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.

How the Hubble Space Telescope Helped the Fight Against Breast Cancer

The beauty of scientific research is that scientists never really know where a particular development might lead. Research on Gila monster venom has led to the invention of medication that helps manage type 2 diabetes, and enzymes discovered in the hot springs of Yellowstone National Park are now widely used for DNA replication, a technique used by forensic scientists to analyze crime scenes.

The same rule of thumb applies to NASA scientists, whose work has found dozens of applications outside of space exploration—especially in medicine.

Take the Hubble Space Telescope. Launched in 1990, the Hubble has graced us with stunning, intimate photographs of our solar system. But it wasn't always that way—when the telescope was launched, the first images beamed back to earth were awfully fuzzy. The image processing techniques NASA created to solve this problem not only sharpened Hubble's photos, but also had an unexpected benefit: Making mammograms more accurate.

As NASA reports, "When applied to mammograms, software techniques developed to increase the dynamic range and spatial resolution of Hubble's initially blurry images allowed doctors to spot smaller calcifications than they could before, leading to earlier detection and treatment."

That's because the Hubble Space Telescope contains a technology called Charge-Coupled Devices, or CCDs, which are basically electron-trapping gizmos capable of digitizing beams of light. Today, CCDs allow "doctors to analyze the tissue by stereotactic biopsy, which requires a needle rather than surgery," NASA says [PDF]. Back in 1994, NASA predicted that this advancement could reduce national health care costs by approximately $1 billion every year.

And that's just one of the tools NASA has developed that's now being used to fight breast cancer. When cancer researcher Dr. Susan Love was having trouble studying breast ducts—where breast cancer often originates—she turned to research coming out of NASA's Jet Propulsion Laboratory. As Rosalie Chan reports for the Daily Beast, the Jet Propulsion Lab has dedicated vast resources to avoiding the spread of earthly contaminants in space, and its research has included the development of a genomic sequencing technology that is "clean and able to analyze microscopic levels of biomass." As Dr. Love discovered, the same technology is a fantastic way to test for cancer-linked microorganisms in breast duct tissue.

A second technology developed at NASA's Jet Propulsion Laboratory—the Quantum Well Infrared Photodetector, or QWIP—enables humans to see invisible infrared light in a spectrum of colors, helping scientists discover caves on Mars and study volcanic emissions here on Earth. But it's also useful at the doctor's office: A QWIP medical sensor can detect tiny changes in the breast's blood flow—a sign of cancer—extremely early.

And as any doctor will tell you, that's huge: The earlier cancer is detected, the greater a person's chance of survival.

11 Things You Might Not Know About Neil Armstrong

No matter where private or government space travel may take us in the future, NASA astronaut Neil Armstrong (1930-2012) will forever have a place as the first human to ever set foot on solid ground outside of our atmosphere. Taking “one small step” onto the moon on July 20, 1969, he inspired generations of ambitious people to reach for the stars in their own lives. And ow, he's inspired a new biopic, First Man, which will see Ryan Gosling re-team with his La La Land director Damien Chazelle as it arrives in theaters this weekend.

1. HE KNEW HOW TO FLY BEFORE HE GOT A DRIVER’S LICENSE.

Born August 5, 1930 in Wapakoneta, Ohio, Armstrong became preoccupied with aviation early on. At around age 6, his father took him on a ride in a Ford Trimotor airplane, one of the most popular airplanes in the world. By age 15, he had accumulated enough flying lessons to command a cockpit, reportedly before he ever earned his driver’s license. During the Korean War, Armstrong flew 78 combat missions before moving on to the National Advisory Committee for Aeronautics (NACA), the precursor to NASA.

2. HIS FAMOUS QUOTE GETS MISINTERPRETED.

When Armstrong and Buzz Aldrin touched down on the moon, hundreds of millions of television viewers were riveted. Armstrong could be heard saying, “That’s one small step for man, one giant leap for mankind.” But that’s not exactly what he said. According to the astronaut, he was fairly sure he stated, “That’s one small step for a man, one giant leap for mankind.” The “a” may have broken up on transmission or it may have been obscured as a result of his speaking patterns. (According to First Man: The Life of Neil A. Armstrong, Armstrong said, “I’m not particularly articulate. Perhaps it was a suppressed sound that didn’t get picked up by the voice mike. As I have listened to it, it doesn’t sound like there was time for the word to be there. On the other hand, I think that reasonable people will realize that I didn’t intentionally make an inane statement, and certainly the ‘a’ was intended, because that’s the only way the statement makes any sense. So I would hope that history would grant me leeway for dropping the syllable and understand that it was certainly intended, even if it wasn’t said—although it actually might have been.”) Armstrong claimed the statement was spontaneous, but his brother and others have claimed he had written it down prior to the mission.

