cs and Space Technology is responsible for the continued
             development of advanced technology. This office set the guidelines for NASA's objectives,
             demonstrates the feasibility of the objectives, and proposes the necessary technology to carry
             them out. It also coordinates activities with other agencies to prevent duplication of effort.
             The office of Space Science and Applications directs the study of the nature of the
             universe through research in astrophysics, biology, Earth sciences, solar system exploration,
             communications, micro gravity, and information systems. This office uses a vairety of devices to
             conduct its research. These include remote sensing equipment, automated spacecraft, sounding
             The Office of Space Flight is responsible for the space laboratories and all facets of the
             Space Transportaion System, or space shuttles of NASA. This office also directs several of the
             field installations and oversees the purchase of all hardware necessary for NASA's space
             The office of Space Tracking and Data Systems Provides all the information necessary
             for the commencement and progress of space missions. The facilities that provide this
             information support are the Deep Space Network, the Space flight Tracking and Data Network,
             and the Tracking and Data Relay Satellite systems. A global communications system coordinates
             the tasks of this office by linking all tracking sites, control centers, and data processing
             facilities.NASA has nine chief field installations. Many people who follow space launches know
             of the Lyndon B. Johnson Space Center in Houston, Tex., and the John F. Kennedy Space Center
             at Cape Canaveral, Fla. The Houston installation is a command control center, while the center
             at Cape Canaveral is the primary launching site.
             The other field installations are: Ames Research Center at Moffet Field, Calif.; Goddard Space
             Flight Center in Greenbelt, Md.; the Jet Propulsion L...
