网友：在尼尔·阿姆斯特朗登月的视频片段中，你可能会看到美国国旗似乎在飘动。这在月球上是怎么发生的呢？你是否真的观看过这些视频，还是仅仅重复了你在某个阴谋论网站上看到的内容？实际上，如果你仔细观察视频，就会发现国旗之所以会动，是因为宇航员在插旗时的振动和摇晃造成的。

In some videos of Neil Armstrong landing on Moon, I have seen flag of U.S.A waving. How's that possible on moon?
Have you actually watched those videos, or are you just regurgitating something you read on a conspiracy web site? Because it's pretty obvious if you actually watch the video that the reason it's waving is because the astronaut is shaking the darn thing.

The flag was supported by a stiff wire and shuving into the ground the pole also put some vibration in the wire which obviously caused the flag to wave. This question has come up many times by folks who are convinced about conspiracy by NASA. In fact, its very hard for the goverment to hide things for long due to profit or political motive to expose. Like, The H bomb, or Nixon's tapes and of course the young lady hidding under Clinton's desk.
美国国旗之所以看起来在飘动，是因为它下面有一根硬钢丝支撑，而且当旗杆被插入月球表面时，钢丝产生了一些振动，这自然会让国旗呈现出飘动的样子。这个疑问经常被那些相信NASA有阴谋论的人提出。事实上，由于利益或政治动机，政府想要长期隐瞒事情是非常困难的。想想看，无论是氢弹的秘密，尼克松的录音带，还是与克林顿办公桌下的那位年轻女士有关的传言，最终都被曝光了。
I've been hearing this one since 1970 when I was 25 and it will linger long after I'm gone. Gullibility knows no limits.
自从1970年我25岁时，我就不断听到这种阴谋论，而且即使我离世后，这样的说法可能还会继续流传。这表明，人们容易受骗的程度是无限的。
A moon landing video footage I saw showed the American flag waving.
How is that possible considering that the moon lacks atmosphere and therefore any kind of wind-flow is impossible?
Torque, you dorque! The astronauts had to jimmy it into place. Also, the moon does experience the occasional moonquake, some of which could have been artificial in nature, caused by the Apollo Lunar Surface Experiments Package (ALSEP) seismographic experiment, in which a mortar system launched explosive packets some distance away and seismographs measured the resulting shock wave to determine the composition of the moon.
我在观看的月球着陆视频中，美国国旗似乎在飘扬。然而，由于月球上没有大气，是不可能存在风的，这究竟是怎么回事呢？其实，这是因为宇航员在将国旗插入月球表面时，需要用力使其保持展开状态。此外，月球确实会偶尔发生月震，其中一些可能是人为因素造成的。这主要是由阿波罗月球表面实验包（ALSEP）的地震学实验引起的。在这项实验中，一个迫击炮系统会向远处发射爆炸包，地震仪会测量由此产生的冲击波，从而分析月球的内部结构。
If there is no atmosphere on the moon, then how is the American flag flying when they planted it during the moon landing in 1969?
When the flag was planted, the flag was moving because of conservation of momentum and the stiffness of the cloth. That started it flapping. Without air, there was no air resistance to slow it down - so it flapped much faster and much longer than you’d expect it to from such a gentle initial force.
月球上没有大气，1969年登月时插上的美国国旗看起来怎么会飘动呢？
插旗时，国旗之所以会动，是因为布料的硬度和动量守恒定律导致的。这种动作让国旗开始摆动。月球上没有空气，因此也就没有空气阻力来减慢它的摆动速度，所以国旗摆动得比我们预期的要快，持续时间也更长，尽管最初的力量非常轻微。
So the ONLY thing that could slow the flapping down was the internal friction between the strands of cloth inside the flag and the energy dissipated by bending those fibres.
That meant that the flag flapped for quite a while before eventually coming to a stop.
由于月球的重力较小，对布料的拉力也较小，而且旗杆设计有一个水平的支撑部件来托起国旗（因为月球上没有风）。
因此，唯一能减缓国旗摆动的就是布料内部纤维之间的摩擦力，以及纤维弯曲时消耗的能量。
这意味着国旗需要一段时间才会停止摆动。
Some interesting facts about those flags:
With the amount of solar radiation and intense UV light - the flags have long ago been bleached completely white.
这导致许多缺乏批判性思维能力和对物理学知之甚少的人，错误地将这种摆动视为登月造假的“证据”。然而，这种不寻常的摆动实际上恰恰证明了登月是真实的！
国旗的安置其实是在最后关头才决定的。NASA一度无法确定，插上美国国旗是否会被解读为一种挑衅行为，好像在宣称月球是美国的领土。因此，当最终决定要插旗时，他们匆忙派遣了一名初级职员去附近的商店购买国旗。这些国旗并不是为这次任务特别制作的……而且旗杆的设计——特别是它带有的可折叠水平支撑部分——是在准备登月过程中最后确定的设计细节。
A moon landing video footage I saw showed the American flag waving. How is that possible considering that the moon lacks atmosphere and therefore any kind of wind-flow is impossible?
This question has been asked and answered ad nauseam.
There was no wind moving the flag.
The flag was moving because of the momentum imparted to it as the astronauts themselves were moving it about as they were planting it.
The flag stopped moving almost immediately after the Astronauts stopped messing with it.
我在观看的月球着陆视频中，美国国旗似乎在飘动。考虑到月球没有大气层，因此任何形式的风都不可能存在，这怎么可能呢?
这个问题已经被多次提出并解答。
实际上，并没有风在吹动国旗。
国旗之所以会动，是因为宇航员在插旗时给它施加了动力。在宇航员停止摆弄国旗后，旗子几乎立刻停止了移动。
In point of fact, it actually continued to move for a slight bit longer after the astronauts stopped messing with it, than had there been an atmosphere. As there was no air to act as a dampening force to the flag’s movement. No air resistance.
Had there been an atmosphere, but still— calm air… the flag would have stopped moving even sooner.
由于没有空气或微风使它移动，它停止后没有更多的运动。
事实上，由于月球上缺乏空气来对国旗的摆动产生阻力，国旗在宇航员停止操作之后，相较于地球上有大气的环境，还多持续了一会儿的摆动。
如果有大气存在，哪怕是在风平浪静的情况下，国旗的摆动会更快地停止。
The flag behaved EXACTLY AS IT SHOULD in the vacuum of space.
Try again Flat Earth Idiots.
如果有空气和微风，国旗会持续飘扬。
在太空的真空环境中，国旗的表现完全符合物理规律。
对于那些坚持错误观念的人，请再次审视事实。

