The Apollo Astronaut Who Was Allergic to the Moon

The inside of Apollo 17’s lunar module smelled of gunpowder. It was December 1972, the last of NASA’s manned moon missions, and astronauts Eugene Cernan and Harrison “Jack” Schmitt had just finished a successful survey of the Valley of Taurus-Littrow, a spot on the southeastern “coast” of the Moon’s Sea of Serenity. They had returned to the landing module with their spacesuits caked in moondust.

The men brushed themselves off and removed their helmets. Suddenly, Schmitt began having a sneezing fit. His eyes reddened. His throat itched. His sinuses clogged.

“I didn’t know I had lunar dust hay fever,” Schmitt said. Listening in, men stationed back on Earth began to bust Schmitt’s chops over the radio transmission. “It’s funny they don’t check for that,” said Joseph Allen at Mission Control. “Maybe that’s the trouble with the cheap noses, Jack.”

Schmitt, it turns out, was basically allergic to the Moon.

Of all the difficulties involved with putting a man on the Moon, “the major issue the Apollo astronauts pointed out was dust, dust, dust,” Larry Taylor, director of the Planetary Geosciences Institute, said in an interview with the Soil Science Society of America. The Apollo 11 astronauts griped that the “particles covered everything and a stain remained even after our best attempts to brush it off.” An Apollo 12 crew member moaned that the lunar module “had so much dust that when I took my helmet off, I was almost blinded.”

Moondust may look soft and pillowy, but it’s actually sharp and abrasive, largely the detritus of micrometeorite impacts. With no wind or moving water on the Moon’s surface, moondust never erodes. Effectively, no natural process exists on the lunar surface that can round its edges. When astronauts inhale what is essentially finely powdered glass, it becomes a huge health hazard [PDF]: The powder is so jagged that a deep breath could cause it to lodge in the lungs and pierce the alveolar sacs and ducts [PDF], resulting in a lunar version of “stone-grinder’s disease,” or silicosis, a deadly condition that commonly killed coal miners (and still kills 100 Americans a year). To complicate matters, lunar dust also contains a lot of iron—and this iron-laden dust has recently been implicated in hypertension among Apollo astronauts [PDF].

Reports of moondust misadventures from previous Apollo missions never deterred Harrison Schmitt. After all, the Harvard-educated geologist had dedicated the better part of a decade to studying the Moon’s landscape. Working for the U.S. Geological Survey’s astrogeology department, he used telescope photos to map the Moon and planets. So when the NASA asked if any scientists were interested in visiting space, Schmitt hardly hesitated. “I thought about 10 seconds and raised my hand and volunteered,” he said in a 1999 oral history project with NASA.

No astronaut knew more about lunar geology than Schmitt. Previously, every other Apollo flyboy had had a background as a military pilot. Schmitt was the first, and only, professional scientist to walk on the Moon. As a result, the press didn’t romanticize or hype the geologist astronaut. The New York Times described the 37-year-old as a “quiet, serious bachelor who does not own a television set or a stereo.” As he trained to go to the Moon, completing a 53-week flight training course and logging 2100 hours of flying time, the scientist never imagined that he would wind up being allergic to the lunar dust and rocks he had spent years studying from afar.

In December 1972, Schmitt landed in the Moon’s Valley of Taurus-Littrow, surrounded by mountains and endless stretches of moondust. During their first moonwalk, the lunar roving vehicle lost a fender. The tires spun, and the rover kicked up a cloud of dust.

The sediment got lodged in every wrinkle, fold, nook, and cranny of Schmitt’s spacesuit. The dust “gummed up the joints” of his suit so badly that he had trouble moving his arms. The powder chewed up his footwear, too. “The dust was so abrasive that it actually wore through three layers of Kevlar-like material on Jack’s boot,” Taylor said.

When the astronauts returned to the lunar module, it took forever to brush the dust off. Schmitt later complained [PDF] of “a lot of irritation to my sinuses and nostrils soon after taking the helmet off ... the dust really bothered my eyes and throat. I was tasting it and eating it.” The symptoms lasted for about two hours. His condition was consistent with the findings of Dr. Bill Carpentier, a NASA doctor who had evidence suggesting the dust could cause allergic responses [PDF].

