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.

15 Facts About Nicolaus Copernicus

Polish astronomer and mathematician Nicolaus Copernicus fundamentally altered our understanding of science. Born on February 19, 1473, he popularized the heliocentric theory that all planets revolve around the Sun, ushering in the Copernican Revolution. But he was also a lifelong bachelor and member of the clergy who dabbled in medicine and economics. Dive in to these 15 facts about the father of modern astronomy.

1. He came from a family of merchants and clergy.

Some historians believe that Copernicus's name derives from Koperniki, a village in Poland named after tradesmen who mined and sold copper. The astronomer's father, also named Nicolaus Copernicus, was a successful copper merchant in Krakow. His mother, Barbara Watzenrode, came from a powerful family of merchants, and her brother, Lucas Watzenrode the Younger, was an influential Bishop. Two of Copernicus's three older siblings joined the Catholic Church, one as a canon and one as a nun.

2. He was a polyglot.

Growing up, Copernicus likely knew both Polish and German. When Copernicus's father died when he was around 10, Lucas Watzenrode funded his nephew's education and he started learning Latin. In 1491, Copernicus began studying astronomy, math, philosophy, and logic at Krakow University. Five years later, he headed to modern Italy's Bologna University to study law, where he likely picked up some Italian. During his studies, he also read Greek, meaning modern historians think he knew or understood five languages.

3. He wasn't the first person to suggest heliocentrism ...

Copernicus is credited with introducing heliocentrism—the idea that the Earth orbits the sun, rather than the sun orbiting the Earth. But several ancient Greek and Islamic scholars from various cultures discussed similar ideas centuries earlier. For example, Aristarchus of Samos, a Greek astronomer who lived in the 200s BCE, theorized that Earth and other planets revolved around the Sun.

4. … but he didn't fully give credit to earlier scholars.

To be clear, Copernicus knew of the work of earlier mathematicians. In a draft of his 1543 manuscript, he even included passages acknowledging the heliocentric ideas of Aristarchus and other ancient Greek astronomers who had written previous versions of the theory. Before submitting the manuscript for publication, though, Copernicus removed this section; theories for the removal range from wanting to present the ideas as wholly his own to simply switching out a Latin quote for a "more erudite" Greek quote and incidentally removing Aristarchus. These extra pages weren't found for another 300-some years.

5. He made contributions to economics.

He's known for math and science, but Copernicus was also quite the economist. In 1517, he wrote a research paper outlining proposals for how the Polish monarch could simplify the country's multiple currencies, especially in regard to the debasement of some of those currencies. His ideas on supply and demand, inflation, and government price-fixing influenced later economic principles such as Gresham's Law (the observation that "bad money drives out good" if they exchange for the same price; for example, if a country has both a paper $1 bill and a $1 coin, the value of the metal in the coin is higher than the value of the cotton and linen in the bill, and thus the bill will be spent as currency more because of that) and the Quantity Theory of Money (the idea that the amount of money in circulation is proportional to how much goods cost).

6. He was a physician (but he didn't have a medical degree).

After studying law, Copernicus traveled to the University of Padua so he could become a medical advisor to his sick uncle, Bishop Watzenrode. Despite spending two years studying medical texts and learning anatomy, Copernicus left medical school without a doctoral degree. Nevertheless, he traveled with his uncle and treated him, as well as other members of the clergy who needed medical attention.

7. He was probably a lifelong bachelor …

As an official in the Catholic Church, Copernicus took a vow of celibacy. He never married and was most likely a virgin (more on that below), but children were not completely absent from his life: After his older sister Katharina died, he became the financial guardian of her five children, his nieces and nephews.

8. … But he may have had an affair with his housekeeper.

Copernicus took a vow of celibacy, but did he keep it? In the late 1530s, the astronomer was in his sixties when Anna Schilling, a woman in her late forties, began living with him. Schilling may have been related to Copernicus—some historians think he was her great uncle—and she worked as his housekeeper for two years. For unknown reasons, the bishop he worked under admonished Copernicus twice for having Schilling live with him, even telling the astronomer to fire her and writing to other church officials about the matter.

9. He attended four universities before earning a degree.

Copernicus spent over a decade studying at universities across Poland and Italy, but he usually left before he got his degree. Why skip the diplomas? Some historians argue that at the time, it was not unusual for students to leave a university without earning a degree. Moreover, Copernicus didn't need a degree to practice medicine or law, to work as a member of the Catholic Church, or even to take graduate or higher level courses. 

But right before returning to Poland he received a doctorate in canon law from the University of Ferrara. According to Copernicus scholar Edward Rosen this wasn't exactly for scholarly purposes, but that to "show that he had not frittered his time away on wine, women, and song, he had to bring home a diploma. That cost much less in Ferrara than in the other Italian universities where he studied."