This was explained on TV in the live broadcast at that time of the first landing, before the flag was brought out. The flag not only had a rod at the top to spread it out, but either the rod was springy, or there was an added spring, I forget which, to help create the waving effect. This was quite deliberate. It was just a little bit of whimsy and patriotic pride , and fun, from the engineers. I think it was to go along with the part in the national anthem that says “Oh say does that star spangled banner yet wave, o’er the land of the free and the home of the brave.”
我看到的一段登月录像显示，美国国旗在飘扬。考虑到月球没有大气层，因此任何形式的风都不可能存在，这怎么可能呢?
在首次登月任务的现场直播中，宇航员展示国旗之前，解说已经向观众解释了国旗的设计。国旗顶部装有一根横杆来撑开它，而且这根杆子具有弹性，或者是另外加装了一个弹簧（具体细节我记不清了），这样做的目的是为了模拟出一种飘扬的效果。这种设计是经过深思熟虑的，它体现了工程师们的一点幽默感、爱国心以及创意乐趣。我认为这样的设计是为了呼应美国国歌中的那句歌词：“哦，你看星条牌不是还高高飘扬,在这自由的国土,勇士的家乡”
正是这些事实让我确信登月是真实的。当你关注整个过程，阅读新闻报道，观看电视转播时，你会发现那并不是虚构的剧本，而是真实的、有些混乱的生活写照。尽管那时候我们的科幻小说里已经有了许多更先进的设想，但能在现实生活中实现这样的壮举，无疑是一次美妙的体验，它让全世界都为之振奋，共同见证了这一刻。

I always find this particular question amusing. I’ve heard so many people use it as a “Gotcha! Explain that, Mr. Apollo Was Real!” What’s so amusing is that the moving flag is one of the better pieces of evidence that the video footage from the Moon’s surface is real.
Surely the conspiracy brigade can do better than this tired and endlessly explained “non-obxtion.”
我看到的一段登月视频显示美国国旗在飘动。考虑到月球上没有大气层，因此不可能有任何风流动，这怎么可能呢？
我总觉得这个问题很有趣。我听过很多人把它当作一种“明白了吧！解释一下吧，阿波罗登月是真的！”的质问。好笑的是，国旗的飘动反而是证明视频确实来自月球表面的一项更有力的证据。
阴谋论者们应该能够提出一些比这种已经被反复澄清和驳斥的“无稽之谈”更加有力的论据。
Why is the American flag shown waving on the moon when there is no wind and did NASA ever answer this question?
It's not waving. It's held up by a crossbar across the top of the flag, and wrinkles in the material make it look like it's waving.
The only time it actually flapped was when it was buffeted by the backwash of the lunar lander's rocket engine as it took off. This actually knocked the flag over, as we saw via the automatic TV camera left behind.
为什么美国国旗在没有风的时候在月球上飘扬，美国宇航局回答过这个问题吗?
美国国旗并没有真的飘动，而是通过旗顶部的一根横杆固定。布料上的皱褶给人一种飘动的视觉效果。
实际上，国旗真正出现摆动的情况仅有一次，那就是在登月舱起飞时，由于火箭引擎的尾流冲击所导致。这股力道实际上把国旗给吹倒了，这一过程被我们留在月球上的自动电视摄像机捕捉到了。
OMG, the US flags were deployed on a spring loaded bar that snapped into place and the release of spring energy created the flapping. There's no atmosphere on the moon, duh, so it's obvious the flapping was caused by the deployment mechanism. It ain't rocket science.
"哇，美国国旗是通过一个弹簧装置展开的，当弹簧弹开时释放的能量让国旗产生了摆动。月球上没有大气，这是常识，所以很明显，这种摆动是由旗帜的展开机制造成的，这并不复杂。
How does the the flag move on the moon if there is no wind?
It doesn't. The movement you see in the videos of the landing is due to the chain weighting down the bottom swaying from the movement of placing the flag. With no atmosphere it would wave for a while, but eventually whatever the fabric equivalent of rolling friction is, will slow it down.
如果月球上没有风，国旗怎么会动呢？
它不会动。你在登陆视频中看到的移动是因为固定在底部的链条在放置国旗时的摆动。由于没有大气层，它会摆动一会儿，但最终，不管是什么类似于滚动摩擦的织物因素，都会让它慢下来。

