Fun Facts: Exploration
"Exploration is really the essence of the human spirit"
—Frank Borman (American astronaut)
With primitive ships and without navigation aids such as compasses, the
Polynesians located virtually all of the tiny islands spread over
14 million square kilometres of the Pacific Ocean, and colonized them all.
They had colonized most of modern-day Malaysia and Indonesia by 1500 B.C.,
Fiji and Tonga by 1200 B.C., Hawaii, Easter Island, and Madagascar
by 500 A.D., and New Zealand by 1000 A.D.

When the troops of ancient Egyptian Pharaoh Thutmose I invaded
Syria and Carchemish on the upper Euphrates in 1525 B.C., they
were astounded to see the Nile "falling from the sky" and the river
that "in flowing north flowed south." The soldiers had only known
the Nile and the cloudless land of Egypt, and so were fascinated to
encounter rain (the Nile falling from the sky) and the direction of
the flow of the Euphrates, which flows south, which to the Egyptians
meant "upstream", so they saw the Euphrates as flowing "backwards".

The first occasion on which humanity "used up" a natural resource
was 4,000 years ago, when the supply of tin ore, needed to make
bronze, was used up in the Middle East around 2,000 B.C. The rich
tin mines of Cornwall, England were dug in the thirteenth century B.C.
by Phoenicians looking for tin. In over 3,000 years of mining, around
three million tons of tin have been removed from the Cornish mines,
and they still have not been exhausted.

The Phoenician navigator Hanno was likely the first to circumnavigate
Africa, around 500 B.C. He observed that, at the southern end of Africa,
the noonday sun shone in the north. This observation sounded
ridiculous to the Greek historian Herodotus, who reported the tale, but
this report shows that Hanno likely either did circumnavigate Africa, or
or at least made a good attempt to do so. He likely wouldn't have
been able to imagine the sun shining in the "wrong" part of the sky if
he hadn't seen it.

In the third century B.C., the Greek geographer
and explorer Pytheas sailed along the Atlantic coast of Europe,
explored Great Britain, sailed north to "Ultima Thule" (Norway)
and traversed the Baltic Sea as far as
the Vistula. His work On the Ocean, while it has not
survived, is the earliest first-hand information
on northwestern Europe.

The
Navigatio Santi Brendani Abatis, a ninth century
manuscript, describes the many adventures of St. Brendan the
Navigator, who supposedly undertook a seven-year voyage across
the Atlantic ocean, eventually reaching what might possibly
have been Newfoundland. In 1976–77, Tim Severin, a
British scholar, crossed the Atlantic on a boat
constructed based on the details described by Brendan, showing that
such a voyage would have been possible.

It is possible that black explorers from western Africa visited America
centuries before Columbus. There is archaeological evidence that the
Olmecs, a Central American people, may have been in contact with blacks.
As well, when Columbus arrived in the New World, he heard stories about
blacks, and collected golden spearheads identical to those used in
West Africa. The Indians referred to the spearheads as "guanin",
which means "gold" in West African languages. The shorter distances
and the favourable currents would have made a trip to America from
West Africa easier than one from Spain.
The first European to see the Pacific Ocean was Vasco Núñez de
Balboa, who first saw the Pacific on September 25th, 1513.
Henry Hudson was not the discoverer of the Hudson River or Hudson Bay;
others had previously explored these areas.

Since most early literate civilisations were located around
the warm Mediterranean region,
the first mention of an iceberg in world literature did not come until
the ninth century A.D., when an account of the travels of the Irish
monk St. Brendan in the North Atlantic, three centuries before, appeared.
It mentioned that he saw a "floating crystal castle."
What else could that have been?

Due to Iceland's geographical isolation from mainland Europe,
no humans ever set foot on Iceland until mediaeval times.
The first humans to arrive on Iceland were Irish explorers,
who arrived no later than the year 795.
They established a colony, but it didn't last. By the time
the Vikings arrived eighty years later and established a permanent
settlement, only a few hermits remained.

To encourage his fellow Norsemen to go to a large, snow- and ice-covered
island that he discovered in 982 A.D., Eric the Red named
it Greenland. In a few years, twenty-five ships filled with eager
settlers sailed for the island.
(source)
The Vikings founded a settlement in North America almost 500 years
before Columbus "discovered" the New World. In the year 1000, Leif
Ericson,
son of Eric the Red, sailed from Greenland on an epic
westward voyage that took him past "Helluland" (probably Baffin
Island) and "Markland" (probably Labrador) to a land called "Vinland"
(modern-day Newfoundland). The Vikings later founded a
colony on Vinland, near the modern-day fishing village of
L'anse-aux-Meadows. However, the Vikings soon discovered that the
lands were already inhabited by "Skraelings" (probably Inuit), who
were often hostile. After a few years, the first European colony
in the New World was abandoned and the colonists sailed home.

