"One small step" vs. "Man, that may have been a small one…"

Neil Armstrong stepped onto the lunar surface with his carefully planned line: "That is one small step for a man , one giant leap for mankind." Pete Conrad from Apollo 12 decided to have some fun with that.

Conrad was short, and he had bet a reporter five hundred dollars that he could say whatever he wanted when he stepped down. This is the line he went for, as documented in NASA transcripts: "Whoopie! Man, that may have been a small one for Neil, but that is a long one for me ."

Apollo 12 and the lightning strike that tried to end everything

Apollo 12 was struck by lightning not once but twice, only 36 seconds after launch. The electrical surge wiped out telemetry in Mission Control.

The flight looked doomed until flight controller John Aaron said the now legendary instruction: "Try SCE to Aux." Conrad responded with, "What the hell is that?" because almost no one remembered what SCE meant.

Luckily, Alan Bean understood what to do. He flipped the switch, the instruments rebooted, and Apollo 12 kept flying.

Apollo 13 was just as dramatic as the movie showed

The explosion of an oxygen tank in Apollo 13’s service module really did turn the mission into a race against time. The line "Houston, we have a problem" is Hollywood’s adaptation, however. The real line, spoken by Jack Swigert and repeated by Jim Lovell, was "Houston, we have had a problem."

Other real drama: the crew used the Lunar Module as a lifeboat, battled rising CO₂ levels, manually aligned the spacecraft using Earth’s horizon, and returned home with only a sliver of battery life left.

Apollo 16 astronauts drove a moon rover like teenagers with a new car

The lunar rover was a marvel: lightweight, foldable, and capable of reaching 13 to 18 km/h depending on conditions.

John Young and Charlie Duke from Apollo 16 were so thrilled with it that Mission Control had to repeatedly remind them not to drive too fast on uneven terrain.

Duke even recorded one of the wildest moments of the program when Young yelled, "Look at that… look at that!" as dust flew up behind them.

The dust that drove astronauts nuts

Moon dust is sharp, sticky, and electrostatically clingy. Astronauts from Apollo 11 onward complained that it smelled like burnt gunpowder and got everywhere. Harrison Schmitt from Apollo 17 suffered "lunar hay fever" after breathing dust tracked into the cabin.

NASA later became mildly obsessed with studying how dangerous that dust might be… and it turns out it is genuinely abrasive to suits and could be risky to lungs.

Apollo 11 and the computer that said "nope"

Just minutes before landing on July 20, 1969, the Apollo Guidance Computer flashed a "1202" program alarm. In non-NASA terms, the computer was overloaded and essentially panicking .

But guidance officer Steve Bales had trained for this exact situation and cleared the crew to proceed. Armstrong later said this call was one of the mission’s most decisive moments. So yes, the first Moon landing almost got canceled by a stressed-out computer.

The golf shot that echoed through history

On Apollo 14, Alan Shepard smuggled a makeshift golf club head along with two golf balls.

On the moon, he attached it to a sample collection tool and made the most famous swing in the Solar System. The ball truly did travel far, although probably not the "miles and miles" Shepard joked about. Still, it remains the only round of lunar golf ever played.

8

Apollo 15’s postal controversy

The Apollo 15 astronauts carried unauthorized stamped envelopes to sell to collectors later.

This became a scandal when the deal came to light. NASA was furious, the crew was reprimanded, and the agency tightened rules on what astronauts could take to space.

The event is fully documented and remains one of the strangest side stories of the program.

Twelve people walked on the moon

Between 1969 and 1972, exactly twelve astronauts walked on the lunar surface.

The list, in chronological order, is: Armstrong, Aldrin (Apollo 11), Conrad, Bean (Apollo 12), Shepard, Mitchell (Apollo 14), Scott, Irwin (Apollo 15), Young, Duke (Apollo 16), and Cernan and Schmitt (Apollo 17). Cernan remains the last human to have walked on the Moon.

10

The last moonwalk included a love letter

During Apollo 17, Gene Cernan traced his daughter’s initials TDC on the lunar dust.

As he said his farewell words on the Moon, he hoped the world would continue exploring. His last line: "We leave as we came and, God willing, as we shall return, with peace and hope for all mankind."

National Mall’s hidden tunnel (Washington, DC)

The National Mall landscape in Washington, DC, is so familiar that it’s hard to imagine anything hidden beneath it, but there is more going on below the surface than most visitors realize.

