The Soviet Union inaugurated the “Space Age” with its launch
of Sputnik, the world’s first artificial satellite. The spacecraft,
named Sputnik after the Russian word for “satellite,” was
launched at 10:29 p.m. Moscow time from the Tyuratam launch
base in the Kazakh Republic.

Sputnik had a diameter of 22 inches and weighed 184 pounds
and circled Earth once every hour and 36 minutes. Traveling 
its elliptical orbit had an  at 18,000 miles an hour. It transmitted
radio signals back to Earth strong enough to be picked up by
amateur radio operators. Those in the United States with access
to such equipment tuned in and listened in awe as the beeping
Soviet spacecraft passed over America several times a day.

In January 1958, Sputnik’s orbit deteriorated, as expected, and
the spacecraft burned up in the atmosphere.

apogee (farthest point from Earth) of 584 miles and a perigee (nearest point)
of 143 miles. Visible with binoculars before sunrise or after sunset, Sputnik transmitted radio signals back to Earth strong enough to be picked up by

Explorer  6

From the Atlantic Missile Range in Cape Canaveral, Florida, the U.S.
unmanned spacecraft Explorer 6 is launched into an orbit around the
earth (above). The spacecraft, commonly known as the “Paddlewheel”
satellite, featured a photocell scanner that transmitted a crude picture
of the earth’s surface and cloud cover from a distance of 17,000 miles
and was received in Hawaii after nearly 40 minutes.

The first image taken by Explorer 6 shows a sunlit area of the
Central Pacific Ocean and its cloud cover.

On this day in 1958, Explorer 1 became the United States’ first
satellite in space. The launch of the satellite — twice the size
of a basketball — was an important moment for the country,
as the Space Race with the Soviet Union was just beginning.

The three men responsible for the success of Explorer 1, at left is Dr. William H. Pickering, former director of JPL, which built and operated
the satellite. Dr. James A. van Allen, center, of the State University of Iowa, designed and built the instrument on Explorer that discovered
the radiation belts which circle the Earth. At right is Dr. Wernher von Braun, leader of the Army’s Redstone Arsenal team which built the
first stage Redstone rocket that launched Explorer 1.

On this day in 1945, Private Eddie Donald Slovik became the only
U.S. soldier since the American Civil War to be executed for
desertion.

Jefferson Davis died in New Orleans on this day in 1889. He was
the first and only president of the Confederate States of America
and the highest ranking confederate leader of the South.

On this day in 1957, America’s first attempt at putting a satellite into
orbit failed when the Vanguard TV-3 launch vehicle lost thrust after
lift-off and exploded on the launch pad at Cape Canaveral, FL. The
launch was in response to the Soviet Union’s orbiting of Sputnik l.
