Qin Xianan agency issued photo Beijing, September 14 Jiuquan Xinhua (reporter Zhang Su) for Tiangong-1 is expected to fall and other issues, deputy director of the manned space engineering office Chinese Wuping today introduced, until now, Tiangong-1 expects the second half of 2017 will fall, after serious analysis, most of Tiangong-1’s structure components will be destroyed in the fall of the ablation process. Cause of aviation and ground damage probability is very low, the risk is very low. September 14th, the Jiuquan Satellite Launch Center held a press conference, a spokesman for the space lab and rocket development, loading and task preparation. At the press conference, a reporter asked: in March this year, Tiangong-1 formally terminated data service. Please introduce the current situation of Tiangong-1, is expected to fall? Whether it will cause harm to the safety of the ground and aviation activities fall? Wu Ping introduced in March 16th this year, Tiangong-1 officially ended the target aircraft data service, fully completed its historic mission. Tiangong-1 launched in September 29, 2011, has 6 times in orbit during the rendezvous and docking with the Shenzhou eight, No. nine, No. ten spacecraft, completed the task, it should be said to make a very large contribution to Tiangong-1 for Chinese manned space development. Wu Ping introduction, Tiangong-1 design life for two years, the actual work in 4 and a half years. Until now, Tiangong-1 is still in our continued close tracking and monitoring, the whole structure is complete, the orbit is at an altitude of 370 km, and is the attenuation speed of 100 meters per day, expected in the second half of 2017 will fall. Wu Ping introduced, after careful analysis, most of Tiangong-1’s structure components will be destroyed in the fall of the ablation process, cause of aviation and ground damage probability is very low, the risk is very low. Wu said that as a responsible big country, the Chinese government has always attached great importance to the research and management of various types of space debris. Since 2000, Chinese began to implement special plan for space debris, a lot of work in the space monitoring, protection, early warning, mitigation and emergency cooperation, launched a long march rocket final passivation disposal, abandoned satellites orbit disposal of space debris mitigation actions. Wu Ping introduction, a long time before the launch of the long march seven launch vehicle in this regard to design and consideration, such as the passivation process for the two, after the launch of the tank into the exhaust gas, to avoid explosion. Long march seven.相关的主题文章:
