我国为何要打造属于自己的空间站?近日,我们中国成功发射的神舟十二号载人飞船首次完成了进入空间站的壮志,意味着我国空间站的正式运转和作业已经步入了倒计时阶段。
所谓的空间站指的是一种在近地轨道长时间运行,可供多名航天员巡访长期工作和生活的载人航天器。目前全世界共有两个空间站,一个是以美国为主导的国际空间站。
二则为咱们中国自己独自建造的天宫系列空间实验室。在上世纪九十年代初,美国提议联合欧美日一些主要的大国共同建造一个多国共享的空间站。
我国曾提出加入这个太空计划,却遭到了美国的制裁。理由很简单,美国一直主导西方世界,对咱们实行高端技术的封锁,自然不可能分享空间站这类顶尖太空科技给我国。
于是,我们便于一九九二年制定打造自主空间站三步走的战略。近三十年过去了,如今我国通过一代航天人坚持不懈的努力,终于即将完成这一太空夙愿。
我们坚持耗费巨大财力、精力来突破西方技术封锁,建造空间站的根本原因有两个,一是基于国际政治形式考核。美国高举所谓意识形态大棒,封堵我国科技进步的嘴脸。
在短时间内不会改变。九十年代初,美国在拒绝对我国开放空间站太空技术后,便敲碎了我们希望能从西方世界引进尖端科技的幻想。
转而下定决心自主研发先进技术。于是九二年提出的打造国产空间站便成为了往后我国发展高科技的里程碑。今天,美国联合欧、日等国对我国百般的技术和贸易打压则很好的反渗出。
出了当年我国不惜一切来搞高科技的路子,有多高瞻远瞩。二则是空间站对我国未来的科技进步有重大意义。在地球的大气层保护之下,人类被束缚住手脚。
有很多科学实验是无法完成的,例如在观测宇宙方面,大气层相当于一层滤镜,许多天体是我们在地面上无法观测到的。但如果将望远镜拿到大气层之外。
情况就得到很大的改善。比如说巡天号的光学舱来对宇宙进行更精确更精细的观察。著名的太空望远镜哈勃望远镜常住在大气层之外。
少了很多地球上的干扰,因此他拍摄到了很多地球上看不清的太空景象。而在材料合成方面,空间站同样具有极高的研究价值。地球上由于重力的限制和。
很多合金材料无法融合在一起,而在处于失重状态下的太空战则不存在这样的问题。美国在太空中做出了多种地球上无法实现的合金,而且太空制造的新型合金具备的强度抗疲劳度、导电率和导热率。
等性能都比地面上加工出来的要强很多。因此在这种层面上讲,太空战的重要性不言而喻。在空间站里还可以合成新的蛋白质和材料。
帮助研发出新的药物,而且人们还可以在空间站中种植植物。因为研究植物在太空中的生长规律,不仅可以为人类在地面上的植物生长研究提供依据。
还能为将来人类移民外太空激烈科学基础。除了对材料植物进行研究,人类还能对宇航员长期处于失重状态,在心理身体指标进行研究,以帮助人类更多的星际探索移民提供科学依据。
由此不难看出,打造一个属于自己的太空空间站,能很好的助力于我国抢得未来高端科技的制胜点。
Why does China want to build its own space station? Recently, China’s successful launch of the Shenzhou XII manned spacecraft has completed its ambition to enter the space station for the first time, which means that the official operation and operation of China’s space station has entered the countdown stage.
The so-called space station refers to a manned spacecraft that runs for a long time in low-Earth orbit and can be used by multiple astronauts to visit and work and live for a long time. There are currently two space stations in the world, one is the International Space Station led by the United States.
The second is the Tiangong series of space laboratories built by China itself. In the early 1990s, the United States proposed to unite some major powers in Europe, America and Japan to build a multi-country shared space station.
China once proposed to join this space program, but was sanctioned by the United States. The reason is simple. The United States has always dominated the Western world and has imposed high-end technology blockade on us. Naturally, it is impossible to share top space technology such as the space station with our country.
Therefore, it is convenient for us to formulate a three-step strategy to build an autonomous space station in 1992. Nearly thirty years have passed, and now, through the unremitting efforts of a generation of astronauts, our country is finally about to fulfill this long-cherished aspiration in space.
We insist on expending huge financial resources and energy to break through the Western technological blockade. There are two fundamental reasons for the construction of the space station. The first is based on the assessment of international political forms. The United States held high the so-called ideological stick to block the face of China's scientific and technological progress.
Will not change in a short time. In the early 1990s, after the United States refused to open its space station space technology to China, it shattered our illusion that we could introduce cutting-edge technology from the Western world.
Instead, he made up his mind to independently research and develop advanced technology. Therefore, the establishment of a domestically-made space station proposed in 1992 became a milestone in the development of China's high technology in the future. Today, the United States and Europe, Japan and other countries have effectively countered China's various technological and trade suppressions.
How far-sighted is the way our country spared no effort to engage in high-tech in the past. The second is that the space station is of great significance to China's future scientific and technological progress. Under the protection of the earth's atmosphere, human beings are bound by hands and feet.
There are many scientific experiments that cannot be done. For example, in observing the universe, the atmosphere is equivalent to a filter, and many celestial bodies cannot be observed on the ground. But if the telescope is taken out of the atmosphere.
The situation has been greatly improved. For example, the optical cabin of the Sky Surveyor provides more precise and detailed observations of the universe. The famous space telescope Hubble often lives outside the atmosphere.
There is a lot less interference on the earth, so he photographed many invisible space scenes on the earth. In terms of material synthesis, the space station also has extremely high research value. Due to the limitations of gravity and on the earth.
Many alloy materials cannot be fused together, and there is no such problem in space warfare in a weightless state. The United States has made a variety of alloys in space that cannot be achieved on Earth, and the new alloys made in space have the strength, fatigue resistance, electrical conductivity and thermal conductivity.
The performances are much stronger than those processed on the ground. Therefore, at this level, the importance of space warfare is self-evident. New proteins and materials can also be synthesized in the space station.
Help develop new drugs, and people can also grow plants in the space station. Because studying the growth laws of plants in space can not only provide a basis for human plant growth studies on the ground.
It can also provide an intense scientific basis for future human migration to outer space. In addition to the study of material plants, humans can also study the mental and physical indicators of astronauts in a state of weightlessness for a long time, so as to help humans provide scientific basis for more interstellar exploration and immigration.
It is not difficult to see from this that building a space station of its own can very well help China grab the winning point of high-end technology in the future.
