Smuggled sandwich

During the Gemini 3 mission, astronaut John Young secretly brought a corned beef sandwich into space . He and fellow astronaut Gus Grissom took a few bites while in orbit.

Needless to say, Mission Control wasn’t amused—there were serious concerns about crumbs floating around and interfering with the spacecraft’s systems.

Astronaut Scott Kelly pulled off a wild prank during his year in space by dressing in a gorilla suit and chasing fellow astronaut Tim Peake around the International Space Station.

The costume had been secretly sent by Scott’s twin brother, Mark Kelly, as a surprise birthday gift during the mission.

Lunar picnic

In 1969, Neil Armstrong and Buzz Aldrin made history as the first humans to walk on the Moon. But they didn’t stop there.

To mark the occasion, they also shared the first meal on the lunar surface . The menu included bacon squares, peaches, sugar cookie cubes, a pineapple-grapefruit drink, and coffee.

And unlike the smuggled corned beef sandwich incident, this meal was entirely mission-approved.

Fined by Mars "owners"

Image: Planet Volumes

In 1997, NASA was sued by three men from Yemen who claimed that Mars had been passed down to them by their ancestors.

They accused NASA of trespassing when the Pathfinder rover landed—and even began selling plots of Martian land for $2 per square meter. Of course, the case was never taken seriously.

Metric vs. Imperial

Image: Bozhin Karaivanov

Back in 1999, NASA lost a Mars orbiter due to a mix-up between metric and imperial units. One team used the metric system, while another used imperial units to track thruster force.

The error caused the spacecraft to veer off course and burn up in the Martian atmosphere. It had been intended to be the first satellite to study Mars's climate and weather in detail.

Another fine—for littering

Image: Attila Lisinszky

In 1979, NASA’s Skylab space station re-entered Earth’s atmosphere and broke apart, scattering debris across Western Australia, about 482 kilometers east of Perth.

In response, the Shire of Esperance , a local government body in Western Australia, jokingly fined NASA $400 for littering.

A building with its own weather

Image: reza shayestehpour

NASA’s Vehicle Assembly Building (VAB) at the Kennedy Space Center is one of the largest buildings in the world by volume, enclosing over 3.7 million cubic meters of space. It was originally built to assemble the massive Saturn V rockets used in the Apollo missions.

But its immense size—combined with Florida’s high humidity—once led to clouds forming inside . To prevent this, NASA installed a 10,000-ton air conditioning system to control moisture and protect delicate spacecraft.

Bathroom issues

Image: Jan Antonin Kolar

Early space missions didn’t have modern toilets—just plastic bags taped in place. During Apollo 10, this led to an awkward moment when a piece of human waste was spotted floating through the cabin .

Commander Tom Stafford asked for a napkin to grab it, but no one claimed responsibility. Minutes later, another one appeared. The crew laughed it off, but to this day, the mystery remains unsolved.

Mutiny in space

Image: Towfiqu barbhuiya

In 1974, the Skylab 4 crew spent 84 days in space—the longest mission at the time. Overworked and stressed, the astronauts staged the first space mutiny by taking a surprise day off and cutting communication with NASA.

They relaxed and enjoyed the view of Earth before resuming contact the next day. NASA wasn’t thrilled but learned a valuable lesson: space missions must care for astronauts’ mental health, not just their physical well-being.

Paid to stay in bed

Image: Kinga Howard

NASA once paid volunteers $15,000 to lie in bed for 90 days to simulate the effects of zero gravity on the human body.

It sounds like a dream job (pun intended)—until you realize they weren’t allowed to get up at all, not even for a second.

11

No insurance

Image: Vlad Deep

Before Apollo 11 launched, the crew couldn’t get life insurance due to the mission’s high risks . So Armstrong, Aldrin, and Collins came up with a clever backup plan.

They signed envelopes and postcards, which friends postmarked during the mission. If the astronauts didn’t return, their families could sell them to collectors for financial support.

The first post office? A Boston tavern

Image: Mick Haupt

In 1639, the first organized mail service in British North America started at Richard Fairbank’s tavern . The owner collected and distributed mail brought by ship.

Although informal and modest by today’s standards, this post office laid the foundation for communal mail collection and delivery.

Enter Benjamin Franklin

Image: Brett Wharton

From 1753, Franklin served as joint Postmaster General for the colonies and undertook a sweeping reform: he organized delivery routes, aligned them with major roads and rivers, and cut the mail travel time between Philadelphia and New York to about 33 hours .

He also introduced the first rate chart, standardizing delivery costs based on weight and distance, turning what had been a scattered courier network into a more reliable, structured mail system.

National Postal System founded

Image: David Trinks

With the American Revolution underway, the Second Continental Congress established the first national postal agency in 1775 , appointing Benjamin Franklin as the first Postmaster General.

This new postal service initially handled mostly military and diplomatic correspondence, but the agency laid the groundwork for what would become a national communications service.

