Today, as we mark the 54th anniversary of humanity's audacious leap onto the surface of the moon through the Apollo mission, we are drawn back to the remarkable day of July 20, 1969. That's when Neil Armstrong, an embodiment of the daring American spirit, descended from the lunar module and etched the first human footprints onto the lunar dust. This epoch-making feat illuminated the breathtaking scale of human ingenuity, casting an undying light on the path of scientific progress.
However, in our times, filled with the cacophony of digital chatter and the murky shadows of misinformation, there are those who question the veracity of our lunar feat. They assert that NASA's triumphant moon landing, this giant leap for mankind, was a mere illusion, a grandiose deception undermining our shared history. As a devoted scientist with over two decades of service within the hallowed corridors of NASA, I once thought it unnecessary to counter these conspiracy theories. But today, high above the clouds, with a few hours in hand, I find it incumbent upon myself to shed some light on this subject. Armed with the sword of scientific rigor and shielded by firsthand experiences, debunking these conspiracy theories and defending the hallowed achievements of NASA, and the spirit of scientific exploration itself, is not just possible but essential.
The core of moon landing conspiracy theories revolves around alleged anomalies in photographic and video evidence, assumed political motivations of the Cold War era, and so forth. To shine the light of truth on these points, we need the lens of scientific and historical analysis.
1. "Anomalies" in Photography and Film
A rigorous examination of the Apollo images requires a profound understanding of lunar conditions and photographic principles. For instance, the so-called "anomalies" in shadows are actually results of lunar surface topography and the distortions caused by wide-angle lenses, which can be verified through experiments. Therefore, it's incorrect to imply multiple light sources from these "anomalies". Moreover, scientific experiments have shown that the lunar surface's light reflection, or "albedo", can explain the seemingly strange shadow phenomena.
Regarding the "fluttering" American flag questioned by conspiracy theorists, this is actually a design effect of the flag in a vacuum. The flag is supported by a horizontal bar and was subjected to inertia during installation by the astronauts. In the airless environment of the moon, this ripple effect would persist, while on Earth, air resistance would quickly stop such motion. The TV show "MythBusters" (https://en.wikipedia.org/wiki/MythBusters) successfully replicated this phenomenon in a vacuum.
Furthermore, the "missing stars" are due to the daylight conditions on the moon and camera settings. The brightness of the sunlight and the camera parameters set to capture well-illuminated astronauts and equipment made the faint stars difficult to capture. Considering the moon lacks atmospheric scattering, objects directly reflect sunlight. If the film's exposure time were long enough to display stars, it would result in overexposure, causing the images of the astronauts and lunar landing equipment to be overly bright and blurred.
2. Historical Background
To view the moon landing as a Cold War deception for victory in the Space Race overly simplifies and neglects key historical facts. By 1969, the U.S. had already demonstrated its space technology capabilities through a series of achievements, such as the first spacewalk. Furthermore, the moon landing program involved tens of thousands of scientists, engineers, and technical and media personnel. If a fraud of such magnitude existed, it's unlikely it could have been kept secret for over half a century. Moreover, during the Cold War, the Soviet Union, the U.S.'s main competitor, closely monitored NASA's Apollo missions and never questioned their legitimacy.
3. The Issue of Missing Master Tapes and Blueprints
Regarding the "missing master tapes" raised by conspiracy theorists, the fact is, slow-scan television was used during the Apollo landings. What was lost were the first reel-to-reel tapes derived from the master tapes, not the master tapes themselves. After a period of search, these materials have been found, restored, and made public.
Concerning the "loss of Saturn V blueprints" and "why Saturn V was not used subsequently", in reality, physical models of the Saturn V rocket are still publicly displayed today. After the Apollo program, Saturn V was used for Skylab missions. For missions in Earth orbit, we don't need large rockets like Saturn V, just as we don't need to fly a plane to buy groceries at the local store. Moreover, from a modern technology perspective, Saturn V's design is somewhat outdated. Current rockets, like Delta IV Heavy and Falcon 9, are safer, more reliable, and provide more options to meet various space mission requirements.
