10 years of moon pics: NASA explains why moon shines in red, blue and even purple

Moon has since forever been the most beautiful jewel of the night sky on Earth. The planet’s constant companion undergoes a cyclic change in its appearance, all thanks to the periodic reflection of light of the Sun. 

This change in shape, however, is not the only different form that the moon takes in the night sky.


As you might have noticed, the moon has lately been observing a completely different colour than its usual grey. This, however, is not the only colour change that the moon displays. In fact, an astrophotographer has managed to capture the various shades of moon experienced by the observers on Earth over the last 10 years. NASA now clears that these changes in colour shades are caused by the Earth’s atmosphere.


Moon

In a recent post shared by the US space agency, a picture depicts the several shades of the moon, ranging from Purple to Red and even Blue. In the post, NASA says that although the moon appears to be “brown-tinged gray” from space, Earth’s atmosphere can have varying effects on the same, making the moon appear different from its real colour.


At times, it appears red, as NASA explains that “a red or yellow colored moon usually indicates a moon seen near the horizon.” This is because the blue light gets scattered over the long distance it takes for the moonlight to reach from the horizon to Earth’s surface, thanks to the atmospheric particles on the way, including dust.


The rare Blue moon, on the other hand, lights up the night sky when there are larger dust particles present in the atmosphere. This means that light from the Blue spectrum can reach the surface without getting dispersed on the way.


It is yet unclear as to how the moon turns Purple but NASA guesses that it should be “a combination of several effects.”

Among the collection, the last image portrays the total lunar eclipse of 2018 July. During the eclipse, the moon which was covered in the Earth's shadow, appears to be a faint red. The reason for this is cited to be the “light refracted through air around the Earth.”


The images have been collated by Marcella Giulia Pace, a primary school teacher and an astrophotography enthusiast in Italy. It took Pace 10 years to capture all the shades of the moon as seen in the image.


In its post, NASA explains that the next full moon, known by some as the Beaver Moon, will occur at the end of this month until it goes back to its new moon stage by the middle of December.

Indian origin NASA researcher discovers Jupiter’s moon Europa glows in the dark

 We all know that Jupiter is the largest planet in our solar system. Moreover, it is also the planet with 79 moons. 

The gargantuan planet is far from being a hospitable planet with its surface filled with gases and liquids. However, researchers believe that one of its moons, Europa could possess life. 


Researchers have discovered that strong radiation from the large planet causes Europa’s dark side to glow in the dark, making scientists believe that it could sustain simple life forms.


This is according to a study published in the journal Nature Astronomy. This outcome was a result of several experiments conducted by NASA scientists to understand the effects of Jupiter’s radiation on the chemical composition of Europa. 


For this experiment, they built an ‘ice chamber’ at JPL in Pasadena, California. The chamber consisted of chemicals that scientists believe are found on the Moon. They then exposed the moon to a beam of high-energy electrons to simulate Jupiter’s radiation. Scientists found that every time the radiation hits the chemicals, it glows. And the glow went off the moment the beam was turned off. 



Later, scientists changed the chemicals to simulate an environment mixed with ice on Europa’s surface with sodium chloride (aka salt) and magnesium sulfate (Epsom salt) and saw that the ice glows in different intensities and in different colours like green, blue and even white. 


JPL's Murthy Gudipati, the lead author of the study, said “If Europa weren't under this radiation, it would look the way our moon looks to us -dark on the shadowed side. But because it's bombarded by the radiation from Jupiter, it glows in the dark.”


He added, “We were able to predict that this nightside ice glow could provide additional information on Europa's surface composition. How that composition varies could give us clues about whether Europa harbours conditions suitable for life.”


Now NASA is set to launch the Europa Clipper mission in the 2020s that could help prove this at the same time help us better understand the moon, while also seeing if it is capable of hosting life.

India-born NASA engineer thanks her parents for their struggles and her success

Parents strive hard to offer a lifestyle for their children that they never could receive -- be it with respect to toys or things kids demand to help them study and progress to better heights. 

And this only gets more challenging if you’re a migrant parent trying to earn your living in a different state or nation where costs constantly keep on piling up and compromises are made at every corner. 


