Since human flight was first possible, aerial archaeology has assisted researchers in uncovering previously unknown sites that are imperceptible from the ground. Today, thanks to advanced technology, remote sensing has moved higher above the Earth: Aerial archaeology is now sometimes space archaeology. By examining maps of the planet's surface taken from space, laptop-based Indiana Joneses can search vast areas for anomalies that could indicate evidence of the human past hidden for centuries. Below are four amazing archaeological discoveries spotted from space.

1. 3100 SETTLEMENTS, 1000 LOST TOMBS, AND 17 PYRAMIDS ACROSS EGYPT

Sarah Parcak is a space archaeologist and Egyptologist who since 2003 has discovered numerous archaeological sites across Egypt, all through her computer. Parcak specializes in analyzing satellite images taken from 400 miles overhead, processing the pictures to highlight parts of the electromagnetic spectrum the naked human eye cannot see. This allows her to note anomalies that could denote archaeological sites hidden underground.

It is highly specialized work. The tiny blips on the maps would mean nothing to the uninitiated, but to Parcak they provide clues that have led her to discover the location of 17 potential pyramids, some 3100 settlements, and 1000 lost tombs across Egypt. Parcak also used remote sensing to identify the location of the lost city of Tanis, which gained notoriety when it was featured in Raiders of the Lost Ark. The network of streets and houses of Tanis are completely invisible at ground level, and yet using infrared satellite images, Parcak was able to show the massive extent of the ancient settlement.

Parcak gave a hugely popular TED talk on space archaeology in 2012, and in 2015 was awarded the 2016 $1 million TED prize. She's used the money to create the citizen science platform GlobalXplorer, which allows anyone to analyze images from space in order to discover more lost archaeological sites across the globe—and spot evidence of looters.

2. THE FINAL DAYS OF THE MAYAN CIVILIZATION

The heavily forested Petén region of northern Guatemala is home to some of the most important Maya ruins in Central America, including Tikal. Archaeologists have been working with NASA using remote sensing to examine the Petén jungle from space in the hope of identifying lost sites associated with the Maya, whose culture reached the height of its power and influence from the 7th to the 9th centuries—and then collapsed around the turn of the 10th century.

In order to gain a greater understanding of this collapse, Tom Sever, the first archaeologist to work for NASA, has been analyzing images taken from an agency satellite program known as SERVIR which was launched from Marshall Space Flight Center in Huntsville, Alabama in 2005. Sever has used the images to further his theory—one also promoted by Jared Diamond in his popular book Collapse but not accepted by all Maya scholars—that what brought down the Maya was self-induced ecological disaster. The images indicate that the Maya used slash-and-burn agricultural practices that led to severe deforestation. They also drained the wetlands known as bajos, as evidenced by images of ancient drains, causing drought and resulting in an increase in temperature. The fate of the Maya is now often held up as a prime example of the risk of deforestation and climate change.

3. HOW AND WHERE THE EASTER ISLAND MOAI WERE MOVED

The iconic statues on Easter Island have fascinated archaeologists since they were first noted by a Dutch explorer in 1722. But the biggest mystery is how the Rapa Nui managed to transport these enormous monoliths from the quarries where they were made to numerous sites across the island without the help of large animals or cranes.

In 2012, Carl Lipo of California State University and Terry Hunt of the University of Hawaii used satellite imagery to trace the ancient path of the stones from the quarry to various points around the island, identifying seven major roads [PDF]. The discovery of these routes led Lipo and Hunt to suggest that the upright statues might have been “walked” to their destinations, using ropes to tilt and turn the monoliths into motion. To test out their theory, the National Geographic Society’s Expeditions Council funded an experiment in which a concrete 10-foot, 5-ton copy of a moai was constructed. Using strong ropes, 18 people were able to fairly easily walk the massive statue a few hundred yards.

4. THE LOST CITY OF IRAM/UBAR

Five thousand years ago, a grand city in the deserts of Oman formed the center of the valuable frankincense trade. Known as Iram or Ubar, the legendary city was mentioned in both the Koran and The Thousand and One Nights (a.k.a. The Arabian Nights). Yet no modern trace of this once great city could be found. Notable explorer T. E. Lawrence ("Lawrence of Arabia") referred to it as “the Atlantis of the sands,” and some historians began to doubt it had ever existed. The mystery of the lost city was sufficiently tantalizing to attract the notice of NASA, who agreed to scan the area with a shuttle radar system after being approached by filmmaker and explorer Nicholas Clapp.

A Challenger space mission in 1984 provided the perfect opportunity to scan the desert of Oman from space, searching for geological features hiding under the sand. The resultant pictures revealed ancient caravan routes, which would have been packed down over hundreds of years by the camel trains traveling between trade hubs, the intersections of these roads providing clues as to potential locations for a city. Using this information, archaeologists began to dig at promising locations, and in 1991 Clapp and his team uncovered a many-towered fortress (like that described in the Koran), which would have been the home of the king and hub for the storage of frankincense. This led them to believe that they had finally uncovered the lost city of Ubar.

