Space station by 2020, China will be built in orbit Ultra 10 | the space station _ news

Original title: space station by 2020, China will be built in orbit Ultra 10

[Trans World Airlines reports] spokesman said of the China manned space engineering, will be held next year in the first half of this year, organizing the implementation of manned space lab mission, which is expected to launch second space laboratory in the third quarter of this year and be completed around 2020 China's space station construction mission.

On March 11, the national people's Congress, the Chinese Academy of Sciences on space applications Center for engineering and technology senior consultant, academician Gu Yidong told the global times, a journalist, said in an interview, is about to launch tiangong second temple on the first that are currently in orbit a space laboratory, the basic scale, but "compared with the temple on the first, more formal Temple on the second. Space is primarily target aircraft, first Shenzhou spacecraft and docking, in this process, the rendezvous and docking techniques to test, and successfully applied. On the temple on the second, these technologies are used to including space science and application experiments. On this basis, the astronauts will reside a longer time in the temple on the second, and carried out many scientific experiments, number and range of the experiment more than on the temple. ”

Reference to the temple on the first, Temple on the second and the differences between the completed space station by 2020, said Gu Yidong, the space station is a new stage, Temple on the first, Temple on the second major development is in many ways technology, gain experience and prepare for the construction and operation of the space station. He said, the space station is a brand new system, laboratory and space have a very big difference. "Space laboratory is a single cabin, 8 tons, used to support the short-term human participation in space activities. Three segment of the space station docking to be a combination, each cabin is 20 tons. They need to develop large rockets, only big rocket successfully, it is possible to launch space station segment, thereby building a space station. "At the same time as the astronauts on board the space station to stay longer, so they need more training, to accumulate more experience.

"Space station larger load payload capacity is relatively strong, will run on the track more than a decade. Arrangement of the space station project more, has identified several science and applications and themes involving the applications of space science and most of the areas, such as space life sciences and biotechnology also in several directions in space microgravity science, including fluid science experiments in microgravity conditions, combustion science, space materials science experiments, basic physics experiment. In addition, space astronomy, space physics and space environment research and Earth observation from space, the study of Earth system; others are experimental, cutting-edge technology. ”

中国空间站预计2020年建成 将在轨运行超10年|空间站_新闻资讯

　　原标题：中国空间站预计2020年建成 将在轨运行超10年

　　[环球航空报道]中国载人航天工程新闻发言人近日透露，将于今年中至明年上半年间，组织实施载人航天工程空间实验室任务，其中预计于今年第三季度发射天宫二号空间实验室，2020年前后完成中国空间站建造任务。

　　3月11日，全国人大代表、中国科学院空间应用工程与技术中心高级顾问、中国科学院院士顾逸东接受《环球时报》记者采访时表示，即将发射的天宫二号与当前在轨运行的天宫一号都属空间实验室，基本规模差不多，但“与天宫一号相比，天宫二号更为正规。空间一号主要是作为目标飞行器和神舟飞船进行对接，在这个过程中，交会对接技术得以检验，并成功应用。在天宫二号上，这些成熟技术就被用来开展包括空间科学和应用的实验。在此基础上，航天员在天宫二号上将驻留更长的时间，同时开展很多科学实验工作，实验的数量和范围比在天宫一号上开展的更多。”

　　提及天宫一号、天宫二号以及在2020年建造完成的空间站之间的区别，顾逸东介绍说，空间站是一个全新的阶段，天宫一号、天宫二号主要是在多方面发展技术、积累经验，为建造和运行空间站做准备。他表示，空间站是一个全新的大系统，和空间实验室有非常大的区别。“空间实验室是单舱段的，8吨左右，用于支持短期有人参与的空间活动。而空间站由三个舱段对接后成为一个组合体，每个舱段都是20吨级。所以需要发展大火箭，只有大火箭研发成功，才有可能发射空间站的舱段，从而建造空间站。”同时由于航天员在空间站上停留的时间更长，因此他们需要更多的训练、积累更多的经验。

　　“空间站规模更大，装载有效载荷的能力也比较强，将在轨道上运行十年以上。所以空间站安排的项目更多，已经确定了若干个科学和应用的方向和主题，涉及空间科学和应用的大部分领域，比如说空间生命科学和生物技术；同时在空间微重科学方面分了几个方向，包括在微重条件下开展流体科学实验、燃烧科学实验，空间材料科学实验、基础物理实验。此外还有空间天文、空间物理和空间环境研究，以及从太空对地球观测，对地球系统进行研究；还有一些前沿技术实验等。”