However, despite this, parents don’t give up and help the child flourish in life, and give them the career they desire. And while browsing LinkedIn I stumbled across a post by one Akshita Kapasiawala who recently got appointed at NASA as a system engineer. In the post, she shared the hardships her parents had to go through to bring her to this stage in life and how she’s immensely grateful for it.  


Facebook: Akshita K


She said in the post, “I came to America 25 years ago from India with my parents. They came to this foreign land with just the clothes on their back and one goal: provide a better life for their children. I grew up watching my dad work 12-15 hours a day to single-handedly support a family of five.”


She shared how her parents tried to save money wherever they could to make ends meet, “We never went on family vacations, camping, movies, or even a weekend getaway. If we ever wanted something, we were told “No, it’s too expensive” or “Maybe when it’s on sale.” My mom was a conservative stay-at-home mom who couldn’t speak English and had no friends or family to help her with three children. They both struggled, and they struggled a lot.”


However, she said that all this struggle made her appreciate what she was gifted with and dream bigger, “This struggle taught me something. It taught me to appreciate what little we have in life and to never be afraid to dream big. It taught me to take risks. It taught me to be self-motivating. It taught me to be a fighter. Most importantly, it taught me to never allow failure to define who I am.”


She added, “Five years ago, I would have laughed at the thought of ever getting a job at NASA. A month ago, I received an offer from Marshall Space Flight Center for an engineer position. In that moment I realized that dreams do come true. Dream hard, and dream big. Don’t let anyone ever tell you otherwise.”


Reading her story, most of us would be able to relate to the hardships our parents took to get us where we are. And this was also seen by people who read her post.


Akshita K has completed her Bachelors in Science (Mechanical Engineering) From Rutgert’s University. She has also worked at Naval Surface Warfare Centre as a Junior System’s Modeler. She's also interned at India’s Larsen and Toubro as well as received NDT Level 2 Training at Modi Institute of Non-Destructive Testing. 


At NASA she is responsible for NASA’s Human Landing System which involves working on software extensive work as well as planning and maintenance of the system.


As said by Khalil Gibran, “Parents are like bows, children, like arrows. The more the bow bends and stretches, the farther the arrow flies.  I fly, not because I am special, but because they stretched for me.”

NASA removes offensive words to name stars to 'make science more inclusive'

Nasa has promised to “reexamine” its use of unofficial terminology for stars and other cosmic objects after it was revealed several offensive and “racist” names had been attached to stars.

In a statement posted to their website, Nasa admitted that some unofficial cosmic nicknames it had been employing were “insensitive” and “actively harmful”.

They wrote:

Distant cosmic objects such as planets, galaxies, and nebulae are sometimes referred to by the scientific community with unofficial nicknames.

As the scientific community works to identify and address systemic discrimination and inequality in all aspects of the field, it has become clear that certain cosmic nicknames are not only insensitive, but can be actively harmful.


NASA is examining its use of unofficial terminology for cosmic objects as part of its commitment to diversity, equity, and inclusion.

As a first step, the agency has announced they will no longer refer to a planetary nebula officially titled ‘NGC 2392’ as the ‘Eskimo Nebula’ because the term is ‘colonial’, with a “racist history, imposed on the indigenous people of Arctic regions”.

Similarly, the nickname of ‘Siamese Twins Galaxy’ for a pair of spiral galaxies in the Virgo Galaxy Cluster will be retired from use.

Instead Nasa says it will only use “International Astronomical Union designations” to refer to cosmic objects where nicknames are inappropriate.

The agency says it won’t be banning the use of nicknames full stop – they’re a useful way to make the cosmos accessible.

But it is stressing that a thoughtless nickname can be “harmful and detract from the science”.

Nasa has also pledged to work with diversity and inclusion experts to provide recommendations on other aspects of their star-naming process.

Of course, some people accused NASA of bending to a ‘woke’ agenda.

But others said the decision had come from Nasa staff and was the right one.
Who votes we just call them what they are: big ol' balls of gas.

Catchy, right?

Air pollution levels in North India at "20-year low" amid lockdown: NASA

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).

The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. 

