Is reproduction possible in space? People are looking for an answer to this question a long time ago. During Soviet times, rats were sent across the Universe. It so happened that all experiments were performed on these rodents. Pregnant rats gave fully viable offspring, though they themselves soon died. And the rats, returning to Earth, experienced difficulties with movement, because they were formed in conditions of weightlessness. In the entire history of space exploration, it has been visited by many animals. Dogs and monkeys saw Earth from orbit earlier than man. After the French even sent the cats. And turtles, for example, became the first animals that circled the moon.

So why all these experiments? They had to answer the main question - is it possible to reproduce people in space. And some time ago, an answer was received ...

NASA experts regret to state that the dreams of people about conquering and settling distant planets are still unfounded. Without special anti-radiation protection on a spacecraft, people will not be able to multiply.The proton particles attacking the human body sterilize the female embryo conceived in space and make the unborn child incapable of reproduction. Scientists have concluded that in the ovaries of a girl conceived during a space flight, all immature eggs will die - they are formed approximately at the fifth month of pregnancy. That is, such a girl can never have their own children. In addition, radiation affects the quality of male sperm - high-energy particles and radiation damage male sperm cells, so children conceived in space may have genetic defects.

The main damaging factors in outer space are charged particles flying from the sun and cosmic radiation from other sources. In particular, high-energy protons and heavier ions (up to iron) that can damage DNA are distributed in space. Modern spacecraft can not completely save astronauts from these particles.

Given that the journey into the depths of space can take dozens and hundreds of years, any such mission will end, barely beginning.“The radiation protection that we have today will not allow us to multiply,” say specialists in radiation biophysics. DNA, which is necessary for the development of every cell in our body, is particularly sensitive to the type of radiation found in space. Experiments on laboratory animals have shown that ionizing radiation kills the ovum of the female embryo in the second and third trimester.

“The conquerors of space would have to try very hard to save the embryo's eggs during pregnancy, so that the girl was not sterile and reproduction did not stop in the colony,” experts say. However, mankind is still far from breeding in space, because even modern astronauts are strictly forbidden to establish any kind of relationship with each other than professional ones.

Mars is the nearest planet to which a manned expedition can head for the foreseeable future. On its surface, the radiation level is already low enough to conceive, but scientists are advised to create underground bases for additional protection. The best place for long-term living and breeding people, researchers called one of the craters of the Martian moon Phobos, said the portal Space.com.Inside the crater, the level of cosmic radiation hazardous to humans is reduced by 90 percent compared with open space.

True, the researchers hope that this problem can theoretically be solved. Scientists emphasize that the current technology of building spacecraft does not provide reliable protection against proton particles, but in the future science may develop quite effective coatings.
