Decades ago during the heady space race rivalry between the former Soviet Union and the United States, the entire world experienced the Sputnik moment when the first artificial satellite orbited the Earth.

Sputnik 1's liftoff on Oct. 4, 1957 sparked worries in the U.S., made all the more vexing by the embarrassing and humiliating failure later that year of America's first satellite launch when the U.S. Navy's Vanguard rocket went "kaputnik" as the booster toppled over and exploded.

An emotional rescue for America came via the first U.S. artificial satellite. Explorer 1 was boosted into space by the Army on Jan. 31, 1958. Nevertheless, despite setbacks, Vanguard 1 did reach orbit on March 17, 1958 as the second U.S. satellite.