Schmitt's pesky moon allergies couldn't stop his true grit. Thanks to his background as a geologist, Apollo 17 collected more rock samples than any other mission. One sample, the 4.2-billion-year-old hunk of rubble called “Troctolite 76535,” later helped unlock secrets of the Moon’s magnetic field [PDF].

Schmitt also discovered bright orange beads of volcanic glass on the Moon’s surface. Not only did these samples prove that the Moon was once volcanically active, they also provided evidence that it contained water. And before they packed for home, Schmitt and his fellow Apollo 17 astronauts snapped a photo of Earth. Today, it’s one of the most iconic photographs of our home: the Blue Marble.

This Amateur Rocketeer Builds Functioning, Miniature Replicas of SpaceX Rockets

Amateur rocketry is a hobby that predates NASA. Hobbyists have successfully made it to space using rockets built without the massive budgets and resources available to larger organizations. And some of these rockets do more than reach incredible heights: As Motherboard reports, Joe Barnard, a 25-year-old rocketeer from Nashville, Tennessee, is working on making model rockets capable of propulsive landings, the same trick that makes some SpaceX rockets reusable.

Most rocket boosters that propel loads past the Earth's atmosphere are designed to go only one way. In 2015, Elon Musk's space exploration company SpaceX made history when it successfully maneuvered the boosters used to launch its Falcon 9 rocket back onto the landing pad. SpaceX says its latest version of the rocket can be re-flown up to 100 times, saving the company millions of dollars per launch.

Joe Barnard is bringing this same level of innovation to the amateur rocketry world. He first became interested in aerospace engineering after watching early SpaceX videos, and instead of earning a degree in the field, he taught himself the basics. He's since made rocketry into a career, founding Barnard Propulsion Systems (BPS), a small business that sells supplies to other hobbyists, and working on rockets of his own.

Like the rockets at SpaceX, Barnard's creations use thrust vectoring—the technology that makes it possible to navigate and stabilize a rocket after launch—only on a much smaller scale. He's built miniature models of SpaceX's Falcon 9 rockets, and as is the case at SpaceX, his launches don't always run smoothly.

Barnard is still perfecting propulsive landings in amateur rockets, but for now he says each failure is a learning experience. You can watch the progress of his experiments on his YouTube channel.

Ad Astra: The Time Earth Almost Got a Space Billboard

In the 1980s and well into the 1990s, everything associated with Arnold Schwarzenegger was big. Big biceps (22 inches during his bodybuilding heyday). Big box office (1991's Terminator 2: Judgment Day made $520 million worldwide, the highest-grossing movie of that year). So it was no surprise to open a newspaper in 1993 and see that Columbia Pictures was spending $500,000 to plaster the actor's name and the title of his pending summer blockbuster, Last Action Hero, on the fuselage of a NASA rocket set for launch that June. Schwarzenegger himself was scheduled to push the button that would propel the spacecraft into orbit.

The NASA project deal was being brokered for commercial advertising purposes by Space Marketing Inc., an Atlanta-based firm specializing in sponsorships and ads located outside of the atmosphere. The company's CEO, Mike Lawson, told the Los Angeles Times that he could've sold "dozens" of ads for the rocket, but that he and NASA officials didn't want it to "look like a pace car at the Indy 500."

The idea of promoting a movie in space was brazen, but not nearly as much as another, more ambitious project that Lawson was planning. If everything went according to plan, his Space Marketing would shoot a payload into space in time for the 1996 Summer Olympic Games in Atlanta. Once it was in orbit, mylar tubes would inflate with gas and spring open to support a mile-wide, quarter-mile tall reflective sheet that would be visible from Earth. Lawson called it an "inflatable platform," but the press—and critics—quickly labeled it something else: a space billboard.

If Lawson had his way, it would be able to make everything from the Olympic rings to the McDonald's logo as visible to Earthbound consumers as a full moon.

 

In Robert Heinlein's 1950 novella The Man Who Sold the Moon, a lunar entrepreneur hustles to sell advertising space on the moon as part of his attempt to make colonization a profitable venture. Lawson—a onetime director of marketing for his father's publishing company in Atlanta and a fan of science fiction—read the story. In 1988, he founded Space Marketing as a way to defictionalize the concept.

