30.07 NASA Turns 55: Iconic Moments in America�s Space Program

WASHINGTON, July 29 (Suleiman Wali for RIA Novosti) � Spurred to action by the Soviet Union�s successful space program that sent the world�s first satellite into orbit, US President Dwight Eisenhower knew that America needed a more organized and focused effort that could compete with the country�s Cold War adversary. That realization led to the creation 55 years ago of the National Aeronautics and Space Administration (NASA).

With the Cold War over, and with space cooperation replacing the space race, NASA has had many milestones since its creation in 1958�the early ventures of which were initiated merely to keep up with the Soviets.

Here are 15 iconic moments in NASA�s 55-year history.

1. After Russia launched the world�s first satellite, Sputnik (Russian for �traveling companion�), NASA immediately began work on its own design. Following three months of development, Explorer 1 was launched and began circling the earth 12 times per day for a dozen years. Here, the scientists who created the satellite hold up a full-scale model of Explorer 1 in Washington in 1958, after confirmation that it was successfully in orbit.