The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. 

This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

Coronavirus: Space images reveal drastic fall in pollution over China as factories closed

‘This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event,’ says Nasa scientist

Satellite images show a dramatic drop in pollution over China after the coronavirus outbreak shut down swathes of the country’s industry and travel.

US space agency Nasa said the change was at least partly related to the economic slowdown caused by efforts to contain the virus.

Nasa maps show how levels of nitrogen dioxide, a toxic gas from vehicles, power plants and factories, plummeted after the mass quarantine, compared with before.

Scientists have previously found the coronavirus wiped out at least a quarter of China’s emissions of damaging greenhouse gases in just two weeks in mid-February.

Closing industrial plants and asking people to stop at home has led to sharp drops in the burning of fossil fuels — a key cause of the climate crisis — in the world’s largest greenhouse gas producer.

China, where the outbreak began, has nearly 80,000 cases of coronavirus, by far the largest number of any country, with nearly 2,900 deaths.

Nasa’s maps compare pollution levels between the first three weeks of the year and 10-25 February.
This year, pollution levels did not rise again after Chinese new year, unlike last year (Nasa)

The space agency’s scientists said the fall in pollution was first apparent near Wuhan, the source of the outbreak, but eventually spread across the country.

“This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event,” said Fei Liu, an air quality researcher at Nasa’s Goddard Space Flight Centre.

She said she had seen a decline in nitrogen dioxide levels during the economic recession of 2008 but said that decrease was more gradual.

Incredible infrared pictures taken from space show Australia burning as plumes of thick smoke are sent soaring into the atmosphere

Infrared pictures taken from space show thick plumes of toxic smoke billowing from the catastrophic bushfires in Australia.

Satellite images taken on Saturday showed wildfires burning around East Gippsland and Kosciuszko National Park.

The eerie photos showed the scale of the blazes, after high winds and 46C heat on Saturday increased the ferocity of the fires. 

Officials confirmed more than 1,500 homes had been destroyed - 1,365 in NSW alone - with more than 300 fires still ravaging the parched land across the country.

Late on Saturday, thousands of residents in fire-ravaged Victoria were given evacuation orders as out-of-control blazes threatened several towns.

Up to 24 communities were isolated on Saturday night as the Princes Highway closed between Orbost in southern Victoria and the NSW border, the Herald Sun reported. 

Cann River was evacuated via an old road to Orbost as an out-of-control fire threatened lives and homes.
A bus and 40 cars convoyed out of the town at 3pm.

Residents in Freeburgh, Harrietville, Smoko and Wandiligong were also told their homes and lives are in danger as fires spread due to the high winds. 

Of around 100,000 residents in East Gippsland, 70 per cent have fled.

Residents over in NSW were begged to limit their energy use, with people asked to not turn on dishwashers or washing machines.

It came as key lines in the Snowy Mountains were ravaged by fires, causing around 15,000 to lose power.

Fires continued to spread in the state overnight, with residents of Kangaroo Valley, a lush green area west of the popular tourist town of Berry, being told it's too late to leave.

As of early Sunday morning, there were 150 bushfires in NSW - seven at emergency level - and 50 fires burning in Victoria - 13 of which are at emergency level. 

Evacuations are underway and emergency alerts are in place in NSW, Victoria and South Australia as authorities predict the devastating bushfires will continue burning until at least March. 

At least 23 people have been killed in blazes across the country since the bushfire season began in October, there are six people still missing in fire-affected regions

NEW SOUTH WALES/ACT
  • Two people are unaccounted - one near Bodalla on the South Coast and the other person from Bombala near the Victorian border
  • At least 150 bushfires were burning in NSW on Sunday

NASA finds India’s Vikram moon lander crash site, with amateur’s help

Since India lost contact with the spacecraft in September, the precise location of its crash has been a mystery.

NASA has found pieces of Vikram, a small spacecraft that India attempted to land on the moon in September. They did it with the help of an engineer from India who scoured the lunar surface in his spare time.

Vikram was part of India’s Chandrayaan-2 mission to the moon, which launched in July. If the spacecraft had reached the surface in one piece on Sept. 7, India would have been only the fourth country to successfully put a lander on the moon.

