This document provides background information on NASA and the early US space program from 1957-1961. It summarizes that the Soviet Union's launch of Sputnik sparked the space race and concerns over national security. NASA was established in 1958 with the goal of achieving leadership in space over the USSR. Key early programs included Project Mercury to put the first American in orbit. Technological development focused on rockets like Redstone and Saturn I and spacecraft like Mercury. Political and public support for NASA grew after Yuri Gagarin's 1961 flight but was still constrained by budget debates over costs.
