Chief Engineer, Moon said China already has tentative | moon Mars Mars | | engineers _ news

Reporter (reporter Porto Recanati) Wu Weiren, Chief Designer of China's lunar exploration engineering yesterday revealed that China has the ability to explore Mars, but wanted to go, depending on State financial support and national policy-making.

Yesterday, Wu Weiren, a number of guests in the lunar exploration project technical leader Association "scientists face-to-face with the media". Wu Weiren said in answering the question when China will study Mars, in fact as far back as when Chang-successful launch of Yi、erhao, we have the ability to study Mars. Specific launch time window depending on the size-is being developed in China long March rocket launch vehicle, fifth, the existing long March rocket, third largest lift 600 tonnes to become immortal, the series of maximum thrust of 1100 tons of rockets, so do the Mars Rover is easy. "Our national satellites, Lunar, Mars exploration lines, attention taken together, every step of the way to lay a good foundation for the next step. "Wu Weiren said.

For cost high of agent months works what whether has actual meaning, Wu Weiren first lifted has a group digital description China agent months works of cost: United States Apollo Moon works official said put 25 billion dollars, actual is more than this digital, total continued more than 10 years, average annual put of money accounted for United States when GDP of 2% to 2.5%, and China agent months works currently of put about accounted for my when GDP of was of several, "so we put of money not many. ”

As regards the practical significance of the lunar exploration program, said Wu Weiren, according to United States after successful Apollo calculates that about each invested 1 last May 15. US-Soviet Moon exploration project after many technological achievements transfer to civilian and defense, efficiency is very high. Like the moon lander, third of four legs of the new, four-legged structure test systems and bar special materials, mesh-like structure of the Lunar Rover with four wheels, is a major breakthrough in materials science. "Apollo project led to more than 3,000 transfer to civil, our lunar exploration program will bring much fruit is not statistics, but it is certainly a large number. "Wu Weiren said.

探月总工程师称中国已具备探火星能力|探月|火星|工程师_新闻资讯

　　本报讯(记者雷嘉)中国探月工程总设计师吴伟仁昨天透露，中国已经具备探测火星的能力，但要不要去，取决于国家财力的支持和国家决策。

　　昨天，吴伟仁等多位探月工程技术负责人作客中科协的“科学家与媒体面对面”活动。吴伟仁在回答中国何时探火星的问题时表示，其实早在嫦娥一、二号发射成功时，我国就有探火星的能力了。具体发射时间窗口取决于火箭的大小——我国正在研制长征五号运载火箭，现有的长征三号火箭最大推力是600吨，嫦娥系列的火箭最大推力近1100吨，因此要做火星探测器很轻松。“我们国家对卫星、月球探测、火星探测都比较成体系，重视综合考虑，每一步都为下一步打好基础。”吴伟仁说。

　　对于成本高昂的探月工程究竟是否有实际意义，吴伟仁先举了一组数字说明中国探月工程的成本：美国阿波罗登月工程官方称投入250亿美元，实际是不止这个数字，共持续10多年，平均每年投入的钱占美国当年GDP的2%至2.5%，而中国探月工程目前的投入约占我国当年GDP的万分之几，“所以我们投入的钱不是很多。”

　　至于探月工程的实际意义，吴伟仁表示，据美国阿波罗登月成功后的测算，约每投入1元最后可以产出15元。美苏探月工程的很多技术成果转移到民用和国防后，效益是很高的。比如此次嫦娥三号着陆器四根腿所采用的新材料、四只脚的结构检测系统和横杆的特殊材料、月球车四个轮子的丝网式结构等，都是材料学的重大突破。“阿波罗工程带动了3000多项成果转移到民用，我们的探月工程会带来多少项成果目前还无法统计，但肯定是大量的。”吴伟仁说。
