Apollo 18: Myths of the Moon Missions
Sept. 2, 2011 --
In the movie "Apollo 18," lost footage taken from what was the canceled Apollo 18 mission to the moon reveals a coverup. NASA buried the mission after astronauts encountered hostile life forms on the moon. The Apollo missions captured the imagination of a generation, so it's no small wonder that fictional accounts -- such as that of "Apollo 18" -- of what happened during NASA's golden age still find new angles on a rich history. Although the Apollo program is a technological and historical legend, as with most stories of heroes and triumph, there have been some embellishments and distortions along the way. Explore the myths, misconceptions and urban legends that color the history of the Apollo missions. (And good news for space enthusiasts: We're not even mentioning the delusion that the moon landing was a hoax.)
We begin with a myth of the Apollo era that was soon squashed after astronauts returned home. Prior to the first successful landing of astronauts on the lunar surface, NASA scientists theorized that their astronauts may have been contaminated with pathogenic microorganisms to which humans would have no resistance. The space agency even enforced a 21-day quarantine for astronauts returning from space. In this photo, Aldrin greets his visiting family via telephone while still constrained in the Mobile Quarantine Facility in Houston, Texas. Biomedical studies conducted following the quarantine period determined that neither the astronauts nor any of the living species that brought along on the mission, including plants and animals, suffered any adverse health effects as a direct result of exposure to lunar material.
"Apollo 18" hinges on the premise that the cancelled Apollo 18 mission was in fact carried out, but covered up after the space agency discovered the presence of hostile alien life on the lunar surface. We all know that in reality Apollo astronauts who landed on the moon never stumbled onto any lunar life. But did Buzz Aldrin, as he appears to claim in this interview for a documentary, spot a UFO while en route to the moon? As Aldrin would later go on to explain following the airing of these comments, not even close. What he actually saw, which he and his fellow astronauts immediately confirmed, was "one of the panels from the separation of the spacecraft from the upper stage."

The Million Dollar... Pen?
To paraphrase an old joke: When presented with the challenge of writing in a zero-gravity environment, the United States and the Soviet Union approached the same problem in two different ways. NASA spent millions of dollars developing and testing the space pen. The Russians, on the other hand, used a pencil. In reality, the space pen wasn't developed by NASA, but rather a private company that later sold its invention to both the U.S. and the U.S.S.R. A kernel of truth is hidden in this story, however. NASA originally used mechanical pencils and hired a private contractor to supply "34 units" at a price of $4,382.50 in 1965 (around $30,000 today). The public outcry against this purchase led NASA to the cheaper alternative designed by Fisher Space.
Why Was Armstrong First?
Everyone knows that Neil Armstrong was the first man to set foot on the moon, followed closely by Buzz Aldrin. But how many people know the reason why Armstrong was first? In one version of events, Armstrong was selected as the first man to set foot on the moon so that NASA could symbolically convey the message that civilians would be leading the charge with space exploration rather than the military. Aldrin had a long career with the Air Force prior to becoming an astronaut. This account, however, is a myth. For his part, Armstrong had spent time in the military before joining the public sector as a civilian. So why was he chosen first? The answer is much less complicated: It was his turn to be commander after rotating through as backup commander during Apollo 8.
Americans these days look back on the legacy of the space program with pride and admiration. This singular technological achievement is unrivaled to the day. Although Americans may look back fondly at that glorious era, their 1960s counterparts weren't quite as supportive. The Apollo program is widely believed to have been popular during its time, but polling data taken from the era suggest that simply wasn't the case. Throughout the entire era, surveys consisted showed that less than 50 percent of the American public favored the program. Even after Armstrong took his first steps on the moon in 1969, only 53 percent of American surveyed said the accomplishment was worth the cost, according to a report by Space.com.
