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.

On June 24, 1997, U.S. Air Force officials release a 231-page report dismissing
long-standing claims of an alien spacecraft crash in Roswell, New Mexico,
almost exactly 50 years earlier.

On June 3, 1965, 120 miles above the Earth, Major Edward H. White II opens
