During the Russo-Japanese War, Port Arthur, the Russian naval
base in China, fell to Japanese naval forces under Admiral
Heihachiro Togo. It was the first in a series of defeats that by
June turned the tide of the imperial conflict irrevocably against
Russia.

In February 1904, following a Russian rejection of a Japanese plan
to divide Manchuria and Korea into spheres of influence, Japan
launched a surprise naval attack on Port Arthur, decimating the
Russian fleet. In the subsequent fighting, Japan won a series of
decisive victories over the Russians, who underestimated the
military potential of its non-Western opponent.

In a surprisingly low-key and carefully worded statement, President
Harry S. Truman (above) informed the American people that the
Soviets exploded a nuclear bomb. The Soviet accomplishment,
years ahead of what was thought possible by most U.S. officials,
caused a panic in the American government. 

The United States developed the atomic bomb during the latter
stages of World War II and dropped two bombs on Japan in August
1945.

The Hubble Space Telescope was launched into low Earth orbit in
1990 and remains in operation. It was not the first space telescope,
but it is one of the largest and most versatile, renowned both as a
vital research tool and as a public relations boon for astronomy.

The Hubble telescope is named after astronomer Edwin Hubble
(below) and is one of NASA’s Great Observatories.

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.
