Russia launches Sputnik 1, the world's first artificial satellite, in 1957
In October 1957, the former Soviet Union, using an A-model two-stage rocket, successfully launched the world's first artificial satellite into Earth orbit. This brilliant achievement startled the world, and the United States, caught up in the Cold War with the former Soviet Union, stepped up its own preparations to launch an artificial satellite. But a month later another Soviet satellite was launched, Sputnik 2, which carried the dog Laika. And six months after that the 1.3-ton Sputnik 3 entered orbit, keeping the Russians one step ahead of the US.

The US also advances into outer space with the launch of Explorer 1 in 1958
Lagging behind the Russians, the US hoped to launch a satellite with a Vanguard launch vehicle developed by the US Navy, but the attempt failed. US President eisenhower then directed the Army team, under Werner von Braun, to make a launch effort. Three months later, in January 1958, a Jupiter-C launch vehicle successfully carried the 14- kilogram satellite, Explorer 1, into orbit. Thus both the Soviet Union and then the United States had advanced into space, and the space development race between the two countries had begun.
