Space

Human beings have dreamed of exploring space for centuries, but the realization of that vision in the 20th century had its roots in military thinking. From the rocket technologies developed in Germany during World War II to the use of satellite imagery and communications during the Global War on Terrorism, space exploration and the military have repeatedly intertwined. This entry discusses the links between the U.S. military and technological innovations related to the space program.

These connections began early in the Cold War. After 1945, the Soviet Union and United States vied for the services of German scientists and engineers who had developed V-2 rockets for the Nazis during World War II. The Americans successfully lured Wernher von Braun and others to come to the United States to bolster the nation’s munitions program. He soon envisioned using rocket technologies to send human beings and spacecraft into the cosmos, but these dreams also had implications for the Cold War rivalry with the Russians. Satellites might perform military reconnaissance missions, and exploration of space could lead to celestial military bases or colonies. In the 1950s, both sides sought symbolic victories along the way to these goals, launching a “space race” that showcased Soviet and American technologies before the eyes of the world.

He has just deployed the Early Apollo Scientific Experiments Package. In the foreground is the Passive Seismic Experiment Package; beyond it is the Laser Ranging Retro-Reflector; in the center background is the U.S. flag; in the left background is the black-and-white lunar surface television camera; and in the far right background is the Lunar Module “Eagle.” Astronaut Neil A. Armstrong, commander, took this photograph with a 70-millimeter lunar surface camera.

Many of these early triumphs went the Soviets’s way. They launched Sputnik, the first orbiting satellite, in 1957. President Dwight Eisenhower, though confident of American missile superiority and unimpressed by space gadgetry, faced pressure to support the creation of the National Aeronautics and Space Administration (NASA) the following year. Although NASA is a civilian agency, it maintained strong ties with the military; all the astronauts who journeyed into space until 1972 served with the U.S. armed forces. Eisenhower’s more aggressive successor, John F. Kennedy, declared in May 1961 that the United States would land a man on the moon before the end of the 1960s. The pledge materialized in the wake of the embarrassing debacle at the Bay of Pigs in Cuba and the first successful space flight of the Soviet cosmonaut Yuri Gagarin.

STSS-Demo was launched at 8:20:22 a.m. Eastern Daylight ime by National Aeronautics and Space Administration for the U.S. Missile Defense Agency. The STSS-Demo is a space-based sensor component of a layered ballistic missile defense system designed for the overall mission of detecting, tracking, and discriminating ballistic missiles. STSS-Demo is capable of tracking objects after the boost phase and provides trajectory information to other sensors.
