为何印度至今尚未登月,美国和俄罗斯等国近50年前就成功了

Kshitij Salgunan, Indian Internet activist

It is basically USELESS to send a person to moon. By useless, I hearby mean that we don't get any new knowledge or new sample or anything useful. The same is the case of sending a person to mars.

We can instead send robots which can collect samples, test them and they can work endlessly there.

Sending a human will also require development in various other technologies like 'life supporting space vehicle' which can be extremely costly.

The cost of sending a single human to moon under current circumstances will be 100times the cost of sending the mars probe (manglayaan). The Govt. of India allocates only a tiny budget for space research, so tiny that it is unbelievable that they were able to make, plan and send a probe to mars!

Read this descriptive answer to know more abut Mangalyaan mission:- What is the breakdown of cost for a space mission like India's Mars mission?

把人送上月球,基本上没什么实际用处。所谓无用,我指的是我们并不能从中任何新知识或新样本或任何有用的东西。把人送到火星上也一样。

我们可以把机器人送去收集样本,测试样本,它们可以在那里不眠不休地工作。

而载人航空需要研发其他技术,比如“可维持生命的航天器”,造价可能会非常昂贵。

在目前情况下,将人送上月球的成本将是将发射火星探测器的100倍。印度政府对太空研究的预算拨款极少,少到他们能够制造、筹划以及向火星发射探测器都变成了一场天方夜谭!

大家可以读一读这个回答,了解更多关于曼加里安发射任务的细节:太空发射任务,以印度的火星任务为例,各项成本是多少?

In the 1960s, the US put all its heart into NASA and the moon mission. There was a big fear that US would lose out to Soviet Union (Russia) in the space race. Such an urgency is the best incentive for scientific development. Resources were poured in and it was the national priority. US spent around $35b in today's dollars year after year.

To put that in context, India spent $1.1 billion on ISRO last year in a year it sent the MARS mission. It has a fraction of the resources that NASA got. However, even NASA has to rely on the Russians to get to the space these days, as the older priorities have gone and the gap between NASA and ISRO is slowly reducing.

20世纪60年代,美国把所有精力都投入在NASA和登月任务上。人们非常担心美国在太空竞赛中会输给苏联(俄罗斯)。这种紧迫性是科学发展的最佳动力。资源大量注入,这是国家的当务之急。以今天的美元价值计算,美国那些年花费了大约350亿美元。

去年,印度在发射火星任务的一年中,为ISRO花费了11亿美元。它的资源只占到了NASA的一小部分。然而,即使是NASA现在也不得不依靠俄罗斯人进入太空,因为历史上的当务之急不复存在,NASA和ISRO之间的差距正在慢慢缩小。

Besides that the US had historically imposed plenty of restrictions on ISRO and we had to bootstrap a lot of it without outside help. U.S. SANCTIONS IMPOSED ON RUSSIAN, INDIAN SPACE GROUPS (1992 news). NASA, in comparison, had the best of talent from all over the world.

此外,美国历史上曾对ISRO施加过大量限制,我们不得不在没有外援的情况下自力更生。美国对俄罗斯、印度航天集团实施制裁(1992年的新闻)。相比之下,NASA拥有来自世界各地最优秀的人才。

I must study politics and war, that our sons may have liberty to study mathematics and philosophy. Our sons ought to study mathematics and philosophy, geography, natural history and naval architecture, navigation, commerce and agriculture in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry and porcelain.

-- John Adams (Second American President)

Gandhi, Patel, Netaji, Nehru, Rajaji, Shastri and Prasad studied politics and war, so that we have the liberty to pursue mathematics, commerce and engineering. We have started to see the positive effects. If we keep walking that path and do our duty well, our children could study poetry and music.

我必须学习政治和战争,这样我们的后代就可以自由地学习数学和哲学。我们的后代应该学习数学和哲学、地理、自然史、造船、航海、商业和农业,以便给他们的孩子学习绘画、诗歌、音乐、建筑、雕塑、挂毯和瓷器的权利。

——约翰·亚当斯(美国第二任总统)

甘地、帕特尔、尼塔吉、尼赫鲁、拉贾吉、沙斯特里和普拉萨德学习政治和战争,这样我们就有学习数学、商业和工程学的自由。我们已经开始看到了积极的影响。如果我们继续沿着这条路前进,好好履行我们的职责,我们的孩子就能学习诗歌和音乐了。

Is going to the moon the only way to infer about some country's technological progress ??

  • India came up with their own Cryogenic Engine when it was refused help.
  • The Agni missile family are devastating and accurate
  • We have nuclear research
  • Majority of the programmers and research people overseas are Indian in origin.
  • The Mangal Yaan was built within a budget less than that of the movie GRAVITY !
  • Indian Engineers are highly demanded in the Industry

登陆月球时判断某个国家技术进步的唯一方法吗??

  • 当求助无门时,印度独力研发了低温发动机。
  • 火神导弹系列拥有极高的毁灭性和精确性
  • 我们有核武器研究
  • 大多数海外程序员和研究人员都是印度人。
  • 曼加尔的建造预算比电影《地心引力》的预算还要低!
  • 印度工程师在行业中非常紧俏。

I don't think its justifiable to conclude someone's technological progress depending upon moon missions.

There are better ways to spend the same amout of money

Moon missions were taken to explore the moon and not to show technological advancement. Since we already know what is up there. We don't find it reasonable to go up there :P Better let the money stay in Swiss Banks

我认为用登月任务来评判某个国家的技术是否发达是不合理的。

我们可以把同样的钱用在更好的地方。

登月是为了探索月球,而非炫耀技术的进步。既然我们已经知道月球上面是什么样了。我们觉得登月不合理,最好把钱留在瑞士银行。

first question should come in mind why usa is able to send man into moon in 1950 and 1960 but after that it fail to send  what is responsibe for ussr and usa becoming so powerful  in 1950 and 1960 in space scientific reserach and but after that it becom weak  reasons for usa and ussr capability to send man into moon in 1950 and 1960 are :-

1 german expertise in rocket : germans are expert in rocket engineering in 1940 germans created powerful rockets in 1940. their roce ket expertise is best in world due to large reserach experience.after germans got defeated ,usa and ussr  take german rocket scientists to their countries to develop powerful weapons .russia and usa was able to develop weapons quickly due to expertise of german scientist . than question come into mind " why usa is able to send man into moon " reason is von braun who is architect of saturn v rocket and most genius german . usa got most capable rocket scientist in world.

2 strong economy of usa and russia : usa and russia economy is very strong at that time that why they were able to afford expensive reserach

第一个问题应该是,为什么美国能够在20世纪五六十年代把人送上月球,但后来又不行了?苏联和美国的太空科学研究在20世纪五六十年代那么强大,之后为何如此积弱?美国和苏联能在20世纪五六十年代将人送上月球的原因是什么?

1.火箭上的德国专家:德国人精通火箭工程,1940年德国人发明了威力强大的火箭。他们在火箭方面的专业知识是世界上最好的,因为他们有丰富的研究经验。德国战败后,美国和苏联把德国的火箭科学家带到各自的国家研制强大的武器,俄罗斯和美国凭借德国科学家的专业技术迅速研制出了武器。当我想到“为什么美国能把人送上月球”这个问题时,我想到了冯布劳恩,他是土星五号火箭的设计者,也是德国最富天才的人。美国获得了世界上实力最强的火箭科学家。

2.美国和俄罗斯的强劲经济:美国和俄罗斯的经济在那个时候非常强大,因此他们能够负担得起昂贵的科研费用
