When Chang 'e V went to the moon at the end of last year, she also brought seeds. Now these rice seeds have been harvested, and the rice grains are one centimeter long.
But has anyone ever thought that seeds will mutate after a trip to heaven, and what about our astronauts? What will happen to humans in heaven? Will they become monsters?
The United States is a country that developed space earlier. Many astronauts have been to the sky, and 12 astronauts have also landed on the moon. In 20 19, scientists from NASA inspected Scott who stayed on the International Space Station for 340 days. They found Mark, a twin brother with the same gene, for gene comparison and found that Scott's "immune system and DNA repair function" had a mutation. From a genetic point of view, this is irreversible permanent damage.
Before this, astronauts who have gone to heaven have also been found, and their bodies will have other abnormalities.
An obvious phenomenon is that astronauts will grow about five centimeters tall after staying in the sky for a period of time. This kind of "welfare" is the envy of many short people. On the earth, due to the action of gravity, human beings will be suppressed by their own gravity, but in the universe, under weightlessness, the musculoskeletal body will become slack, the gap between joints will increase, one joint will increase a little, and dozens of joints of the body will "relax" together, which will naturally produce obvious effects.
But don't worry about happiness, "growth" comes at a price. More than half of the astronauts will have spinal pain, and their height will recover after returning to earth, and they are more prone to symptoms such as disc herniation.
In addition, muscle atrophy and osteoporosis are very obvious. According to NASA's records, some astronauts have lost 20% of their muscle mass in the 1 1 day while working on the International Space Station. It is really stressful and light, and bones and muscles become useless and unconsciously degenerate because of weightlessness.
In addition to the body, astronauts also have blood problems.
During an ultrasonic examination, the astronauts of the International Space Station found that among the 1 1 astronauts of the space station, 5 had jugular vein blood flow stagnation or moving back and forth, and 2 of them had retrograde blood flow.
They found that the blood in the jugular veins of the two astronauts actually began to flow in the opposite direction, from the heart to the head. Scientists described this symptom as "extremely abnormal". Scientists on the ground agree that this may be caused by a blocked blood vessel somewhere. As a result, the blood changed direction. Sure enough, in the later scan, they found blood clots in their bodies, which is a symptom of thrombosis.
An American professor also analyzed the causes of death of seven American astronauts who landed on the moon and found that three of them died of cardiovascular diseases, with a high proportion. However, due to the small sample size, it is impossible to draw any conclusions.
The professor irradiated the experimental mice with the same radiation as the moon for 6 months, and the experimental mice also developed similar atherosclerotic cardiovascular diseases, which was very similar to the experience of astronauts.
Because blood and other liquids have no stable gravity in the body, these liquids will also float to the head, which will also cause problems such as swelling of the optic nerve, slightly flat eyeball and decreased vision.
It is not easy to train every astronaut. China has a population of over one billion and dozens of astronauts. The training process of each astronaut not only costs a lot of money, but also a good astronaut is hard to find. If you treat them as treasures, you can't let them get hurt in space.
In the early years, we developed the space industry without the guidance of others, and we could only explore it step by step. Some data of NASA mentioned above used to be confidential, but it was no secret until the improvement of space technology in various countries in recent years. However, Yang Liwei, the first space hero in China to carry out manned space mission, was injured in this groping process. When he returned to Earth, his face was covered with blood and he never went to heaven again.
In the past, China's space flight was a short trip, and it came down in a few days. Even if you are slightly unwell, you can recover after a few days' rest. But now that China has its own space station, it is normal to stay in the sky for several months, so the health of these astronauts must be considered.
Before Shenzhou-12 docked with Tiangong Space Station, Tianzhou cargo spacecraft had already delivered a large package of materials. In addition to 120 kinds of space delicacies, there is also a space bike that is very eye-catching, which is an important tool to deal with muscle atrophy in space environment.
In addition to strengthening exercise, there is now a solution to blood coagulation in space. Scientists have developed an antithrombotic solvent, which astronauts need to inject to prevent blood coagulation.
In addition, astronauts need to receive professional medical training before entering space. Usually they can solve their own skills such as tooth extraction and wound suture. Astronauts are usually equipped with cardiac defibrillators, first aid kits, medical books, ultrasound and physiological saline on the space station.
If you really encounter an unsolvable problem, the doctors on the ground will be on standby at any time and give remote guidance to solve it. Every space flight is inseparable from tens of thousands of staff on the ground.
People only see the scenery of astronauts in the universe, but few people can see the price paid behind them. China can become a space power without the efforts of these astronauts and countless behind-the-scenes staff. They are people worthy of our respect and stars we should chase.
