STS 30 - Space Shuttle Projects
Summary
The STS-30 patch depicts the joining of NASA's manned and unmanned space programs. The sun and inner planets of our solar system are shown with the curve connecting Earth and Venus symbolizing the shuttle orbit, the spacecraft trajectory toward Venus, and its subsequent orbit around our sister planet. A Spanish caravel similar to the ship on the official Magellan program logo commemorates the 16th century explorer's journey and his legacy of adventure and discovery. Seven stars on the patch honor the crew of Challenger. The five-star cluster in the shape of the constellation Cassiopeia represent the five STS-30 crewmembers - Astronauts David Walker, Ronald Grabe, Norman Thagard, Mary Cleave and Mark Lee - who collectively designed the patch.
The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