4. Technological Development and Lunar Landing Capability
Concerning the issue that "the U.S. can't return to the moon despite significant technological advances", this is actually due to a shift in developmental goals. In 1969, the U.S. was primarily driven to reach the moon to compete with the Soviet Union and demonstrate national power. However, afterward, the U.S. Congress and the public generally believed that space exploration was unrelated to everyday life, and with the U.S. engaged in the Vietnam War, the budget for space exploration was often reduced, and the space program was directed towards more Earth-focused objectives.
5. Question about Apollo 17 Crew Egress Photo
For the question about Apollo 17 crew members not wearing spacesuits when exiting the module in photographs, we need specific images and more information for a detailed analysis. Generally, for the safety of astronauts, they are strictly required to wear spacesuits during all stages of a moon mission.
6. The Petrified Wood Issue
In 2009, researchers at the RIJKS museum in Amsterdam, the Netherlands, discovered that their "moon rock" was actually petrified wood. This sample was given as a gift to the then Dutch Prime Minister Willem Drees by the Apollo 11 astronauts during their visit to the Netherlands in 1969. A detailed investigation into this alleged switch is still pending. However, it's worth noting that over a hundred countries received moon rock samples from the U.S., and no other country reported receiving fake moon rocks.
7. Communication Issues
Regarding the development of mobile communication technology and the issue that "live broadcasting between Earth and the moon is not possible", in reality, although communication technology from the era of vacuum tubes is backward compared to modern times, we were still able to establish communication between Earth and the moon. The latency in communication seen by the audience during the live broadcast of the moon landing was minimal, as scientists and engineers of the time used a range of specialized techniques and methods to reduce communication delay.
8. Other Misconceptions:
Common misconceptions include the absence of an impact crater and the capability of the Apollo landing computer. The Apollo lunar lander used reverse thrust to gently touch down on the lunar surface, avoiding an impact crater. As for the landing computer, it was purpose-built to handle the specific needs of the mission.
9. Concrete Evidence:
Beyond mere debunking, the authenticity of the moon landing is fortified by an abundance of evidence: thousands of photos, live broadcasts, lunar rock samples, and the still-in-use laser reflectors left by the Apollo astronauts, not to mention the undeniable images of Apollo landing sites captured by lunar orbiters.
The existence of moon landing conspiracy theories underlines the need to promote scientific literacy and critical thinking. They are a stark reminder of how misinterpretation and miscommunication can obfuscate truth and belittle our collective achievements in space exploration.
The moon landing is not just a historical event. It is a testament to the boundless courage of humanity, a celebration of our ceaseless innovation, and a beacon of our relentless pursuit of the universe's mysteries. Today, I urge us all not to surrender to conspiracy theories but to honor the pioneering spirit that the Apollo missions symbolize. It's a towering beacon, a testament to our shared journey of scientific discovery. We must recognize that questioning is the pulse of scientific advancement, but such doubts must be grounded in evidence, not baseless suppositions. Let us continue to pay tribute to the unyielding courage and indomitable resilience of the many scientists, engineers, and astronauts. Their toil, their commitment, their unflinching determination have lit the beacon on our path to the cosmos.
