On January 31, 1958, the United States finally succeeded in launching its first satellite, the Explorer. While Explorer was still smaller than Sputnik, it was successfully launch sent it deeper into space. Unsurprisingly, the Soviets wuickly responded with yet another launch, and the space race continued.
The success of Sputnik had a major impact on the Cold War and the United States. Fear that they had fallen behind led U.S. policymakers to accelerate space and weapons programs. In the late 1950s, Soviet Premier Nikita Khrushchev boasted about Soviet technological superiority and growing stockpiles of ICBMs, so the United States worked simultaneously to develop its own ICBMs to counter what it assumed was a growing stockpile of Soviet missiles directed against the United States. With both countries researching new technology, talk of creating a treaty banning nuclear testing faded away for several years. In this way, the launch of Sputnik fueled both the space race and the arms race, in addition to increasing Cold War tensions, as each country worked to prepare new methods of attacking the other.
