After Neil Armstrong took “one small step for a man, one giant leap for mankind” on July 20, 1969, NASA began looking for its next mission to push the bounds of exploration and discovery. At the time, NASA Administrator Thomas Paine dreamed of an ambitious exploration of space, including a piloted expedition to Mars. However, NASA was facing budget cuts and waning public support for the space program. With political support from the Air Force, NASA decided to develop a space shuttle program, which would feature reusable spacecraft that would enable regular missions to space. President Richard Nixon authorized NASA to develop the space shuttle program on January 5, 1972. The first shuttle launch took place nine years later, with the launch of Space Shuttle Columbia (STS-1) on April 12, 1981.
The space shuttle was the world’s first reusable spacecraft, and it was large enough to carry and deploy satellites, which were of particular interest to the military. During the 30 years of the space shuttle program, NASA carried out thousands of scientific experiments in space, studying human health, engineering, astronomy and physics. It also transported the materials for and the astronauts who built the International Space Station, which still operates today.
Across 135 missions, the space shuttle program suffered two accidents. The Challenger and Columbia memorials honor these astronauts who “lost their lives while furthering the cause of exploration and discovery.”