Cheng Ho, court eunuch and great admiral of the Ming
Dynasty, led Chinese fleets on seven voyages of conquest and diplomacy,
between 1405 and 1433. As a result of Cheng Ho's voyages, which ranged
as far as West Africa, 36 countries sent tribute to China. However, in
1433, the eunuchs' opponents gained the upper hand in a power struggle
in the Chinese court, and the fleets stopped, shipyards were
dismantled, and outbound shipping was forbidden. Had these voyages
continued, it is possible that the Chinese would have "discovered"
America before Columbus.

Had Marco Polo not been captured by the Genoese and imprisoned
for a year, the tales of his historic twenty-two-year adventure in the
Far and Middle East (at the end of the thirteenth century) might never
have been collected and written down. When he returned to Venice
after his odyssey, he became a "gentleman commander" of a war vessel
striving to hold off Genoese traders. In a battle of Curzold Island,
his galley was captured and Marco was hauled off to Genoa and gaoled.
There he met a writer named Rustichello, who, after hearing Marco's
yarns, insisted that they be written down.

In the fifteenth century, Prince Henry the Navigator dispatched his
sea captains on voyages to explore the African coast. One of Henry's
hopes was that his men would discover the rich Christian kingdom of
"Prester John", which was cut off from the rest of Christendom by the
Islamic conquest. The Portuguese rounded the
Cape of Good Hope and
sailed the east coast of Africa, only to find that Prester John's
kingdom did not exist. While they found a Christian kingdom in
Ethiopia, it was dismissed as being that of Prester
John due to its poverty.

Christopher Columbus was not the only person of his time who
believed the world was round. Since the twelfth century, educated
people had been aware of the earth's actual shape. However,
Columbus thought the world was much smaller than it actually was.
He estimated the westward distance from Spain to Asia as being
about 2,500 miles, a far cry from the true distance of about 12,000
miles. Had America not been in his way, Columbus' expedition would
have ended in death on the endless sea.
Columbus visited England in 1477 and Iceland in the 1480s. It is
possible that during these visits he heard that lands lay
far to the west, across the Atlantic Ocean.
(source)
Christopher Columbus' first transatlantic voyage was accomplished at
a speed of about 2.8 miles per hour.
Prince Henry the Navigator never navigated the seas on exploring
expeditions. Henry was given this title because he ran an exploration
institute at Sagres, Portugal, where astronomers, geographers,
admirals, and shipbuilders pooled their expertise for voyages along
the African coast that culminated, long after Henry's death, when
Vasco de Gama rounded the
Cape of Good Hope
and went on to reach India, in 1497.

Ferdinand Magellan was not the first explorer to sail around the world.
During his journey, he and several of his men were killed in the Phillipines,
and one of his officers, Juan Sebastián de Elcano, led the
expedition back to Spain.

Pedro Álvares Cabral set out on March 9th, 1500,
from Portugal with the intent of rounding the Cape of Good Hope and
heading towards India. He decided to tack far across the Atlantic.
On April 22nd, he spotted a mountain, and claimed what
appeared to him to be an island in the Atlantic. He erected a cross
on the island and sent a messenger back home that he had discovered
the "Island of Vera Cruz" for Portugal. What Cabral did not realise,
however, was that this "island" was in fact Brazil, the largest
country in South America.

Kepler calculated that the first voyages to the moon would take four
hours, and thought that the passengers, in order to endure the trip,
would take narcotics.
History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a basketball, weighed only 183 pounds, and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological, and scientific developments. While the Sputnik launch was a single event, it marked the start of the space age and the U.S.-U.S.S.R space race.

Why were the first lunar missions nicknamed "Apollo"? At the height of Greek colonization of the ancient world, Apollo was seen as a god who accompanied emigrants and travelers on their way. The name "Apollo" was suggested by Abe Silverstein, an early director of the Lewis Research Center and one of the "founding fathers" of NASA's Manned Spaceflight Center (now Johnson Space Center) in Houston.

Meriweather Lewis and William Clark were not the first European
explorers to travel from the Atlantic to the Pacific. The first was
Vasco Nùñez, but he crossed the narrow isthmus of
Central America in 1513. Lewis and Clark weren't the first Europeans
to cross North America either. In 1793, the Scotsman Alexander
Mackenzie crossed Canada and reached the Pacific.
The first man ever to set foot on the continent of Antarctica was an
American sealer, John Davis. He did this on February 7, 1821, but
the fact was not known until 1955, when the log of his ship was
discovered and studied.

In 1985, NASA estimated that the probability of an accident
occurring to the space shuttle was 1 in 100,000.
However, on January 28, 1986,
only the 25th shuttle launch, Challenger exploded after
take-off, killing all seven astronauts aboard, and
on February 1, 2003,
the 113rd mission, Columbia exploded on re-entry, again
killing all seven astronauts.
Earlier estimates by other groups had estimated the
probability as being closer to 1 in 100, a probability that seems
more reasonable.
