The author:(作者)hpmailerpublished in(发表于) 2013/12/2 9:53:41 Chinese designer： Lunar Rover on the moon will not leak， no one can steal
The Beijing News December 2, carrying Chang, third longest launched three-b carrier rocket at the Xichang satellite launch Center. 1:52, arrows separate. Until press time, Chang, third have entered a perigee altitude of 200 km and an apogee of about 380,000 km from earth-moon transfer orbit.
After about 5 days to reach the Moon
According to China's lunar exploration program Chief Designer Wu Weiren said, "Chang-third" launching major aspect of the task is clear of the brake, orbit, a soft landing and two players separation, which is a soft landing, "Moon" is the most important test. In addition, China was the next step from the Moon of the Lunar sample return, will by 2020 to achieve unmanned sample return to the moon.
Wu Weiren said that after the rocket launch, probe began travelling to the Moon, about 5 days later. After arriving at the moon first braking in recent months, commonly known as the brakes in recent months. Second, "the moon lady, first", "Chang-second" the difference is, the one-time 100kmx100km lunar probe designed as a circular orbit, used to be into elliptical orbit and then into a circular orbit. Run a few days later, detectors at a distance of 15 kilometers from the Moon's surface and began to decline. After landing safely, on the Rover from the lander separated, release, unlock, transferred to the tank, ladder, landing on the lunar surface.
"Rabbit" view of sky surveys and survey months
The Chang-third carry three scientific task: landing zone with the topography and geological structure of the inspection investigated landing zones and mineral composition of inspection and analysis of the chemical component integrated in place; and monthly tables of earth-moon space environment probe, with the moon as a platform for Earth observation, and space.
"The ' Chang ' e third ' detectors composed of Landers and Rovers, each equipped with 4 types of payloads. Is a terrain camera on the lander, landing, moon base and extreme ultraviolet optical telescope camera. ' Moon ' on the panoramic camera, Lunar laser radar, infrared imaging spectrometer and particle induced x-ray spectrometers, split them after landing. "The Deputy Director of the lunar exploration program, Vice Director of the Chinese Academy of Sciences yinhejun said.
Yin and June says, these loads are mostly Chinese scientists first developed for lunar exploration. They will complete the survey, view or check the month and other tasks. Month-based optical telescope is a telescope on the Moon, humans, extreme ultraviolet cameras for the first time observed from the moon to the Earth's plasma layer.
Dialog
"Moon Moon" the moon does not leak
Reporter: how far are we from Moon's abundant resources?
Wu Weiren (Chief Designer of the lunar exploration program): helium 3 is relatively abundant on the Moon, there are many metals, and chemical elements not found on Earth. But for helium-3, and Tower "first", "Chang-second" 's observation that the moon has 1 million tons to 5 million tons. Some scientists figure it used in nuclear fusion, 1992 worldwide electricity consumption is based, it is thought that as long as 8 tons of helium-3 on Earth's energy problems can be solved. But to achieve detection, acquisition, transport, return of the helium-3 is a great deal of scientific problems, is not achievable in the short term, but did not rule out such a possibility in the long run.
Reporter: "Chang-third" after the task is completed, Rover and Lander will stay on the Moon, with some secrets will be stolen?
Wu Weiren: high-tech, secret things things on largely technical, technical stuff on the Moon is also okay, and no one can reach the top to detect it or steal it, we don't have such worries. And this situation is unlikely to have, after a long, perhaps a State launches probe, it is at the same location or near, far surely can't go, so you don't have to worry about a leak problem. But technology is always in development, several years later, technology did not know how much of this development.
Reporter: did this mission is to plant the flag onto the Moon's surface?
Wu Weiren: both the Rover and Lander had a red flag, but not necessarily be inserted above the moon. After the probe landed, walking down the Rover, Rover and Lander, respectively the camera would shoot each other. Last hope finished photographing the flag back.
Reporter: "Chang-third" after the task is complete, plans and what is envisaged in the area of deep space exploration.
