America Enters Space
Date: 31 Jan 1958

America entered space for the first time with the launch of Explorer 1. The 14-kg (30.8-pound) satellite carried instruments that confirmed the existence of radiation trapped in Earth's atmosphere, dubbed the Van Allen Radiation Belt.

Explorer used a Jupiter-C rocket, a modification of the Redstone ballistic missile.
