In 1998, NASA’s Launch Services Program (LSP) was established to support NASA’s science and robotic missions by procuring commercial launch vehicles. The program was established at NASA’s Kennedy Space Center to centralize technical and management support to spacecraft customers. LSP brings together people, procurement, engineering best practices, strategic planning, studies, and cutting-edge techniques—all instrumental components for the United States to have a dependable and secure Earth-to-Space bridge that is dedicated to launching all types of spacecraft.
