On the evening of Jan. 31, 1958, the United States orbited its first satellite — Explorer 1. The effort was part of the nation’s participation in the International Geophysical Year (IGY), a peaceful scientific endeavor. It also marked America’s first step in the Space Race of the Cold War.
Project Gemini is often referred to as the “bridge to the Moon.” It spanned the period between Project Mercury, America’s first efforts to determine if humans could survive in space, and the Apollo lunar landing flights. Looking back across a half-century, Gemini proved to be a bridge to the future.
The year 1967 began with the tragic loss of the Apollo 1 crew, but ended with the successful launch of the first Saturn V rocket. NASA hoped to make it two successes in a row with the first unmanned flight of the lunar module, or LM, the spacecraft designed to land Americans on the Moon before the end of the decade.
