schmidt telescope inaugurated in 1973 at siding spring observatory in central New South Wales, Australia. With its 1.2-m (48-in.) corrector plate and 1.8-m (72-in.) spherical mirror, the instrument was modelled on the oschin schmidt telescope at Palomar Observatory. The UKST was an outstation of the royal observatory, edinburgh until 1988, when its close relationship with the nearby anglo-australian telescope was formalized and it became part of the anglo-australian observatory. Its principal task during its first two decades was to conduct photographic surveys of the entire southern sky in various wavebands, which were then digitized at Edinburgh. In the early 1980s, experiments with fibre optics led to new modes of operation for the telescope, culminating in 2001 with the deployment of a robotic 150-object spectroscopy system known as 6dF.
United States Geological Survey (USGS) Sole science agency for the US Department of the Interior. Its Flagstaff Field Center was established in Arizona in 1963, originally for lunar studies and training astronauts for the apollo programme in geology. Since then, Flagstaff's activities have expanded to include the study of the origin and evolution of the terrestrial planets and the major satellites of the Solar System, the development of techniques of remote sensing and image processing to aid in the interpretation of planetary surfaces, and to produce topographic and geological maps of planetary bodies.