重访月球登陆: 捍卫美国宇航局的辉煌成就和科学探索的精神
作者:蒋红涛, 2023年7月18日
当我们纪念阿波罗月球登陆的54周年之际,我们的思绪不由自主地回到了那个非凡的日子——1969年7月20日。在那一天,美国宇航员尼尔·阿姆斯特朗勇敢的迈出了登月舱,首次踏上了月球表面。这一开创性的事件不仅展示了人类创新的光辉,也成为了科学进步的永恒灯塔。
然而,在这个充满了数字喧嚣和错误信息乱传的时代,存在着一群质疑月球登陆真实性的人。他们声称美国宇航局 (NASA) 登陆月球的重大成就是一次精心策划的骗局,试图对我们共享的历史投下怀疑的阴影。作为在NASA工作超过20多年的科学家,我原本不觉得有必要花时间去理会这些阴谋论。但今天在飞机上有几个小时的时间,我决定用这些时间来阐述几点。借助我多年积累的科学严谨性和亲身经验,对这些阴谋论进行反驳并不难,主要是为了维护美国宇航局的成就以及科学探索的精神。
让我们来探讨月球登陆阴谋论的主要观点。大部分的论证都集中在对照片和录像中出现的异常现象的质疑,例如阴影的不一致、在真空中飘扬的美国国旗,以及月球天空中星星的显著缺失。有人甚至指出,冷战时期的政治紧张环境意味着月球登陆可能是赢得冷战胜利的一种策略。对这些论点进行科学和历史的深度分析,是揭示其错误的关键。
1. 摄影和电影中的“异常”
首先,对阿波罗图像进行严谨的检查需要对月球环境和摄影原理有深入的理解。例如,那些被称为“异常”的阴影实际上是由于月球表面地形和广角镜头畸变的结果,这可以通过实验来证实。因此,将“异常”用来暗示多个光源的说法是错误的。此外,科学实验也表明,月球表面的光反射或“反照率”可以解释那些看似奇怪的阴影现象。
关于被阴谋论者质疑的“飘扬”的美国国旗,其实这是真空中的国旗设计效果。国旗被一个水平杆支持,在宇航员安装时,国旗受到了惯性运动的影响。在月球无空气的环境下,这种皱褶效应会持续,而在地球上,空气阻力会迅速停止这样的运动。电视节目“神秘破解者” (“MythBusters” https://en.wikipedia.org/wiki/MythBusters)曾在真空中成功地复制过这一现象。
再有,那些“消失的星星”是由于月球白天的条件和相机设置造成的。阳光的亮度,以及为了捕捉照明良好的宇航员和设备而设置的相机参数,使得微弱的星星变得难以被捕捉。考虑到月球没有大气散射,物体会直接反射阳光。如果胶片的曝光时间足够长以显示星星,那将会导致过度曝光,从而使宇航员和月球登陆设备的图像过亮而模糊。
2. 历史背景
将月球登陆看作是冷战中的骗局,以此在太空竞赛中取胜的观点,过于简化并忽视了关键的历史事实。到1969年,美国已经通过一系列的成就,例如首次太空行走,证明了其太空技术的实力。此外,登月计划涉及了数以万计的科学家,工程师,以及技术和媒体工作人员,如果真存在这种大规模的欺诈,不可能在半个世纪以上的时间里依然能保持秘密。况且,冷战期间美国的主要竞争对手苏联也密切关注了NASA的阿波罗任务,却从未对其合法性提出质疑。
3. 母带和图纸丢失的问题
对于阴谋论者提出的“母带丢失”的问题,实际上,阿波罗登陆时使用的是慢速电视转播。丢失的是母带转出的第一批动态胶卷,而非母带本身。在经过一段时间的搜索后,这些资料已经被找到,并且重新修复并公开。
至于“土星五号火箭图纸丢失”以及“为何后续未再使用土星五号”的问题,事实上,土星五号火箭的实体至今仍在公开展示之中。阿波罗计划结束后,土星五号火箭在进行太空实验室任务中得到了使用。在地球轨道任务中,我们不需要像土星五号那样的大型火箭,就如同我们去便利店买东西并不需要坐飞机一样。此外,从现代科技的角度看,土星五号的设计已经相对过时。当前使用的火箭,如三角洲4号运载火箭、猎鹰9号运载火箭等,既安全又可靠,而且提供了更多的选择,可以满足不同的太空任务需求。
