant changes occurred, they all returned to Earth with signs of liver damage. Before that, Professor Karen notes Jonsher, space researchers did not even suggest that he was disastrous for the internal organs of everything living on Earth, including including for a person. It is no accident that astronauts often return with orbits with symptoms similar to diabetes. Of course, on Earth they are here heal, however, what will happen to a person with prolonged stay in space, and even far from the home planet? Will it fully solved the problem of the influence of space on man?
By the way, scientists are constantly interested in such a question – conception and reproduction in space, as long as people’s plans are long-term, or even lifetime flights to other planets. It turns out in conditions zero gravity eggs, for example, are divided quite differently, that is, not two, four, eight, and so on, but two, three, five … For human is tantamount to lack of conception or interruption pregnancy in the earliest stages.
True, the other day, Chinese scientists came up with a “sensational statement “that they managed to achieve the development of the embryo mammals in microgravity. And although the article is a journalist Cheng Yingqi sounds ambitious – “The giant leap in science – embryos grow in space, “many researchers reacted to this information is very skeptical.

Disappointing results regarding the development of the Great Space man
So, if you take stock without even waiting for the results NASA experiment with twin astronauts can be done disappointing conclusion: humanity is not yet ready for flights in deep space, and it is still unknown when this will happen. Some researchers even argue that we are not even ready for flying on The moon (from here we can conclude that Americans never go there flew), not to mention Mars and other grandiose space plans.
Ufologists, in turn, insist on no less authoritative the opinion of other scientists that overcoming the cosmic space, as we are going to do now, is a dead end way. In their firm conviction, developed alien civilizations travel in the universe very differently for example using wormholes are temporary spatial holes that allow instantly move to any point of the Divine universe. Perhaps there are more advanced ways that are not available to our understanding. Earth’s space rockets so far only claim to near-Earth orbit development, and exclusively for all indicators ranging from turtle (by the standards of the Great Space) moving speeds and ending with the complete insecurity of the astronauts in these primitive devices …
