Infrared Telescope Facility
Telescopes on Maunakea are operated by 12 separate nonprofit observatories.
NASA Infrared Telescope Facility
The NASA Infrared Telescope Facility (IRTF) is one of the telescopes comprising the Maunakea Observatories on the Big Island of Hawai’i. The IRTF is a 3.0 meter telescope optimized for infrared observations. The observatory is operated and managed for NASA by the University of Hawai`i Institute for Astronomy, located in Honolulu. NASA provides the costs of operation and NSF provides funding for new focal plane instrumentation through the peer review process. Observing time is open to the entire astronomical community, and 50% of the IRTF observing time is reserved for studies of solar system objects.
University of Hawaii 2.2-meter telescope
The University of Hawaii 2.2-meter telescope is located near the summit of Mauna Kea, on the Island of Hawaii. The 2.2-meter telescope was the first large telescope constructed on Mauna Kea. It went into operation in 1970, and its early successes showed the excellent image quality and observing conditions at the top of Mauna Kea.