Ancient sources claimed that the city had disappeared into the Earth after its citizens angered Allah with their lavish and sinful way of life. Evidence from the site in Oman suggests that the destruction of the city occurred due to the appearance of a giant sinkhole, explaining how this once great city was lost to the sands.

Dozens of Cat Mummies, Plus 100 Cat Statues, Discovered in 4500-Year-Old Egyptian Tomb

The mummification of cats was a common practice in ancient Egypt, but it’s always a pleasant surprise when the felines are found thousands of years later. As NPR reports, dozens of mummified cats and 100 wooden cat statues were recently discovered in a 4500-year-old tomb near Cairo.

These items were uncovered by Egyptian archaeologists while excavating a newly discovered tomb in Saqqara, whose necropolis served the ancient city of Memphis. Another nearby tomb remains sealed, and it’s possible that it may have evaded looters and remained untouched for millennia.

In addition to the wooden statues, one bronze cat statue was found. It was dedicated to Bastet, goddess of cats, who was said to be the daughter of Re, god of the Sun. While cats were revered by ancient Egyptians, they weren’t directly worshipped. Rather, gods like Bastet were often depicted with the physical characteristics of an animal that was considered divine.

Even rarer than the mummified cats were a couple collections of mummified scarab beetles that were found in the tomb—the first of their kind to be unearthed in this particular necropolis, Egypt's Ministry of Antiquities announced in a Facebook post. The scarabs were still in “very good condition” because they had been wrapped in linen and placed inside two limestone sarcophagi, whose lids had black scarabs painted on top.

"The (mummified) scarab is something really unique. It is something really a bit rare," Mostafa Waziri, secretary general of Egypt's Supreme Council of Antiquities, told Reuters and other media. "A couple of days ago, when we discovered those coffins, they were sealed coffins with drawings of scarabs. I never heard about them before."

The beetles were an important religious symbol in ancient Egypt, representing renewal and rebirth. The Ministry of Antiquities said archaeologists also found wooden statues of a lion, a cow, and a falcon, as well as painted wooden sarcophagi of cobras (with mummies inside) and wooden sarcophagi of crocodiles.

12 Doomed Facts About the S.S. Edmund Fitzgerald

The wind in the wires made a tattle-tale sound
When the wave broke over the railing
And every man knew, as the captain did too
'Twas the witch of November come stealin'
-Gordon Lightfoot, "The Wreck of the Edmund Fitzgerald" (1976) 

On November 10, 1975, two ships made their way in tandem across the stormy waters of Lake Superior. One was the Arthur M. Anderson, led by Captain Jesse Cooper. The other, captained by Ernest McSorley, was the S.S. Edmund Fitzgerald.

The ship was last seen on radar around 7:15 p.m. All 29 men on board were lost with it, and today, more than four decades after the most famous shipwreck in Great Lakes history, the cause is still a mystery.

Here's what we do know about the S.S. Edmund Fitzgerald, and what happened to it that fateful day:

1. IT WAS THE LARGEST SHIP ON THE GREAT LAKES.

The large cargo vessels that roamed the five Great Lakes were known as lakers, and the S.S. Edmund Fitzgerald was, at the time, the biggest ever built. It was constructed as a “maximum sized” bulk carrier and spanned 729 feet—the first laker to reach that length—sat 39 feet high with a width of 75 feet, and weighed more than 13,000 tons without cargo. It was christened on June 8, 1958, and made its first voyage on September 24 the same year. 

2. THE SHIP WAS OWNED BY AN INSURANCE COMPANY.

Great Lakes Engineering Works of Ecorse, Michigan, was contracted to build the ship in 1957 by Northwestern Mutual Insurance Company, which had invested heavily in the iron and minerals industries. With the commissioning of the Fitzgerald, Northwestern Mutual became the first American insurance company to build its own ship—at a cost of $8.4 million, the most expensive price tag for a freighter at the time, according to Michael Schumacher’s The Mighty Fitz.

3. IT WAS NAMED AFTER THE HEAD OF THE COMPANY.

The chairman of Northwestern Mutual had a long history with the Great Lakes shipping industry. Edmund Fitzgerald’s grandfather captained a ship on the lakes, his father owned a shipyard, and they both had ships named after them. After construction of the Fitzgerald was complete, Northwestern Mutual placed its charter with the Columbia Transportation Division of Oglebay Norton Company, based in Cleveland. 

4. THE SHIP'S MAIN JOB WAS HAULING IRON ORE.

Most lakers traversing the Great Lakes and the connecting waterways carry massive amounts of raw materials such as rock, salt, and grain. The Edmund Fitzgerald generally loaded taconite, low-grade iron ore, from mines on the shores of Minnesota and transported the pellets to steel mills near Detroit and Toledo, Ohio.