3. WE DON’T HAVE A REALLY GOOD PICTURE OF HIM ON THE MOON.

One of the most celebrated human achievements of the 20th century came at a time when video and still cameras were readily available—yet there are precious few images of Armstrong actually walking on the surface of the moon. (One of the most iconic shots, above, is Aldrin; Armstrong only appears as a reflection in his helmet.) The reason, according to Armstrong, is that he really didn’t care and didn’t think to ask Aldrin to snap some photos. “I don't think Buzz had any reason to take my picture, and it never occurred to me that he should,” Armstrong told his biographer, James R. Hansen. “I have always said that Buzz was the far more photogenic of the crew."

4. A DOOR HINGE MAY HAVE MADE ALL THE DIFFERENCE.

Theories abound as to why it was Armstrong and not Buzz Aldrin who first set foot on the moon. (On the Gemini missions, the co-pilot did the spacewalks, while the commander stayed in the craft. For Apollo 11, Armstrong was the commander.) The answer may have been the simple logistics of getting out of their lunar module. The exit had a right hinge that opened inwardly, with the man sitting on the left (Armstrong) having the most unobstructed path to the outside. Aldrin would have essentially had to climb over Armstrong to get out first.

5. HE WAS MORE CONCERNED ABOUT LANDING ON THE MOON THAN HE WAS WALKING ON IT.

The romantic notion of a human stepping foot on space soil captured imaginations, but for Armstrong, it was getting there in one piece that was the real accomplishment. The lunar module Armstrong controlled had to be brought down on the moon’s surface from 50,000 feet up, avoiding rocks, craters, and other obstacles as it jockeyed into a position for landing. Because there is no air resistance, nothing could slow their descent, and they used thrusters to guide the craft down. That meant there was only enough fuel to attempt it once. The “business” of getting down the ladder was, in Armstrong’s view, less significant.

6. HE WAS CARRYING A BAG WORTH $1.8 MILLION.

When Armstrong surveyed the surface of the moon, he collected a bag of dust for NASA scientists to examine. Apollo moon samples are illegal to buy or sell, but that apparently wasn't the case with the “lunar collection bag” Armstrong used to hold the samples. In 2015, the bag was purchased by Chicago resident Nancy Lee Carlson from a government auction site for $995. But its sale was, apparently, an accident: When Carlson sent the bag to NASA to confirm its authenticity, NASA said it was their property and refused to send it back—so Carlson took the agency to court. A judge ruled it belonged to Carlson, and in 2017, she sold the bag for a whopping $1.8 million at a Sotheby’s auction.

7. HE HAD TO SPEND THREE WEEKS IN QUARANTINE.

When Armstrong, Aldrin, and Michael Collins (who remained behind in the command module while the other two touched down on the moon) returned to Earth and were fetched by the USS Hornet, they got a king’s welcome. The only asterisk: They had to bask in their newfound fame from inside a sealed chamber. All three men were quarantined for three weeks in the event they had picked up any strange space virus. When President Richard Nixon visited, he greeted them through the chamber’s glass window.

8. HIS APOLLO SPACE SUIT WAS MADE BY PLAYTEX.

Yes, the undergarment people. In the early 1960s, NASA doled out contract work for their space suits to government suppliers, but it was Playtex (or more properly the International Latex Corporation) and their understanding of fabrics and seams that led to NASA awarding them responsibility for the Apollo mission suits. Their A7L suit was what Armstrong wore to insulate himself against the harsh void of space when he made his famous touchdown. The astronaut called it “reliable” and even “cuddly.”

9. HE BECAME A UNIVERSITY PROFESSOR.

Following his retirement from NASA in 1971, Armstrong was reticent to remain in the public eye. Demands for his time were everywhere, and he had little ambition to become a walking oral history of his singular achievement. Instead, he accepted a job as a professor of engineering at the University of Cincinnati and remained on the faculty for eight years.

10. HE ONCE SUED HALLMARK.

Hallmark was forced to defend itself when Armstrong took issue with the company using his name and likeness without permission for a 1994 Christmas ornament. The bulb depicted Armstrong and came with a sound chip that said phrases like, “The Eagle has landed.” The two parties came to an undisclosed but “substantial” settlement in 1995, which was, according to First Man, donated to Purdue University (minus legal fees).

11. HE ENDORSED CHRYSLERS.

Armstrong’s preference to lead a private life continued over the decades, but he did make one notable exception. For a 1979 Super Bowl commercial spot, Armstrong agreed to appear on camera endorsing Chrysler automobiles. Armstrong said he did it because he wanted the struggling U.S. car maker to improve their sales and continue contributing to the domestic economy. The ads never mentioned Armstrong was an astronaut.