But less than two miles above the surface, Vikram veered from the planned descent trajectory and fell out of radio contact.

India’s space agency said the next day that it had located the lander. But it never published any images of the hard landing site taken by the mission’s accompanying orbiter, which remains in operation and is carrying out a scientific mission that will last for years.

A NASA spacecraft, the Lunar Reconnaissance Orbiter, has passed over the mission’s intended landing site, on a high plain near the south pole, several times since September. But initial analyses of the images did not reveal an obvious impact scar comparable to the Beresheet lander launched by Israel this year, which crashed in April. NASA scientists noted that the spacecraft might have been hidden in the shadows.

A lot of people were looking, including Shanmuga Subramanian, an Indian computer programmer and mechanical engineer.

“The crash landing of Vikram rekindled an interest in the moon not only for me and others also,” he wrote in an email. “I think even if Vikram had landed and sent some images, we would have never had such interest. For the first few days I was scanning the images randomly and there were lot of false positives.”


After reviewing the last known velocity and position of Vikram, Mr. Shanmuga shifted where he was looking. He noticed a white speck on the lunar surface that was about two-thirds of a mile from where Vikram was supposed to have set down.

That speck was not visible in an earlier image. He wondered if the crash might have buried the lander in the lunar soil.


Mr. Shanmuga reported what he had found to NASA and scientists working with the Lunar Reconnaissance Orbiter’s camera, who confirmed his finding and scoured the surrounding area. Comparing images taken before Vikram’s landing attempt and those taken on Nov. 11, they were able to identify the impact point about 2,500 feet to the southeast of the planned touchdown site, and a spray of debris emanating outward.

An image generated from the ratio of the brightness in the before and after images more clearly shows how the impact of Vikram disturbed the lunar soil.  Credit... NASA/Goddard/Arizona State University

The pieces of debris were not much bigger than the minimum of what the camera could make out. The resolution of the camera was about 1.3 meters per pixel; the three largest pieces of debris were about two pixels by two pixels in size and cast a one-pixel shadow, NASA said.

Chennai engineer helps NASA locate Vikram lander

NASA's Lunar Reconnaissance Orbiter mission of Goddard Space Flight Centre has credited Shanmuga Subramanian, a mechanical engineer in India, for the discovery in an official email.

A Chennai engineer has helped American space agency NASA to find pieces of Vikram lander on moon's surface. 
NASA's Lunar Reconnaissance Orbiter (LROC) mission of Goddard Space Flight Centre has credited Shanmuga Subramanian, a mechanical engineer in India, for the discovery in an official email.

"Thank you for informing us of your discovery of debris from the Vikram lander. The LROC team confirmed that the location does exhibit changes in images taken before and after the date of the landing. Using this information the LROC team did additional searches in this area and located the site of the primary impact as well as other debris around the impact location and has announced the sighting on the NASA and ASU pages where you have been given credit for you observation," John Keller, Deputy Project Scientist, LROC, said. 

Vikram was part of India’s Chandrayaan-2 mission to the moon, which launched in July.

If the spacecraft had reached the surface in one piece on September 7, India would have been only the fourth country to successfully put a lander on the moon.  

Subramanian had contacted NASA in October, but it took time for the American space agency to be certain of its interpretation of the observation as well as making sure that all the stakeholders had an opportunity to comment before they would announce the results. 


Subramanian told Express that he was happy that his work got the due recognition.

Amazon fires: Angola and DR Congo 'have more blazes'

The severity of fires in the Amazon has prompted a global outcry. But, amid the protest, some are questioning how this compares with the rest of the world, with surprising results.

The issue has got people checking out Nasa's maps of fires around the world. When you look at the map from Sunday, it clearly shows more fires burning in central Africa.

Over a period of two days last week Angola had roughly three times more fires than Brazil, according to data Bloomberg news agency obtained from Weather Source.

The data said there were 6,902 fires in Angola and 3,395 fires in neighbouring Democratic Republic of Congo, compared with just 2,127 fires in Brazil.

This has shocked many on Twitter.