Beneath parts of the Mall, a network of underground tunnels connects buildings like the Smithsonian Institution Building, a.k.a "The Castle", with other Smithsonian facilities, including the National Museum of Natural History. They’re mainly used for utilities, secure staff access, and behind-the-scenes operations that keep the museums running smoothly.

2

Mount Rushmore’s secret chamber (Keystone, SD)

When you look at Mount Rushmore, the first thing you notice is the four faces of George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln, but there’s more than meets the eye. Hidden behind Lincoln’s head is a secret chamber known as the "Hall of Records," a place visitors have rarely ever seen. It was the idea of sculptor Gutzon Borglum, who imagined it as a grand room to hold important US documents and tell our story as a country. Construction began with that goal, but the project was never completed. Today, the chamber remains unfinished, but it's there, waiting to be visited someday.

The Las Vegas sign is in another city (technically, Paradise, NV)

Do you have the classic picture in front of the iconic "Welcome to Fabulous Las Vegas" sign? If you snapped it and then drove to another city, we hate to break it to you, but you weren’t in Las Vegas.

The famous sign, installed in 1959, actually sits a couple of miles outside the city limits. In fact, the sign and most of the Strip are technically located in the towns of Paradise and Winchester, unincorporated communities in Clark County, Nevada, not within Las Vegas itself. And that’s no accident: much of the Strip and its casinos were originally developed outside the city in the 1950s to avoid municipal taxes and regulations.

Fragments of the Antarctic ice sheets (Denver, CO)

Did you know that the Mile High City stores miles of ice from Greenland and Antarctica? Ok, but how?

At Denver’s National Ice Core Laboratory, part of the Federal Science Center, the ice is kept at around -32.8°F. Researchers study it not just to understand Antarctica itself, but also to inspect Earth’s history. Some of these blocks of ice are hundreds of thousands of years old, and from them, scientists can reconstruct ancient temperatures, track greenhouse gas levels, and even identify major volcanic eruptions preserved in the layers.

The hatch at the top of City Hall Tower (Philadelphia, PA)

Counting the statue of William Penn at its summit, the tower of Philadelphia City Hall rises about 548 feet, making it the tallest municipal building in the United States. But hidden high above the street, the statue conceals a little-known secret.

At its base is a small hatch, originally built to give workers access for maintenance. It offers an incredible vantage point over the city, but getting there isn’t easy. To reach it, you have to climb narrow stairways and walk through tight, elevated passageways. Would you dare give it a try?

A 112,544 square-foot underground bunker (White Sulphur Springs, WV)

The tense atmosphere and threats of the Cold War led to the construction of thousands of underground bunkers across the US. And one of the most impressive is right beneath the Greenbrier Resort in White Sulphur Springs, West Virginia.

Buried 720 feet into the hillside, this 112,544-square-foot bunker was created to shelter all 535 members of the US Congress in the event of a nuclear attack. Built between 1958 and 1961, it was sealed behind a 25-ton blast door, and it remained a protected secret for more than 30 years.

Catacombs underneath City Market (Indianapolis, IN)

In downtown Indianapolis, the City Market has been a gathering place since 1886, filled with local vendors, cafés, and shops. But there’s more to it than what you see above ground. Beneath the market lies a network known as the City Market’s "catacombs."

Despite the name, the reality isn't quite so macabre; they’re a series of brick archways that once supported Tomlinson Hall, a huge market building demolished in the mid-20th century. Today, this underground space remains as a hidden piece of the city’s past, but unlike many places on this list, it’s occasionally open for guided tours.

One of history's biggest art heists (Boston, MA)

We all know Boston as the "birthplace of the American Revolution," home to events like the Boston Massacre and the Boston Tea Party. But there’s another chapter of its history you don’t hear about as often.

Just over 30 years ago, Boston was the scene of one of the biggest art heists in history. In the early hours of March 18, 1990, two men disguised as police officers entered the Isabella Stewart Gardner Museum, overpowered the guards, and stole 13 invaluable works of art, including pieces by Vermeer, Degas, Rembrandt, and Manet. To this day, the case remains unsolved, and a multi-million-dollar reward is still offered for information.

One of the quietest places on Earth (Minneapolis, MN)

Where do you think the quietest places on Earth are? You might imagine remote landscapes far from civilization, but one of them is actually right in Minneapolis, Minnesota.

Inside Orfield Laboratories, there’s a room with no windows or natural light, an anechoic chamber that absorbs nearly all sound. That’s right: it blocks almost every noise, making the space even quieter than a vacuum. Visitors say the silence is so intense that you can hear your own heartbeat and even the faintest movements of your body. Simply incredible.

