Is it a dream to organize a space family?

With the increase of population on the earth, space is an attractive living space. Therefore, human beings are determined to conquer the universe and emigrate to space. When the Clementine probe launched by NASA discovered that there was water on the moon, and the lunar probe further confirmed that there was water on the moon, mankind accelerated the pace of developing the universe. The United States, Japan and other countries have planned to build factories, tourist bases and lunar cities on the moon, and even immigrate to the moon at an appropriate time. Especially after the American Mars Pathfinder successfully landed on Mars on July 4, 1997, the United States put forward an ambitious space exploration plan. 2/kloc-0 At the beginning of the century, a group of astronauts were sent to explore Mars, which lasted nearly 1000 days.

With such a grand space undertaking, the stay time of astronauts in space flight will inevitably be greatly extended. Therefore, a very realistic problem is raised: these large number of astronauts need husband and wife to live together and raise children together long after they leave the earth. Then, can male and female astronauts organize families in space, even get pregnant, give birth and raise the next generation?

Astronauts believe that it is a difficult problem for male and female astronauts to organize their families and raise their children in space, which has long been valued by scientists. The former Soviet Union was the first to study this problem. As early as the 1960s, the former Soviet Union's biological satellite sent mice into the sky to "get married" and let female mice get pregnant and have children in space. The experiment was successful. However, in the case of weightlessness in space, the bones of young mice are fragile, easy to break and their muscles are slack. Later, scientists in the former Soviet Union specially designed a "centrifugal weighting device", which replaced gravity with centrifugal force generated by the high-speed rotation of the squirrel cage, thus effectively overcoming the adverse effects of weightlessness in space.

The United States is also stepping up its experimental research work in this area. They have sent male and female kangaroos to the space laboratory one after another and let them "get married" there. As scientists expected, these male and female kangaroos can live, get pregnant and give birth safely in space, and give birth to new life.

Kangaroo is a mammal close to human beings. The experiment of kangaroo "getting married" in the sky has successfully found the way for human beings to organize their families in space, but it cannot be said that all the problems of human beings organizing their families in space have been properly solved, and human beings have their own special feelings and needs.

For example, in order for male and female astronauts to organize families in space, it is necessary to consider whether women can adapt to long-term space life like men. Practice has proved that female astronauts can stand the test of special space environment. 1964, the former Soviet female astronaut Tereshnikov took off in the "Dongfang VI" spacecraft, which was the first time a woman flew into space. 1in June, 983, Sally Ride took off and became the first female astronaut in the United States to go into space. By the end of 1997, there were 24 women working in space in the United States, many of whom carried out missions in space many times. Among them, Shannon Lucid set a new record for women to stay in space orbit 187 days on the "Peace" space station. Especially in 1992, American astronaut couple Li Pingbin and Devis also launched together, completing a family-style space flight.

2 1 century will be an era of great achievements in the space industry. Astronauts' space journey will be long, lonely and arduous. Moreover, because women are as competent as men in space flight, officials in charge of the space industry in the United States and Russia claim that they are currently considering the issue of letting male and female astronauts fall in love in space and form a space family. Many astronauts are also eager to take the lead in organizing space families. American astronaut Foucault has expressed his willingness to go to Mars for a 1000-day space flight, and asked to go to Mars with his wife to write a new chapter in human space navigation.

However, from the perspective of space life science, space medical scientists believe that the influence of long-term weightlessness in space, a large number of cosmic rays, high-energy particle radiation and high vacuum and high clean environment cannot be ruled out.

Then again, can male and female astronauts organize families, pregnancy and childbirth in weightlessness in space? After years of research, Russian biologist Sherova believes that space activities do not affect the reproduction of life. On the other hand, American scientists are very cautious. They believe that the space experiment of human life science is an important practical activity of space life science, so we should not rush into it, and we should make careful arrangements, not to mention many difficulties to overcome. But they believe that at the beginning of this century, with the development of space industry and the joint development of space activities around the world, the progress of human space life science will be accelerated. After the successful development of a long-term life support system that can ensure astronauts to sail safely in space for several years, it will be completely possible for male and female astronauts to work, fall in love and have children in space. It is no longer a distant dream for human beings to organize their families in space!

The birth date of "space baby" will not be too far away from us!