The Age of Steam: mail by steamboat

Image: mandylin

In 1813, Congress authorized the Postmaster General to contract steamboat companies to carry mail. Soon, steamboats were ferrying mail up and down the East Coast and the Mississippi River .

By 1848, mail even traveled to California via steamship and across the Isthmus of Panama, a three-week voyage.

Overland stagecoaches and the Butterfield Overland Mail

Image: Ricky BiggsSr

Between 1858 and 1861, the Butterfield Overland Mail stagecoach service carried U.S. mail across the western frontier, from eastern posts like Memphis and St. Louis to San Francisco .

This service helped connect the eastern U.S. with rapidly growing western settlements long before the completion of the transcontinental railroad.

6

Railroads enter the picture

Image: Jay Kettle-Williams

As railroads expanded, the postal service started to use this new technology: in 1832, the first mail deliveries by train were made.

Rail transport vastly improved speed and reliability compared to horse and stagecoach travel , and became a key advance as mail traffic increased and the nation expanded westward.

7

First U.S. postage stamps

Image: The New York Public Library

In 1847, the first official U.S. postage stamps were issued: a 5-cent stamp featuring none Ben Franklin and a 10-cent stamp featuring George Washington .

Prepaid stamps simplified payment and collection of postage, removing complications from pay-on-delivery systems and helping the postal system function more efficiently.

8

The Pony Express

Image: The New York Public Library

In 1860, the Pony Express started its overland mail route between Missouri and California, nearly 1800 miles of relay horseback riding . The mail took 10 days between endpoints.

Although short-lived (it ended in 1861), the Pony Express demonstrated the demand for rapid cross-country communication.

9

City-wide home delivery

Image: Lesli Whitecotton

In 1863, free city mail delivery began , allowing residents in major cities to receive letters directly at their homes rather than picking them up at a post office.

This represented a major shift: mail became a part of everyday domestic life, not just something dropped off and picked up by hand.

10

Pneumatic tube mail in NYC

Image: The New York Public Library

In 1897, a pneumatic-tube mail system began operation in New York City. Mail could travel underground at high speeds, from the General Post Office to other offices in Manhattan within minutes .

At its peak, the system carried thousands of letters daily: at one point, nearly 30% of New York City mail went through this immense underground network.

11

Parcel post service launches

Image: Olivier Rouge

On New Year’s Day 1913, the U.S. Post Office inaugurated the first official parcel post service , allowing packages, not just letters, to be sent through the mail.

The impact was immediate: within the first five days, millions of packets passed through post offices, fueling mail-order business and expanding commerce everywhere.

12

First airmail route

Image: Qihao Wang

In 1918, the postal service launched the first regularly scheduled air mail route between Washington, D.C., and New York , marking the beginning of mail carried by airplane.

Airplane mail allowed far faster coast-to-coast and long-distance communication, a major leap from sailboats, stagecoaches, or railroads.

Contemplating the world from atop a jaw-dropping mountain view is a humbling experience everyone should go through at least once. At Angels Landing in Zion National Park, Utah, that sense of majesty is within reach.

Though stunning, this 4.8-mile hike is not to be taken lightly. It has some dangerous cliffs that make it a bit challenging. If you have vertigo, perhaps this trail is not for you. However, if you are in good shape and have an adventurous soul, the stunning scenery at the summit is something not to be missed.

Hiking isn’t just about summiting mountains—waterfalls can offer spectacular views too! This 6.8-mile loop in Pennsylvania features more than 20 waterfalls, making it one of the best waterfall hikes in the eastern United States . While some trails lead to taller, more dramatic falls, few offer the sheer number and variety found here.

Each waterfall is unique and beautiful in its own way, ranging from 15 to 50 feet in height, with the tallest reaching nearly 100 feet. But that’s not all—along this trail, you’ll also encounter fascinating rock formations and ancient old-growth forests.

11

Giant Mountain

Although New England peaks are only a third the height of the Rockies, East Coast hikes can be even more challenging due to their rugged trails, steep descents, and tricky terrain. Tackling Giant Mountain in the Adirondack High Peaks Wilderness is no small feat.

This New York trail takes 4 to 6 hours to complete, but the effort is well worth it. You’ll be rewarded with breathtaking views and a picturesque forest , making it a must-visit for those confident in their ability to take on a strenuous climb.

12

Precipice Trail

Image: Raphael Assouline

With its rocky cliffs and oceanside forests , Maine’s Acadia National Park offers a hiking experience unlike any other in the eastern United States. While all of its rugged peaks provide stunning views, no trail in Acadia is as memorable—or as challenging—as the Precipice Trail.

Despite the trail’s short length (just 2.6 miles), this is a challenging hike not recommended if you have a fear of heights. Once you reach the summit of Champlain Mountain, after nearly a thousand feet of climbing, you will be rewarded with sprawling views looking out over the park, Frenchman Bay, and the Mount Desert Narrows stretching out to the Atlantic.