Wu Weiren: the next step should be sample return from the moon. Lunar sample return-related work in progress, and are proceeding smoothly, will achieve unmanned sample return to the Moon by 2020, is currently scheduled to be sampling Lunar soil 2 kg, and finally back to Earth.

新京报讯 12月2日1时30分，搭载着嫦娥三号的长三乙运载火箭在西昌卫星发射中心发射升空。1时52分，器箭分离。至截稿时，嫦娥三号已进入近地点高度200公里、远地点高度约38万公里的地月转移轨道。
约5天后到达月球
据中国探月工程总设计师吴伟仁介绍说，“嫦娥三号”发射任务的主要环节是近月制动、变轨、软着陆和两器分离，其中软着陆即“落月”是最重要的考验。另外，中国探月工程的下一步计划是从月球采样返回，将在2020年以前实现月球无人采样返回。
吴伟仁说，火箭发射以后，探测器开始奔向月球，大约历时5天后到达。到达月球后首先近月制动，俗称近月刹车。第二，与“嫦娥一号”、“嫦娥二号”不同的是，这次一次性地把环月探测设计成一个100km×100km的圆轨道，过去是先变成椭圆轨道，再变成圆轨道。运行几天后，探测器从距离月球表面15公里处开始往下降。安全降落后，月球车要从着陆器上分离、释放、解锁、转移到架舱上来，再从梯子上降落到月面。
“月兔”将巡天观地测月
此次嫦娥三号肩负三项科学任务：对着陆区与巡视区的地形地貌与地质结构进行调查；对着陆区与巡视区的矿物组成和化学成分进行综合就位分析；对地月空间和月表环境进行探测，并以月球为平台观测地球和太空。
“‘嫦娥三号’探测器由着陆器和月球车组成，它们各配置了4种有效载荷。着陆器上的是地形地貌相机、降落相机、月基光学望远镜和极紫外相机。‘玉兔’号上有全景相机、测月雷达、红外成像光谱仪和粒子激发X射线谱仪，软着陆后它们进行分时工作。”探月工程副总指挥、中国科学院副院长阴和俊说。
阴和俊表示，这些载荷大多是中国科学家首次研制用于月球探测。它们将完成巡天、观地、测月等任务。月基光学望远镜是人类首次把望远镜架上月球，极紫外相机将首次从月球对地球等离子体层进行观测。
■ 对话
“嫦娥玉兔”留在月球不会泄密
记者：我们距离利用月球丰富的资源还有多远？
吴伟仁（探月工程总设计师）：月球上氦3比较丰富，还有很多金属和化学元素是地球上没有的。但对于氦3来说，“嫦娥一号”、“嫦娥二号”的探测结果认为月球上有100万吨到500万吨。也有科学家算过它用于核聚变，以1992年全世界用电量为基础，人们认为，只要有8吨氦3就可以解决全地球的能源问题。但是要实现氦3的探测、采集、运输、返回是一个很大的科学难题，不是短期内能够实现的，但从长远看不排除这种可能性。
记者：“嫦娥三号”任务完成后，月球车和着陆器会留在月球上，上面一些机密会不会被窃取？
吴伟仁：至于高技术、机密的东西主要是技术上的东西，技术上的东西留在月球上也没关系，也没人能够到上面去探测它或窃取它，我们没这种担心。而且短期内这种情况也不会有，以后时间长了，说不定某个国家发射探测器上去了，那要在同样地点或者在附近，远了肯定去不了，所以不必担心泄密的问题。而且技术总是在发展的，若干年过后，技术不知道又发展到什么程度了。
记者：这次任务会把五星红旗插到月球表面吗？
吴伟仁：月球车和着陆器上都有五星红旗，但不一定是插在月球上面了。探测器降落下去以后，月球车走下来，月球车和着陆器分别都有相机，会互相拍。最后是希望能够把五星红旗拍照后传回来。
记者：“嫦娥三号”任务完成以后，在深空探测领域的计划和设想是什么。
吴伟仁：下一步应该是从月球采样返回。月球采样返回相关工作正在进行中，而且进展比较顺利，会在2020年前实现月球无人采样返回，目前定的是要采样2公斤月壤，最后带回地球。