4. 科技发展与登月能力
关于“美国在科技大发展的情况下反而无法登月”这一问题,其实这是因为发展目标的转变。1969年,美国的登月目标主要是为了与苏联竞争,展示国力。然而,在那之后,美国国会和公众普遍认为太空探索与民生无关,并且美国还在参与越战,因此太空探索预算常常被削减,太空计划被要求转向更加关注地以上,我们通过科学和历史的剖析,可以看出阿波罗登陆月球阴谋论的诸多漏洞,与事实严重不符。
5. 阿波罗17号人员出舱照的疑问
对于阿波罗17号照片中的宇航员在返回地球时未穿宇航服的疑点,我们需要具体的图片和更多信息才能进行详细分析。一般情况下,出于对宇航员生命安全的考虑,登月任务的所有阶段,宇航员都会严格穿着宇航服。
6. 石化木头的问题
2009年,荷兰阿姆斯特丹RIJKS博物馆的研究人员发现他们收到的“月球岩石”实际上是石化木头。这块样品是在1969年阿波罗11号宇航员访问荷兰时,作为礼物赠送给当时的荷兰首相威廉·德雷斯的。对于这次偷梁换柱的情况,具体的调查尚待进行。然而,值得注意的是,当时有超过一百个国家收到了美国送的月球岩石样本,而其他国家并未报告他们收到的月球岩石是假的。
7. 通信问题
关于移动通信技术的发展以及“地球与月球之间无法进行实时直播”的问题,实际上,尽管电子管时代的通信技术与现代相比较落后,但我们依然能够实现地球与月球之间的通信。当时观众在电视上看到的登月直播的通信延迟极小,这是因为当时的科学家和工程师使用了一系列专门的技术和方法来降低通信延迟。
8. 其他的疑虑
除此之外,还有一些常见的疑虑,如阿波罗月球登陆器在着陆时未留下撞击坑或搅动尘土的现象,以及关于阿波罗登陆计算机计算能力微小是否能够完成登陆所需的复杂计算等问题。针对前者,阿波罗登陆器在降落过程中运用了反向推力以实现柔和的降落,这就防止了撞击坑和尘土扬起的产生。我们的喷气推进实验室在1966年实现无人器软着陆月面的过程中已进行过多次试验,可以证明这一点。关于计算机能力的问题,我们要记住,技术并不是线性发展的,它是为其时代的需求服务的。1969年的月球登陆任务相对简单,与今天的太空任务相比,这不需要进行复杂的计算。
9. 实证证据
除了反驳阴谋论,我们还有大量证据证明月球登陆的真实性。这些证据包括数千张照片、各个国家全球直播的视频、以及382公斤的月球岩石样本,这些样本经过全球科学家的检验并确认来自外太空。阿波罗任务宇航员在月球上留下的反射镜至今仍在激光测距实验中使用,以供任何人独立验证登陆。此外,多个月球勘测轨道飞行器以及在月球上空飞行的其他飞船拍摄的照片为阿波罗登陆地点和留在月球表面的设备提供了无可争议的证据。
总的来说,月球登陆阴谋论提醒我们必须坚守科学素养和批判性思维。这些阴谋论给我们提供了一个生动的例子,展示了对科学事实的误解和误传如何使真相变得模糊,并贬低了我们太空探索的无限潜力。
月球登陆展示了人类的勇气、创新力和对宇宙无尽的探索精神。美国宇航局的拓荒精神拓宽了我们的视野,并增进了我们的集体智慧。
今天,我要强调的是,我们不应被质疑的阴谋论所左右,而应高度赞扬美国宇航局的阿波罗登月创举,视其为我们科研探索历程中的一座卓越的里程碑。我们需要铭记,质疑是科学发展的动力源泉,但怀疑必须建立在证据之上,而不是空洞的假设。最为重要的是,我们要深深尊敬那些无数的科学家、工程师和宇航员们的勇气和毅力,正是他们精细、艰巨的工作和坚韧不屈的努力,为我们照亮了通往宇宙的道路。
