美国《天空与望远镜》杂志网站批评中国嫦娥撞月

认为没有充分利用一个很好的机会做更多的有意义的实验。
我个人认为这些批评是很有道理的(尽管口气不太尊重)。
结合嫦娥远低于印度探月的绩效(1/10分辨率等),应该深刻反思。

学术探讨,很正常。最好把原文转过来。

是的,有原文看看::42::让人了解一下人家的意见才好!

Chinese Craft Whacks the Moon

The Chinese people are often stereotyped as being inscrutable, meaning "difficult to fathom or understand." And that about sums up my reaction to yesterday's news that the flight controllers at the Chinese National Space Administration intentionally sent the Chang'e 1 orbiter crashing into the Moon.

The design of China's Chang'e 1 spacecraft, which orbited the Moon from November 5, 2007, until March 1, 2009 , was based on an existing communications satellite.
China National Space Admin.According to this report from the Xinhua news agency, ground zero was 1.50° south, 52.36° east. That's a nondescript tract of Mare Fecunditatis about 90 miles (145 km) from the crater Messier.

The spacecraft, which carried eight experiments, rocketed toward the Moon on October 24, 2007, and had been in lunar orbit for 16 months. And it was beefy, weighing in at more than 2 tons. That's comparable to the mass of a Centaur rocket that NASA's hopes to drill into one of the lunar poles later this year, along with the LCROSS spacecraft. Chang'e 1's impact undoubtedly made a sizable splash that should have been observable from Earth.

So here's what I don't understand:

(1) The end came at 8:13 Universal Time, which is 4:13 p.m. in Beijing's time zone. That means the Moon was up, but sunset was still about two hours away — not ideal conditions for lunar observing.

(2) The near-side impact site was in daylight, yet the crash would have been closer to the terminator, or even in shadow, just a couple days ago. So why pick March 1st and not February 27th?

(3) NASA officials are lining up an army of telescopes to try to record the LCROSS finale, now scheduled for early September or thereabouts. Wouldn't it have made sense for Chinese scientists to alert their Western colleagues of Chang'e 1's impending crash? At the very least, it would have been a useful test exercise.

Maybe I'll get answers to some of these questions in three weeks, when I head to Houston for the annual Lunar and Planetary Science Conference. A contingent from the Chang'e 1 project will be there to present results from the mission.

没错,就是这个。
个人认为这次探月的真正科技内涵的确欠缺。尤其是被印度的成果明显比下去了。

我个人觉得这篇文章的作者不够权威,可能是仅仅是一家之见
人家印度有美国帮着呢!我们国家搞太空探测,那是处处碰壁,人家外国什么技术都不给,与印度比起来差一些是理所应当的。我觉得大家还是应该客观地分析一下比较好。
我参加过欧阳自远先生的报告会,他在报告中也诉过苦衷,说我们搞航天遇到的每个问题,向外国那边请教,人家立即就答应会告知我们的,但最终结果是,几个月过去了,一点音信也没有,最后白白耽误咱的航天计划。也就是说,航天探测技术是咱一步一个脚印的走过来的。不像印度,美国人一帮,大踏步前进。

我觉得中国的航天事业采取的是稳步前进。到目前为止取得的成绩已经不错了!当然这要看和谁比。美国是哪年等月的?

切!
什么都和阿三比,有意思吗?!::070821_16.jpg::
要比就和美国比!!!!!!!::070821_13.jpg::

不知LZ认为这次探月真正的科技内涵是什么??
印度探月具体都有哪些成果??

中国毕竟是发展中国家,离世界先进水平是有相当距离的,不要搞思想大跃进,要面对现实

赞同后心发冷的观点,我们应该了解并且把当前某领域的领先科技作为我们的目标,但同时也要有我们的自己的思想和计划,没必要和别人盲目攀比。

况且,并不是所有的信息都是我们所能了解的。

BL-LAC 发表于 2009-3-10 11:50 AM http://www.astronomy.com.cn/bbs/images/common/back.gif这话我越看越冷,阿三连国民经济都上不去就搞这种政纪工程,随便扔个秤砣就算登月,最不能忍的就是一变轨就差了千里,好几次变轨失误,最后转移轨道改来改去浪费了大量燃料,不知谁该反思……