That flag looks as if it has a straight rod inserted across the top of it to hold it out straight. The bottom looks as if it is floating (like astronauts hair in the ISS) not being blown about by a breeze.
那面国旗看起来好像在顶部插入了一根直杆，使它保持展开状态。底部看起来像是在漂浮（就像国际空间站中宇航员的头发一样），并没有被微风吹动。
Is there wind on the moon? If not, how come in the footage of Neil Armstrong on the moon, the US flag is waving?
There isn’t any wind on the moon. Well, technically the Moon has an extremely thin “atmosphere,” but by Earth standards, it’s a hard vacuum. The film of the flag “waving,” as you put it, has nothing to do with there being any wind. The flag was secured by two sides to a metal frx. When dude planted it, it started vibrating and the flag being attached to it, the flag also moved. Because there was no air to create any drag on the flag and slow down the waving motion, it just sorta kept on waving.
月亮上有风吗？如果没有，那么在尼尔·阿姆斯特朗在月球上的录像中，美国国旗怎么会飘动呢？
月球上没有风。严格意义来说，月球的“大气层”非常稀薄，但按照地球的标准，它是一个高真空。你所提到的国旗“飘动”现象，其实和风没有任何关系。国旗是固定在一个金属框架上的。当宇航员将其植入月球表面时，框架产生了振动，连带国旗也动了。由于月球上没有空气，也就不存在空气阻力来减缓国旗的摆动，因此国旗持续地保持着摆动的状态。

Actually, you have drunk the koolaid because you think there is no air on the moon. Of course there is air. It is a secret that NASA and the Illuminati have tried to hide so they can keep their cities and bases there a secret. After all, if the general public knew there was air on the moon, everyone would want to go there, and then the 33rd Degree Masons would have to find another place to hide.
我看到的一段登月录像显示，美国国旗在飘扬。月球没有大气层，按理说不可能有风，但这是怎么回事呢？
事实上，你可能已经被误导了，因为你认为月球上没有空气。但事实上，月球上确实存在空气，只是NASA和光明会一直在保密，目的是为了隐藏他们在月球上的秘密城市和基地。如果大众知道月球上真的有空气，那么每个人都会渴望去那里探险，这样一来，33级共济会成员就不得不重新找个隐蔽的地方了。
But, try as they might, that pesky lunar atmosphere made the flag move, so we know that it is all a hoax to fool us.
阿波罗登月任务的所谓目的，实际上是为了前往月球表面一个精心搭建的场景，那里被设计成看似没有空气，以便他们可以假装必须穿戴那些庞大而笨重的宇航服来呼吸。为了增加可信度，他们特意选择了一个没有任何植被的月球荒漠地带。
尽管他们费尽心机，但月球上那微弱的大气作用却使得国旗产生了摆动，这个现象让我们意识到所谓的登月不过是一个用来迷惑我们的大骗局。
There is of course no atmosphere on the Moon so the flag isn’t “flapping”. What the flag is doing is waving. Waves still propagate in materials whether they are in an atmosphere or not. This is demonstrated numerous times and is why the flag required a rod at its top to make it stand out.
月球上自然没有大气层，所以国旗并没有像在风中那样“摆动”。实际上，国旗是在‘摆动’。波动现象即使在没有大气的环境中也能在物质中传播。这一点已经通过多次演示得到证实，也正是国旗顶部需要一根横杆来支撑，使其更加显眼的原因。
现在你提到的所谓登月造假的‘证据’已经被澄清，也许你应该去探究那些关于所谓骗局的其他荒诞不经的说法（提前告诉你：它们都是无稽之谈），然后回归理性，认识到登月确实是真实的，是人类历史上最伟大的成就之一……除非你已经被那些心怀恶意的网络喷子彻底洗脑了。

The US flag on the Moon during the first Moon landing appeared to be flapping because of the way it was designed. The flag had a horizontal rod along the top edge that allowed it to extend outwards, and it was also made of a lightweight material that could easily move in the absence of wind or atmosphere. When the astronauts were planting the flag, they rotated it back and forth to get it into the ground, which caused the flag to move and appear as though it was waving.
首次登月时，月球上的美国国旗之所以看起来像在飘动，是因为它独特的设计。国旗顶部装有一根横杆，让它能够展开，同时国旗采用轻盈材质，在无风无大气的环境中也能轻易摆动。宇航员在将国旗植入月球表面时，为了稳固它，会来回旋转国旗，这样的动作让国旗产生了摆动，给人一种它在风中飘扬的视觉效果。
