AFSPC Milestone: USSR launched Sputnik, starting the space race

8/26/2012 - Peterson AFB, Colo. -- As Air Force Space Command approaches its 30th Anniversary on 1 Sep, here is a significant milestone which led to the creation of a new command responsible for the space domain...

On 4 October 1957, the USSR launches Sputnik I, the world's first successful artificial satellite. The surprise success of the Russian's launch began the Space Age and triggered the Space Race, a part of the larger Col War. It also lead to the launch of Explorer I, the first US satellite to go into orbit, launched from then Cape Canaveral Missile Annex, Fla. approximately 4 months later. Mercury batteries powered the high-power transmitter on Explorer I for 31 days and the low-power transmitter for 105 days. Explorer 1 stopped transmission of data on May 23, 1958 when its batteries died, but remained in orbit for more than 12 years. It has been followed by more than 90 scientific spacecraft in the Explorer series.

Additionally, the launch of Sputnik ushered in new political, military, technological, and scientific developments. The public reaction to the "Sputnik crisis" led to the creation of the Advanced Research Projects Agency (renamed the Defense Advanced Research Projects Agency or DARPA in 1972), NASA, and an increase in U.S. government spending on scientific research and education.

FIRST ROCKET LAUNCH FROM CAPE CANAVERAL

FROM:  NASA
Explanation: A new chapter in space flight began on 1950 July with the launch of the first rocket from Cape Canaveral, Florida: the Bumper V-2. Shown above, the Bumper V-2 was an ambitious two-stage rocket program that topped a V-2 missile base with a WAC Corporal rocket. The upper stage was able to reach then-record altitudes of almost 400 kilometers, higher than even modern Space Shuttles fly today. Launched under the direction of the General Electric Company, the Bumper V-2 was used primarily for testing rocket systems and for research on the upper atmosphere. Bumper V-2 rockets carried small payloads that allowed them to measure attributes including air temperature and cosmic ray impacts. Seven years later, the Soviet Union launched Sputnik I and Sputnik II, the first satellites into Earth orbit. In response in 1958,, the US created NASA.
