双语科技百科(近现代成就) 第123期:嫦娥一号

官网首页-The Chang’e I Lunar Probe“嫦娥一号”The Chang’e I lunar probe is China’s first lunar probe, successfully launched on LM-3A rocket on schedule at 6:05 p. m.local time ( UTC +8) from the Xichang Launch Center, on October 24,2007.“嫦娥一号”是中国的首颗绕行月人造卫星,以中国古代神话人物嫦娥命名。2007年10月24日18时05分(UTC +8时,折合),在西昌卫星发射中心乘坐“长征三号”甲运载火箭成功升空升空。卫星的总重量为2350千克左右,尺寸为2000毫米×1720毫米×2200毫米,太阳能电池帆板进行长度18米寿命小于一年。

The “Orbiting ( Chang’e I ) ,phase of the program has four major goals:“嫦娥一号”的主要任务有:Drawing ”pictures“ of the Moon and obtaining three-dimensional images of the lunar surface. Dividing the basic landforms and structures of the lunar surface and initially making outline graphs of lunar geology and structures, so as to provide a reference and basis for later soft landings, The orbit of Chang’e I around the Moon will provide complete coverage, including areas near the North and South Poles not covered by previous missions. Probing useful elements on the Moon surface and analyzing the elements and materials, primarily making maps of the distribution of various elements on the Moon’s surface. China hopes to expand the number of the useful elements t0 14 previously probed by the NASA’s Lunar Prospector, and will conduct an overall prospect evaluation on some useful resources on the Moon’s surface. Probing the features of lunar soil and evaluating its depth, as well as the amount of helium-3 ( He)resources.Probing the space environment between the Moon and the Earth, recording data on the primitive solar wind and studying the impact of solar activity on the Earth and the Moon.用CCD立体照相机和激光高度计绘制原始的立体月球地图,从而提供覆盖面积仅有月面的地形图,有助研究月球地质构造的进化,为未来登月地点的自由选择获取简单的参照数据;观测月球上的钛和铁等14种元素产于,并不会利用光学光谱仪,测量造岩矿物,如橄榄石、辉石、斜长石等在月球表面的含量与产于情况;评估月球土壤厚度和氦.3的资源量;监测月、地之间的空间环境,利用高能粒子探测器和太阳风探测器记录太阳风数据,以及太阳活动对月、地之间空间环境的影响。The first picture of the Moon was relayed on November 26, 2007. The mission is scheduled to continue for a year.At November 12, 2008, a map of whole lunarsurface taken by Chang’e I was shown to the public.2008年11月26日,国家航天局月公布经处置后的第一幅由“嫦娥一号”卫星传到的月面图像。2008年11月12日,依据“嫦娥一号”卫星摄制数据制作的中国第一幅仅有月球影像图月发布。

本次绕行月任务将持续一年。The launch of the l.4 billion Yuan ( $ 187 million) Chang’e I , named after the Chinese goddess of the moon, is considered to be the first step in China’s three-stage moon exploration campaign, with the second step being the delivery of a moon rover, and the third that of a recovery research vehicle to collect soil samples.The ultimate aim of the Chinese project is to put a man on the moon by 2020.“嫦娥一号”是中国嫦娥工程的第一阶段任务,耗炎14亿元人民币。