10

A strange law (Los Angeles, CA)

Why would a city actually pass an ordinance saying that licking toads is a bad idea? That’s Los Angeles, a place full of quirks, some charming, some downright strange. Even its laws can be unusual.

The Colorado River toad, found in parts of California, secretes chemicals that can have powerful psychoactive effects on humans. Because of the risks, both possession and use of this substance are illegal statewide. In 1994, cases occurred, including a teacher who was arrested for possessing the toad substance. But Los Angeles went a step further, passing an ordinance that specifically bans licking these amphibians. And let’s be honest, the poor toad probably doesn’t enjoy it either.

Frozen dead guy days

If you think your family has odd traditions, wait until you hear about Frozen Dead Guy Days in Estes Park, Colorado.

This festival is inspired by the real-life story of Bredo Morstoel, a Norwegian man who was cryogenically frozen in a shed in Colorado (yes, really.) After local officials discovered the situation, instead of shutting it down, they embraced it and turned it into a full-blown festival.

Now, every March, thousands of visitors gather to watch coffin races, polar plunges, and even a Frostbite Fashion Show. A festival to die for, huh?

Ever thought of carrying your spouse through an obstacle course? In Newry, Maine, that’s exactly what happens every October at the North American Wife Carrying Championship.

Let us explain: Teams race across a 278-yard course with two dry obstacles and one water challenge, all while carrying their partner upside down, legs over the shoulders.

You don’t have to be married to enter, any duo can participate. The winners get a hilarious prize: the carried person’s weight in beer and five times their weight in cash. We’re in!

Twice a year, Huntington Beach, California, becomes a fluffy paradise thanks to Corgi Beach Day. What’s not to love about these short, stubby-legged dogs? This festival is to celebrate them!

Thousands of corgis, and their humans, of course, gather on the sand to play, dress up, and compete in fun contests. There are food trucks, vendors selling corgi-themed goodies, and even giveaways. Best part? All breeds are welcome, just be sure to dress up your pup in something fun, so they stand out among the sea of short legs and wagging tails.

Underwater music festival

Music festivals are fun, but how about one underwater? Every July, divers and snorkelers in the Lower Keys, Florida, gather for the Underwater Music Festival, where music is played through special underwater speakers.

People dress as mermaids and sea creatures, pretending to play fish-shaped instruments as they float through the ocean. The festival promotes coral reef conservation, making it both entertaining and educational. The kind of fun we love!

Art Car Parade

Every April, the streets of Houston, Texas, transform into a moving art gallery. The Art Car Parade features vehicles that have been painted, sculpted, and decorated into rolling masterpieces.

Some cars look like bananas, shoes, or space-themed creations, while others resemble Mad Max-style hot rods. What started as a small event in the 1980s has grown into the biggest free event in Houston, with up to 300,000 spectators lining the streets.

Have you got a twin? Pack your bags and head to Twinsburg, Ohio. A place that lives up to its name by hosting Twins Days every August, the largest annual gathering of twins in the world.

Twins from all over attend, participating in a "Double Take! parade, contests, and research studies. Scientists and universities even conduct twin-related research, with some offering cash or gift incentives for participation. Every year, the festival has a theme, and many twins show up in matching costumes.

If you’ve ever wondered about aliens and UFOs, Roswell, New Mexico, is the place to be in July.

The UFO Festival celebrates the famous Roswell Incident of 1947 when a flying saucer crash-landed near the town. We know that the government later said it was just a high-altitude research balloon, but many people still believe aliens were involved. The festival includes parades, alien costume contests, laser shows, and an "Alien Crawl" bar event for adults. An out-of-this-world experience, if we may say so!

Bigfoot may be a Pacific Northwest legend, but in Marion, North Carolina, he’s a local celebrity. The WNC Bigfoot Festival started in 2018 after reported Bigfoot sightings in the area, and it’s been a hit ever since.

Every May, visitors travel to the town to hear Bigfoot experts give lectures, watch a Bigfoot-calling contest, and browse Sasquatch-themed art and souvenirs. Would you like to go to this one?

In Point Pleasant, West Virginia, people embrace the mystery of the Mothman, a red-eyed winged creature first spotted in 1966.

Now, every September, the Mothman Festival celebrates the legend with vendors, cryptid-themed art, Mothman-shaped food, and hayrides. Visitors can also tour the Mothman Museum or take a bus tour of the infamous TNT area, where the creature was first seen.