5. "THE FITZ" WAS WELL-KNOWN EVEN BEFORE IT SANK.

Its impressive size made the ship popular with boat-watchers, and over the years it garnered many nicknames, including “The Queen of the Great Lakes,” “The Toledo Express,” and the unfortunate “Titanic of the Great Lakes.” Crowds would watch as the massive freighter moved through the locks at Sault Ste. Marie in Michigan’s Upper Peninsula. The “Soo” Locks, which connect Lake Superior to Lake Huron, allowed the Fitz to reach ports on the lower Great Lakes.

6. THE SHIP RAN INTO A DEADLY STORM ON LAKE SUPERIOR.

November is a brutal month on the Great Lakes. Frequent storms and hurricane-force winds can batter even the toughest-built freighters. On November 9, the Fitz was loaded with 26,116 tons of iron ore pellets at the Burlington Northern Railroad Dock in Superior, Wisconsin. It left at 2:30 p.m. A second ship, the Arthur M. Anderson, sailed 10-15 miles behind the Fitzgerald as a precaution, and the two ships remained in radio contact until just after 7 p.m. on November 10.

Gale warnings had been issued by the National Weather Service the previous day, and by the morning of the 10th, the advisories had been upgraded to an official storm warning. 

As swells reached 35 feet and winds raged at nearly 100 mph, the ship contacted Coast Guard officials in Sault Ste. Marie and said they were taking on water. Later, a blizzard obscured the Fitz on the Anderson’s radar, but Captain Ernest McSorley, who was on his final voyage before retirement, assured a crew member on the Anderson at 7:10 p.m. that, “We are holding our own.” It was the last anyone heard from McSorley or the Fitzgerald.

7. NO DISTRESS SIGNAL WAS SENT.

After that, there was nothing on the radar. No radio contact. The ship was approximately 15 miles north of Whitefish Point when it seemingly vanished. Captain Cooper, on the Anderson, was in contact with the Coast Guard and made it to Whitefish Point sometime after 8 p.m. with no sign or word from the Fitzgerald. Later, the Anderson made its way back into the storm to search for the ship, but found only a pair of lifeboats and debris. 

8. ALL 29 CREW MEMBERS DIED. 

Along with the captain, the other crew members of the Fitzgerald included porters, oilers, engineers, maintenance workers, cooks, watchmen, deck hands, and wheelsmen. Most crew members were from Wisconsin, Michigan, Ohio, and Minnesota.

9. THERE IS STILL NO DEFINITIVE EXPLANATION FOR THE SINKING.

The treacherous weather conditions are an obvious factor, but experts differ on what they think specifically caused the accident. Following the wreck, the U.S. Coast Guard and National Transportation Safety Board agreed that the tragedy was likely due to faulty cargo hatches, which led to flooding. Predictably, there are still those who harbor other theories, including unsecured hatches, maintenance troubles, massive waves, structural issues, and yes, even aliens. Author and Great Lakes historian Frederick Stonehouse posited that the ship likely hit a shoal and took on too much water before plunging into Lake Superior.

10. THE TRAGEDY WAS IMMORTALIZED BY A CANADIAN FOLK SINGER.

Gordon Lightfoot, who had released 10 albums from 1966 to 1975, was inspired to write the ballad “The Wreck of the Edmund Fitzgerald” after reading an article about the tragedy in Newsweek. He included the song on his 1976 album Summertime Dream, and the nearly six-minute single reached #2 on the Billboard Hot 100 charts that year and became Lightfoot’s second-most successful hit.

11. FAMILY MEMBERS REQUESTED A SYMBOLIC MEMORIAL FROM THE SHIP.

The U.S. Navy and Coast Guard deployed planes and cutters with magnetic anomaly detectors, sidescan sonar, and sonar survey to find the wreckage. In May, a Navy underwater recovery vehicle was sent to the site, and on May 20, 1976, the ship was spotted 535 below the surface of the lake.

In the decades since, only a handful of people have been able to see the wreck, which lies in two pieces. A pair of divers made their way down in 1995, the same year a crew—with help from the Canadian Navy, the National Geographic Society, Sony, and the Sault Ste. Marie Tribe of Chippewa Indians—retrieved the ship's bell at the behest of the families of those who were lost. The Canadian government has since prohibited access to the site. 

In eerie archival tapes below, you can hear Anderson skipper Jesse Cooper correspond with the Coast Guard, and see video of the wreck.

12. THERE'S AN ANNUAL REMEMBRANCE DAY.

The annual Edmund Fitzgerald memorial ceremony takes place on November 10th at the Great Lakes Shipwreck Museum at Whitefish Point. The recovered and restored bell will toll 29 times for each member of the Fitzgerald's crew, and a 30th for the estimated 30,000 mariners lost on the Great Lakes.