A Brazilian tweeter hit out at French President Emmanuel Macron, who described the fires in the Amazon as an "international crisis", accusing him of ignoring blazes in Africa.


On Monday Mr Macron announced that the leaders of the G7 - Canada, France, Germany, Italy, Japan, the UK and the US - would release $22m (£18m) to help fight fires in the Amazon rainforest.

But then he drew attention to the African fires.

"The forest is also burning in sub-Saharan Africa" he tweeted.

Mr Macron added that he was "considering the possibility of launching a similar initiative" in sub-Saharan African to that announced for the Amazon.


The vital bits of information the maps from Nasa do not show is whether they are grassland or forest fires and how big the fires are.

Observers point to similar fires two years ago which, Nasa said, appeared to have been started on purpose.

The suggestion is that farmers have cut down some of the vegetation and set fire to the rest in order to clear the land to plant crops.

The farming technique, known as slash and burn, is controversial as environmentalists warn it can lead to deforestation, soil erosion and a loss of biodiversity.

But it is the cheapest way to clear land, has the advantage of killing disease and the ash provides nutrients for future crops.

So burning fields remains popular among farmers.

It happens every year ahead of the rainy season, which is expected to start in Angola and DR Congo in the next month or so. This could go some way to explaining why the fires have not attracted much attention.

One giant ... lie? Why so many people still think the moon landings were faked

It all started with a man called Bill Kaysing and his pamphlet about ‘America’s $30bn swindle’ ...

It took 400,000 Nasa employees and contractors to put Neil Armstrong and Buzz Aldrin on the moon in 1969 – but only one man to spread the idea that it was all a hoax. His name was Bill Kaysing.

It began as “a hunch, an intuition”, before turning into “a true conviction” – that the US lacked the technical prowess to make it to the moon (or, at least, to the moon and back). Kaysing had actually contributed to the US space programme, albeit tenuously: between 1956 and 1963, he was an employee of Rocketdyne, a company that helped to design the Saturn V rocket engines. In 1976, he self-published a pamphlet called We Never Went to the Moon: America’s Thirty Billion Dollar Swindle, which sought evidence for his conviction by means of grainy photocopies and ludicrous theories. Yet somehow he established a few perennials that are kept alive to this day in Hollywood movies and Fox News documentaries, Reddit forums and YouTube channels.

Despite the extraordinary volume of evidence (including 382kg of moon rock collected across six missions; corroboration from Russia, Japan and China; and images from the Nasa Lunar Reconnaissance Orbiter showing the tracks made by the astronauts in the moondust), belief in the moon-hoax conspiracy has blossomed since 1969. Among 9/11 truthers, anti-vaxxers, chemtrailers, flat-Earthers, Holocaust deniers and Sandy Hook conspiracists, the idea that the moon landings were faked isn’t even a source of anger any more – it is just a given fact.

The podcast kingpin Joe Rogan is among the doubters. So too is the YouTuber Shane Dawson. A sociology professor in New Jersey was exposed last year for telling his students the landings were fake. While Kaysing relied on photocopied samizdat to alert the world, now conspiracists have the subreddit r/moonhoax to document how Nasa was “so lazy” it used the same moon rover for Apollo 15, 16 and 17; or how “they have been trolling us for years”; or to bring up the fact there is “one thing I can’t get my head around ...”

“The reality is, the internet has made it possible for people to say whatever the hell they like to a broader number of people than ever before,” sighs Roger Launius, a former chief historian of Nasa. “And the truth is, Americans love conspiracy theories. Every time something big happens, somebody has a counter-explanation.”

It turns out British people love conspiracy theories, too. Last year, the daytime TV show This Morning welcomed a guest who argued that no one could have walked on the moon as the moon is made of light. Martin Kenny claimed: “In the past, you saw the moon landings and there was no way to check any of it. Now, in the age of technology, a lot of young people are now investigating for themselves.” A recent YouGov poll found that one in six British people agreed with the statement: “The moon landings were staged.” Four per cent believed the hoax theory was “definitely true”, 12% that it was “probably true”, with a further 9% registering as don’t knows. Moon hoaxism was more prevalent among the young: 21 % of 24- to 35-year-olds agreed that the moon landings were staged, compared with 13% of over-55s.

