STS-51 crew patch

STS-51 insignia

STS051-S-001 (January 1993) --- Designed by the crew members, the crew patch honors all who have contributed to mission success. It symbolizes NASA's continuing quest to increase mankind's knowledge and use of space through this multi-faceted mission. The gold star represents the United States Advanced Communications Technology Satellite (ACTS) boosted by the Transfer Orbit Stage (TOS). The rays below the ACTTOS represent the innovative communication technologies to be tested by this experiment. The stylized Shuttle Pallet Satellite (SPAS) represents the German-sponsored ASTROSPAS mission. The constellation Orion below SPAS is representative of the types of stellar objects to be studied by its experimenters. The stars in Orion also commemorate the astronauts who have sacrificed their lives for the space program. The ascending spiral, symbolizing America's continuing commitment to leadership in space exploration and development, originates with the thousands of persons who ensure the success of each space shuttle flight. The five large white stars, representing the five crew members, along with the single gold star, form the mission's numerical designation. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the form of illustrations by the various news media. When and if there is any change in this policy, which we do not anticipate, it will be publicly announced. Photo credit: NASA
