Aboard the International space station that is circling around our planet, the cosmonauts and astronauts conducted various scientific studies and experimentsto understand how long the effects of weightlessness and space radiation affect living organisms. Why? Then, that already in the relatively near future humanity can base their first extraterrestrial colony on the moon and Mars. Such plans include, for example, Russia, USA and China. However, the possibility of the establishment of permanent extraterrestrial colonies, we need to determine perhaps an even more important question. You need to understand how in the space to give birth.
For all the existence of Astronautics flew into space more than 60 women. But not one of them during these flights was not in the position and certainly did not give birth in microgravity. As would be childbirth in space? In a conversation with Business Insider on this issue decided to answer evolutionary biologist Scott Solomon from rice University (Texas, USA).
Like childbirth in space will be different from birth on Earth?
The most obvious difference birth in space from the birth on the Earth will be their complexity. In experiments, scientists have found that long-term exposure to space weightlessness reduces bone density. Research returning to Earth after long months of stay in space, astronauts show that the density of their bones each month was reduced by about 1-2 percent. This is very bad news for future space women who decide to bear children naturally through birth pains. At the time of birth of their hip bones will weaken so much that the birth process can break.
After a natural birth on Earth mothers make an effort, thus helping faster child to be born. In weightlessness that would be problematic, says Solomon. In addition, the scientist notes that children who are born in conditions of weightlessness, such as on Board spacecraft, the skull is too large to woman able to give birth naturally. The reason is that the child’s body in the process of growth will adapt to extraterrestrial conditions of gravity.
To address the issue, according to Dr. Solomon, in the course of delivery technology will be used cesarean section is a medical operation in which a newborn is removed through an incision in the uterus.
Big head will not be the only distinction between earthly and cosmic children. People born on other planets will change the color of the skin. On Earth from exposure to space radiation magnetic field protects us. On the same Mars and moon conditions are quite different. People are exposed to thousands of times greater doses of cosmic radiation than on Earth.
The body can respond appropriately by giving people new skin pigment. To counter the UV rays on the Earth the human body uses melanin, in other species it is responsible for the carotenoids. The inhabitants of Mars over many generations can develop a totally different pigment, which would enhance their protection against radiation. For more on this, you can read in our previous article.
In the end, says Solomon, life on other planets will lead to the fact that people evolyutsioniruet and will greatly differ from earth.