As fantastic as it sounded, the idea wasn't without precedent. In 1981, telecommunications mogul Robert Lorsch made a presentation to Congress that outlined a strategy for allowing corporations to "sponsor" space travel by letting them buy plaques that would go onboard spacecraft. In the same way they endorsed the Olympics, Lorsch said, corporate America could help subsidize space travel.

The plan was a response to then-president Ronald Reagan's plea to have the private sector assist in helping the government overcome their financial burdens. While Lorsch's proposal was prescient—it anticipated the rise of privatized space exploration—the idea of having commercial sponsors for NASA didn't make it through the Byzantine maze of Washington bureaucracy.

Lawson thought the idea could be taken further, and not necessarily with the cooperation of government. Partnering with scientists at the Lawrence Livermore National Library and the University of Colorado, Lawson developed a plan to allow instruments developed by these institutions to go into orbit and collect information about the ozone layer. To underwrite the project, he would solicit commercial advertisers for the mile-long mylar sheet that would exit the atmosphere rolled up and then expand to full size once it reached orbit. The aluminized lettering would reflect the sun's rays, making whatever graphic it displayed visible for 10 minutes at a time at any given point on Earth. After roughly 20 days, it would disintegrate, leaving the sensors behind to continue collecting data for researchers.

'We could actually fly [the] Golden Arches in space," Lawson said in May 1993, referring to the ubiquitous McDonald's logo. With an estimated launch cost of $15 to $30 million, companies buying ads would cover expenses as well as contribute to a profit for Space Marketing—perhaps paying as much as $1 million for every day it was visible.

A few months later, the city of Atlanta began investigating Space Marketing's concept as a possible advertising vessel for the 1996 Olympics. "Special" glasses given away at point-of-purchase displays with cooperating sponsors would allow people to see the Olympic rings in orbit.

That last point appeared to be a concession to a growing chorus of concern over the idea of using space as a commercial entity. While proponents of the idea argued it was similar to blimps sailing overhead and displaying corporate propaganda messages, a coalition of scientists argued otherwise. Carl Sagan called it an "abomination," insisting that astronomy could soon become a practice of exploring the stars wedged between mile-wide ads for fast food and automobiles.

Consumer advocate Ralph Nader led a group calling for an orbital billboard ban, labeling it a practice of "defacing the heavens." Other groups decried it as commercial pollution of space and vowed to boycott any companies involved. Supporters of Nader's Public Interest Research Group picketed Space Marketing's Atlanta headquarters.

Lawson tried to parry the attacks in media, saying that the phrase "space billboard" was the source of the controversy. He preferred the term "environmental billboard" and said that the whole objective was to have a global company foot the bill for scientific research.

 

Conceptually, the idea of a floating Arby's logo the perceived size of the moon was too dystopian for lawmakers to handle. In 1993, Congress submitted legislation that would prohibit the Transportation Department from issuing a launch license to any company prepared to shoot a corporate image into space. (The bill was eventually signed into law by Bill Clinton in 2000.)

None of this publicity was particularly helpful to Space Marketing, which saw its Olympic plans wilt in the face of both legislative opposition and the probability of massive pushback from space advocacy groups. They turned their attention to Russia, which had no ethical objections to space endorsements, and facilitated a 1999 project that saw Pizza Hut attach its logo to the Proton rocket that carried supplies to the International Space Station. (The chain previously considered projecting its logo with lasers on the surface of the moon but abandoned the idea when they realized it would cost hundreds of millions of dollars.)

Space Marketing's investors moved on to the blimp industry and the firm was dissolved by 2007, when Lawson became CEO of airship manufacturer Techsphere Systems. As for the Last Action Hero stunt: It dissolved when Columbia learned Lorsch was threatening legal action, claiming he owned a copyright on the idea of commercial space advertising. The movie itself also failed to launch, becoming a notorious summer bomb when it was pitted against Jurassic Park.

While space has largely been off-limits to such "obtrusive" advertising by law, not everyone agrees that's for the best. Earlier this month, it was reported that NASA is looking into selling off the naming right to its shuttles as a way to recoup some of the organization's costs. When Lorsch testified before a Senate subcommittee in 2004 to review his 1981 proposal, he said that his sponsorship program might have earned NASA $5 billion in revenue if it had been implemented.