Kaysing’s original queries are fuelling this. One is the fact that no stars are visible in the pictures; another is the lack of a blast crater under the landing module; a third is to do with the way the shadows fall. People who know what they are talking about have wasted hours explaining such “anomalies” (they are to do with, respectively, camera-exposure times, the way thrust works in a vacuum and the reflective qualities of moondust). Yet until his death in 2005, Kaysing maintained that the whole thing was a fraud, filmed in a TV studio. “It’s well documented that Nasa was often badly managed and had poor quality control,” he told Wired in 1994. “But as of 1969, we could suddenly perform manned flight upon manned flight? With complete success? It’s just against all statistical odds.”

He was right about that at least. When the Soviets launched Sputnik 1 in October 1957 (followed one month later by Sputnik 2, containing Laika the dog), the US space programme was all but non-existent. Nasa was founded in 1958 and managed to launch Alan Shepard into space in May 1961 – but when John F Kennedy announced that the US “should commit itself to achieve the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth”, it seemed a stretch. By the mid-60s, Nasa was consuming more than 4% of the US federal budget, but while the Soviets were achieving more firsts – the first woman in space (1963), the first extra-vehicular activity, ie spacewalk (1965) – the Americans experienced various setbacks, including a launchpad fire that killed all three Apollo 1 astronauts.

If you have ever been to the Science Museum in London, you will know that the lunar module was basically made of tinfoil. Apollo 8 had orbited the moon in 1968, but, as Armstrong remarked, correcting course and landing on the moon was “far and away the most complex part of the flight”. He rated walking around on the surface one out of 10 for difficulty (despite the problems he had with the TV cable wrapping around his feet), “but I thought the lunar descent was probably a 13”.

That is until you compare it with the difficulty of maintaining a lie to the entire world for five decades without a single slip from any Nasa employee. You would also have to imagine that 2019-era special effects were available to Nasa in 1969 and not one of the 600 million TV viewers noticed anything amiss. Stanley Kubrick’s 2001: A Space Odyssey (1968) is a decent indication of what Hollywood special effects could do at the time – and it’s extremely shonky. It genuinely was simpler to film on location.

If we pass over “World war two bomber found on moon” – a Sunday Sport front page from 1988 – the moon-hoax theory entered the modern era in 2001, when Fox News broadcast a documentary called Did We Land on the Moon? Hosted by the X-Files actor Mitch Pileggi, it repackaged Kaysing’s arguments for a new audience. Launius, who was working at Nasa at the time, recalls much banging of heads against consoles. “For many years, we refused to respond to this stuff. It wasn’t worth giving it a hearing. But when Fox News aired that so-called documentary – stating unequivocally ‘We haven’t landed on the moon’ – it really raised the level. We began to receive all kinds of questions.”

Most of the calls came not from conspiracists, but from parents and teachers. “People were saying: ‘My kid saw this, how do I respond?’ So, with some trepidation, Nasa put up a webpage and sent out some materials to teachers.”

A particular bugbear in the Fox News documentary was a poll claiming that 20% of Americans believed the moon landing was faked. Launius says that polls tend to put the figure at between 4% and 5%, but it’s easy to phrase poll questions to achieve a more eye-catching result. “Every time there’s a hearing in a serious periodical – even an offhand comment in a movie – it just seeds this stuff.” He cites a scene in Christopher Nolan’s Interstellar (2014) in which a schoolteacher informs Matthew McConaughey’s character that the moon landings were hoaxed in order to win the propaganda war against the Soviet Union. “It’s a throwaway in the film. But it really did churn up a big response.”

Oliver Morton, the author of The Moon: A History for the Future, believes the persistence of the moon hoax isn’t surprising. Given an implausible event for which there is lots of evidence (Apollo 11) and a plausible event for which there is zero evidence (the moon hoax), some people will opt for the latter. “The point of Apollo was to show how powerful the American government was in terms of actually doing things,” he says. “The point of moon-hoax theory is to show how powerful the American government was in terms of making people believe things that weren’t true.” But the hoax narrative was only really possible as Apollo never led anywhere – there were no further missions after 1972. “As the American mind turns back to paranoia in the 1970s, it becomes more pleasing to believe in this,” he says.

