Pan-STARRS -- the Panoramic Survey Telescope & Rapid Response System -- is an innovative design for a wide-field imaging facility developed at the University of Hawaii's Institute for Astronomy.
The combination of relatively small mirrors with very large digital cameras results in an economical observing system that can observe the entire available sky several times each month.
The prototype single-mirror telescope PS1 is now operational on Mount Haleakala; its scientific research program is being undertaken by the PS1 Science Consortium - a collaboration between ten research organizations in four countries,
A major goal of Pan-STARRS is to discover and characterize Earth-approaching objects, both asteroids & comets, that might pose a danger to our planet.
Its vast database is also ideal for research in several other astronomical areas, particularly those which involve an aspect of time variability. See PS1SC key projects for examples.