10. He was cautious about publicizing his views.

During Copernicus's lifetime, nearly everyone believed in geocentrism—the view that the Earth lies at the center of the universe. Despite that, in the 1510s Copernicus wrote Commentariolus, or "the Little Commentary," a short text that discussed heliocentrism and was circulated amongst his friends. It was soon found circulating further afield, and it's said that Pope Clement VII heard a talk about the new theory and reacted favorably. Later, Cardinal Nicholas Schönberg wrote a letter of encouragement to Copernicus, but Copernicus still hesitated in publishing the full version. Some historians propose that Copernicus was worried about ridicule from the scientific community due to not being able to work out all of the issues heliocentrism created. Others propose that with the rise of the Reformation, the Catholic Church was increasingly cracking down on dissent and Copernicus feared persecution. Either way, he didn't make his complete work public until 1543.

11. He published his work on his deathbed.

Copernicus finishing writing his book explaining heliocentrism, De Revolutionibus Orbium Coelestium (On the Revolutions of Celestial Orbs), in the 1530s. When he was on his deathbed in 1543, he finally decided to publish his controversial work. According to lore, the astronomer awoke from a coma to read pages from his just-printed book shortly before passing away.

12. Galileo was punished for agreeing with Copernicus.

Copernicus dedicated his book to the Pope, but the Catholic Church repudiated it decades after it was published, placing it on the Index of Prohibited Books—pending revision—in 1616. A few years later, the Church ended the ban after editing the text to present Copernicus's views as wholly hypothetical. In 1633, 90 years after Copernicus's death, the Church convicted astronomer Galileo Galilei of "strong suspicion of heresy" for espousing Copernicus's theory of heliocentrism. After a day in prison, Galileo spent the rest of his life under house arrest.

13. There's a chemical element named after him.

Take a look at the periodic table of elements, and you might notice one with the symbol Cn. Called Copernicium, this element with atomic number 112 was named to honor the astronomer in 2010. The element is highly radioactive, with the most stable isotope having a half life of around 30 seconds.

14. Archaeologists finally discovered his remains in 2008.

Although Copernicus died in 1543 and was buried somewhere under the cathedral where he worked, archaeologists weren't sure of the exact location of his grave. They performed excavations in and around Frombork Cathedral, finally hitting pay dirt in 2005 by finding part of a skull and skeleton under the church's marble floor, near an altar. It took three years to complete forensic facial reconstruction and compare DNA from the astronomer's skeleton with hair from one of his books, but archeologists were able to confirm that they had found his skeleton. Members of the Polish clergy buried Copernicus for a second time at Frombork in 2010.

15. THERE ARE MONUMENTS TO HIM AROUND THE WORLD.

A prominent statue of the astronomer, simply called the Nicolaus Copernicus Monument, stands near the Polish Academy of Sciences in Warsaw, Poland. There are also replicas of this monument outside Chicago's Adler Planetarium and Montreal's Planétarium Rio Tinto Alcan. Besides monuments, Copernicus also has a museum and research laboratory—Warsaw's Copernicus Science Centre—dedicated to him.

11 Spectacular Facts About the Moon

The Moon is Earth’s closest satellite in our solar system, but in many ways, we hardly know our neighbor. Scientists aren’t entirely sure how it formed, and other facts, like its shape (more egg-like than spherical), and the consistency of its surface (dusty but firm), were confirmed only recently. With the 50th anniversary of the Apollo 11 Moon landing this year, and NASA preparing to return to the lunar surface for the first time in decades, it’s time to brush up on these facts about the Moon—from colorful names for full moons to the first landing on the dark side of the Moon.

1. The Moon may have formed when a giant object in the solar system hit Earth.

Scientists aren't in total agreement on how the Moon formed, but the most widely accepted theory is the giant impact hypothesis. According to this theory, an object the size of Mars called Theia collided with Earth 4.5 billion years ago when the solar system was still new and chaotic. The impact dislodged matter from Earth’s crust, and the debris attached to whatever was left of Theia through the force of gravity.

This scenario would explain why the Moon is made up of lighter elements found in Earth’s outer layer, but it still leaves some questions unanswered. If the giant impact hypothesis is correct, about 60 percent of the Moon should consist of the impact object. Instead, its composition is almost identical to that of Earth. There are alternative explanations: one posits that the Moon is a space object that got caught in Earth’s orbit, and another one suggests the Moon and Earth formed at the same time, but none is as popular as the giant impact theory.