James Bond has to take a small share of the blame. In Diamonds Are Forever (1971), Sean Connery busts into a Nasa facility by way of a Las Vegas casino. A chase ensues across a film set dressed up to look like the moon, complete with earthbound astronauts. But here it’s more like a visual joke, a way of justifying a moon buggy chase across the Nevada desert. By the time of Peter Hyams’ Kaysingian conspiracy thriller Capricorn One (1978), the idea that the government was fooling everyone was no laughing matter. Here it’s about a Mars mission that goes wrong. The authorities opt to fake it and kill the astronauts (one of whom is played by OJ Simpson) to prevent them revealing the truth. In the post-Watergate era, the idea that the government could lie on this scale had become much more plausible.

Apollo marked a turning point between the optimism of the 60s and the disappointments of the 70s. “We can put a man on the moon so why can’t we do X?” became a common refrain. As Morton says: “Yes, the government can set itself an extraordinary goal and go on to achieve it, but that doesn’t mean it can win the war in Vietnam, or clean up the inner cities, or cure cancer or any of the things that Americans might have actually wanted more. The idea that the government isn’t really powerful, it just pretends it is – you can see how it feeds into the moon hoax.”

Moon-hoax theories tend to be about what didn’t happen rather than what did. Conspiracists are divided on whether the earlier Apollo, Mercury, Gemini and Atlas missions were also fakes, whether Laika or Yuri Gagarin ever made it into space, and what role Kubrick played. But while the first generation of lunar conspiracists were motivated by anger, these days it’s more likely to be boredom. The line between conspiracy and entertainment is far more blurry.

Still, while irritating for those involved – Buzz Aldrin punched moon conspiracist Bart Sibrel in 2002 – in one sense the conspiracy idea is harmless, at least compared with misinformation about vaccinations or mass murders. Morton notes that it is one of the few conspiracy theories that isn’t tainted by antisemitism. Nor does it seem to be one to which Donald Trump, the ultimate product of news-as-entertainment, subscribes. The dynamics of the modern internet have clearly not helped: look up Apollo videos on YouTube and before long moon-hoax documentaries start lining up in the autoplay queue. But there is little evidence that Russian disinformation agents have spread moon conspiracies as they have anti-vaxxing propaganda, for example. Although, if you think about it, it would make perfect sense for them to do so: a neat way of restoring Russian prestige while establishing continuity between the cold war and the information wars.

Then again, the USSR had the means to expose the Americans at the time; it was listening in. “We were there at Soviet military base 32103,” the Russian cosmonaut Alexei Leonov recently recalled. “I swear to God we sat there with our fingers crossed. We hoped the guys would make it. We wanted this to happen. We knew those who were on board and they knew us, too.”

The growing strength of the hoax theory is “one of the things that happens as time recedes and these events are lost”, laments Launius. “We’ve seen it with the second world war and the Holocaust. A lot of the witnesses are passing from the scene and it’s easy for people to deny that it took place. Who is left to counteract things that are untrue? Mythologies develop and become the dominant theme.”

Perhaps the hardest thing to believe in is the idea that humans might have accomplished something transcendent – something that even brought out the best in Nixon. “Because of what you have done, the heavens have become part of man’s world,” he said in his telephone call to Aldrin and Armstrong on the moon. “And as you talk to us from the Sea of Tranquility, it inspires us to redouble our efforts to bring peace and tranquility to Earth.”

We have less faith in ourselves these days. Most moon conspiracists treat the whole thing as a joke, a rabbit hole to go down from time to time. Perhaps if Nasa returns to the moon – possibly as early as 2024, depending on Trump’s whims – it will be replaced in time by Mars conspiracies.

Still, you could see the persistence of the moon conspiracy as a compliment to the Apollo scientists. “In a way, the moon hoaxers are taking the Apollo missions far more seriously than most people do,” says Morton. “It’s a sign that they really care. They think that Apollo really mattered.” The truth is that the moon landings didn’t really change life on Earth. Not yet anyway.