Could the real reason astronauts haven't returned to the moon be because NASA has simply forgotten how? According to this rumor, propagated by writers including Terry Bisson and astronomer John Lewis in his book "Mining the Sky" in 1996, NASA simply lost its blueprints to the Saturn V rockets. NASA was quick to point out that microfilm of the blueprints is still in storage at Marshall Space Center. So why can't NASA rebuild the Saturn rockets? As explained in 2009 by NASA Lunar Science Institute director David Morrison, many of the companies that manufacture the parts that made up the Saturn V have since gone out of business and the parts are no longer available. Besides, rocket technology has advanced somewhat since the Apollo era.

As much as we'd all like to believe it's true, NASA did not invent Tang during the Apollo missions. In fact, the instant drink mix had been invented during the 1950s by General Foods Corporation. When NASA adopted it during John Glenn's initial venture into space and for subsequent journeys, the missions popularized the product. Given the kinds of innovations NASA dreamed up during the Apollo years, these misconceptions have become common. Other developments around the same era, such as Teflon and Velcro, are also falsely attributed to the space agency.
Space Pen Savior?
Would you believe the space pen was responsible for preventing Aldrin and Armstrong from being stranded on the moon? The Fisher Space Pen folks would like you to think that's the case, but that's not exactly how it happened. When Armstrong and Aldrin returned to the lunar lander after their historic space walks, the astronauts discovered the "the ascent engine's arming circuit breaker was broken off on the panel," according to Aldrin. In other words, a circuit needed to power the engines to get the Apollo 11 astronauts off the moon simply wasn't working. To complete the circuit, the astronauts didn't use a space pen but rather an ordinary felt-tip marker.
On March 17, scientists monitoring the moon for meteorite impacts spotted the biggest impact event to date: a space rock the size of a basketball slammed into the lunar surface at a speed of 56,000 miles per hour (90,000 km/hr), creating a new crater around 20 meters wide.
“On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium,” said Bill Cooke of NASA’s Meteoroid Environment Office in a statement over the weekend. “It exploded in a flash nearly 10 times as bright as anything we’ve ever seen before.”
Indeed, the flash was impressive — it unleashed the equivalent energy of 5 tons of TNT exploding and would have been visible to anyone casually looking at the moon, no telescope required.
The impact was captured by a NASA program monitoring impact events during “lunar meteor showers.” When small pieces of rock — meteoroids — hit the Earth’s atmosphere, they produce a bright streak of light as they burn up. These are “meteors.” On the moon, however, there is no atmosphere, so the meteoroids directly hit the lunar surface, creating an energetic flash.
These impact events occur with more regularity than expected.
For the past eight years, NASA telescopes have been surveying the moon’s surface, cataloging every event. But the March 17 event was the biggest impact spotted to date.
Interestingly, the lunar impact coincided with an uptick of meteor detections in the Earth’s atmosphere — a factor that has led program scientists to believe that both events stemmed from debris originating from the asteroid belt between the orbits of Mars and Jupiter. This could signify a previously unknown stream of debris that could supply more impact events in the future.
“My working hypothesis is that the two events are related, and that this constitutes a short duration cluster of material encountered by the Earth-Moon system,” said Cooke. “We’ll be keeping an eye out for signs of a repeat performance next year when the Earth-Moon system passes through the same region of space. Meanwhile, our analysis of the March 17th event continues.”
It is hoped that NASA’s Lunar Reconnaissance Orbiter (LRO) will fly over the impact site in the near future to image the fresh crater.
The rationale behind understanding the frequency of meteoroid impacts is to safeguard an extended human presence on the lunar surface. Rocks of any size traveling 56,000 mph with no atmosphere to slow them down would place spacewalking astronauts in a cosmic shooting gallery.
Since 2005, the lunar observation program has registered over 300 impact events. By identifying periods of intensified meteoroid impacts could signify that the Earth-moon system is passing through streams of interplanetary debris, similar to seasonal meteor showers. This could help mitigate the risks that moonwalkers would face in the future and may even aid lunar habitat designs.