2. The Moon is the perfect size for solar eclipses.

A lucky set of circumstances make total solar eclipses, as seen from Earth, possible. The Moon is just the right size and distance from our planet to appear as the same size as the Sun in the sky. When the Moon passes between the Sun and the Earth, it covers the Sun perfectly with an impressive corona illuminating its edges. If it were any smaller or farther from Earth, it would look like a blot on the Sun during a solar eclipse.

3. A full Moon has different nicknames in different seasons.

A full moon can have many colorful names, but they don’t always describe a special celestial phenomenon. Some are used to refer to a full moon that appears during a certain time of year. A harvest moon, which is the full moon closest to the autumn equinox, is the best-known example, but there are many others, including a wolf moon (first full moon of January), strawberry moon (June), and sturgeon moon (August).

4. It’s the largest moon in the solar system relative to its planet.

Our Moon isn’t the largest in the solar system (that distinction goes to Ganymede, one of Jupiter’s 79 moons), but it is the biggest in relation to the planet it orbits. With a diameter of 2159 miles and a surface area of 14.6 million square miles, the Moon is a little more than one-fourth the size of Earth. The dwarf planet Pluto has an even smaller moon-to-planet ratio. Pluto’s largest moon Charon is nearly the size of its host body, leading some astronomers to refer to the pair as a double-dwarf planet.

5. The Moon is shaped like a lemon.

The Moon may look perfectly round in the night sky, but it’s actually more of an oval shape. It came out wonky billions of years ago when super-hot tidal forces shaped its crust, heating up some areas hotter than others to form a lemon shape rather than a perfect sphere. Gravitational forces from Earth have helped to exaggerate the Moon’s oblong appearance over eons.

6. Scientists thought Moon dust would cause lunar landers to sink.

When preparing to send missions to the Moon, some scientists feared that a thick layer of dust on the body’s surface would cause complications. One of the strongest proponents of the dust theory was Thomas Gold, an astrophysicist at Cornell University. He insisted that the Moon was covered in seas of dust soft and thick enough to swallow a lunar lander. Though the Moon’s surface is dusty, the layer is too thin to cause problems, as the successful landings of the Soviet Luna 9 and the American Surveyor spacecrafts proved in 1966.

7. The Moon is international property.

Astronauts Buzz Aldrin and Neil Armstrong may have planted an American flag on the Moon in 1969, but it belongs to the world. Countries like the Soviet Union and the U.S. made sure of that at the height of the space race in 1967 when they signed the Outer Space Treaty, a document declaring that the Moon would be a “global commons” and any resources discovered there would be used for the good of the world overall. In keeping with the spirit of the agreement, NASA shared soil samples taken from the Moon with Soviet scientists upon the Apollo 11 mission's return.

8. Humans have left strange things on the Moon.

Since the first people landed on the Moon in 1969, its surface has been home to more than just dust. Earth artifacts left on the Moon by astronauts include two golf balls, an obscene Andy Warhol doodle, and a message from Queen Elizabeth II. Eugene Cernan, Apollo 17 commander and one of the last people to walk on the Moon, traced his daughter’s initials into the soil when he visited in 1972. Without any wind or weather on the Moon, the letters TDC could remain there forever.

9. The "dark side of the Moon" is the result of synchronous rotation.

Even though the Moon is constantly rotating, only one side of it is visible from Earth. This is because the Moon is locked in synchronous rotation. It takes the Moon just as long to complete one full rotation as it does for the body to orbit around the Earth once, so the same side always faces our planet. This isn’t a coincidence—the Earth’s gravitational forces have gradually pulled the tip of the slightly oblong Moon to point toward the planet, creating something called tidal lock.

In January 2019, the Chinese space agency landed the first lunar probe on the unexplored dark side of the Moon. The Chang'e 4 spacecraft sent the first photographs of a massive impact crater on the dark side to Earth, giving scientists their first glimpse of that unknown region.

10. One astronaut was allergic to the Moon.

Apollo 17 astronaut Harrison “Jack” Schmitt discovered the hard way that some people are allergic to Moon matter. Following a survey of a valley in the Sea of Serenity, he climbed back into the crew’s lunar module and tracked in a lot of Moon dust with him. The dust affected him as soon as he removed his spacesuit, triggering red eyes, sneezing fits, and other symptoms that lasted two hours.

11. Humans are going back to the Moon soon.

After completing several manned missions to the Moon, NASA ended the Apollo program in 1972 as budgets tightened and public interest waned. That means most people alive today have never witnessed a manned lunar landing, but now, following a hiatus nearing 50 years, NASA is finally preparing to return to the Moon. The next manned lunar expedition will be ready to launch “no later than the late 2020s,” according to the space agency. One of the goals will be placing a command module, called Gateway, in the Moon’s orbit that astronauts can reuse over multiple missions.
