PS2 and PS1 telescopes atop Haleakalā on the island of Maui, Hawaii


Pan-STARRS — the Panoramic Survey Telescope And Rapid Response System — is a system for wide-field astronomical imaging developed and operated by the Institute for Astronomy at the University of Hawaii. Pan-STARRS1 (PS1) is the first part of Pan-STARRS to be completed and is the basis for Data Release 1 (DR1).  The PS1 survey used the 1.8 meter PS1 telescope and its 1.4 Gigapixel camera (GPC1) to image the sky in five broadband filters (g, r, i, z, y). The PS1 Science Consortium funded the operation of the Pan-STARRS1 telescope, situated at Haleakalā Observatories near the summit of Haleakalā located on  on the island of Maui, Hawaii for the purposes of astronomical research. The PS1 consortium is made up of astronomers and engineers from 14 institutions from six countries.

The data from PS1 are archived at the Space Telescope Science Institute (STScI) in Baltimore Maryland, and can be accessed through MAST, the Mikulski Archive for Space Telescopes. Additional support for the PS1 public science archive is provided by the Gordon and Betty Moore Foundation.

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.  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.
