The development of China's manned space technology has aroused great concern around the world, and now the launch time of the Shenzhou 18 spacecraft has been determined, and the selected astronaut lineup will be fully unveiled, and 6 people will be in orbit at the same time, and the handover will be live broadcast on the space station, and the new spacecraft will be fully prepared for takeoff, and the Shenzhou 17 spacecraft will be ready to return.
Manned space science and technology is a feat of human space technology, which has a bearing on the civilization process of all mankind and is a high-tech means for exploring the deep space universe.
The mainland's Shenzhou-17 astronaut crew is expected to return to Earth in late April, and it seems that the time is getting closer and closer. So after returning to Earth, what discoveries can the Shenzhou-17 spacecraft report to the motherland and the people, and what progress and achievements will it bring back?
According to the analysis of netizens, the astronauts returned to Earth by the return capsule, because the volume and space area of the return capsule are limited, and there may not be too many samples that can be brought back to the earth at the same time, because compared with carrying more scientific samples, ensuring the personal safety of the astronauts and welcoming them back to the motherland safely is what the country attaches more importance to, and it is also what the people are looking forward to.
Therefore, the design of the return capsule is to give priority to ensuring the safety of astronauts, and then to return with a small number of scientific research samples when possible.
This explains that when the Shenzhou spacecraft returned to the capsule several times, when they returned to the earth smoothly, when the astronauts left the capsule, they basically did not carry anything, so netizens thought that the astronauts really would not bring things back from space? Of course not, after all, they went to space to work in order to carry out scientific research projects that were not suitable for progress on the earth.
Even if there is only a limit to what you can bring back from space, you have to pick the most important thing to bring back. In March this year, the astronauts of the mainland's Shenzhou 17 retrieved the space module from the outside of the space experiment module with test samples that had been placed outside the capsule for one year, and such samples were a variety of materials, and the total amount was also considerable, as many as 407, including metal materials.
The purpose of this experiment is very important, because the purpose of this experiment is to see how different materials on the earth change after being left naked in the space environment for a year, including many new materials in recent years, and composite materials used in the construction of bases on the moon in the future. For example, lunar soil reinforcement materials, gel composite lubricating materials, etc., and some special copper metal materials.
These experimental samples are very valuable, and after being placed outside the capsule in the space environment for more than a year, the samples must be retrieved for analysis and comparison, so that rigorous and precise conclusions can be drawn to see which materials are more suitable to play an important role in the construction of lunar research and development bases in the future, which materials can be used for what purposes, and can be more useful in space.
At the same time, if these materials have undergone the placement of the space environment, what changes have occurred, what are the impacts of these changes on the use on the earth, and which industries will bring potential opportunities.
And so many materials, in the end, is there a material with super stability, even if it is placed in space for so long, it still resists space radiation and does not change, so whether this material can be used to build a better space shelter, or materials such as thermal insulation of the base, as well as important construction materials that block radiation, etc.
These samples need to be brought back to the earth, after careful analysis and laboratory testing by scientists, to obtain further accurate conclusions, and the scientific research significance and value of these samples are also priceless and precious, not only related to the process of China's aerospace science and technology, but also for the human aerospace research and development, has played a positive role in promoting.
This research alone can see the precious significance of the space station built by the mainland, and the priceless contribution to scientific research will affect the future destiny of mankind.
Through the data of these materials brought back from space, the scientific research experts of the mainland are likely to have more inventions and creations, and will also bring new support and ideas for breakthroughs in some fields, which can provide more suitable conditions.
These materials include not only special new materials, but also radiation cooling materials, optical fiber materials and high-tech optical thin film materials, which have been carried out in the continental space station in May this year.
Then after the future Shenzhou-18 spacecraft is in orbit, a new batch of astronauts will continue to conduct extravehicular material tests, and this project will continue.
In order to further analyze various materials, increase the richness of material types, and the scientific nature of experiments, there are progress in other research projects such as life medicine and medical topics, as well as the progress of space planting, seedling cultivation, etc., I believe that the astronauts will report on the progress of these scientific research projects after they return.
The launch time of Shenzhou-18 has been determined, and more remarkable progress will be made in the field of scientific research. At that time, as long as the weather, temperature and various comprehensive conditions are met, it will be launched as expected, and the majority of netizens are looking forward to seeing the live broadcast of the spacecraft and the successful flight to orbit and the space station.
