(AEOS), the Maui Space Surveillance System (MSSS), and the Ground-based Electro-Optical Deep Space Surveillance (GEODSS). The MSSS uses a number of optical assets, including a telescope, two telescopes on a common mount, a beam director/tracker, and a laser beam director. The GEODSS uses two telescopes and one telescope. Daniel K. Inouye Solar Telescope The Daniel K. Inouye Solar Telescope (DKIST) is a solar telescope of the National Solar Observatory. Future facilities The AFRL has plans to build a mirror re-coating facility adjacent to the AEOS building. Former facilities A Baker-Nunn telescope operated from 1957 to 1976 as part of Project Space Track. The Lunar Ranging Experiment (LURE) Observatory operated from 1974 until 2004. The Pan-STARRS PS1 now resides in the south dome of the LURE facility and the PS2 is being built in the north dome. The University of Chicago Enrico Fermi Institute operated the Haleakala Cosmic Ray Neutron Monitor Station from 1991 to 2007. The Haleakala Gamma Ray Observatory was a six-mirror Imaging Atmospheric Cherenkov Telescope on an equatorial mount. It began operating in 1981 and was upgraded in 1988. The Multicolor Active Galactic Nuclei Monitoring (MAGNUM) was a near infrared telescope operated by the University of Tokyo. It was housed in the LURE facility's north dome from 1998 to 2008. Observations of airglow were made from a platform near the middle of the site in the 1960s and 1970s. The platform is now used for temporary projects. The Near-Earth Asteroid Tracking (NEAT) program operated from 2000 to 2007 using one of the MSSS 1.2 m telescopes. Non-astronomical facilities The Federal Aviation Administration operates a facility immediately to the west of the observatory site. The Department of Energy also operates a facility immediately to the west of the observatory site. A small building on the site is used by the Haleakalā Amateur Astronomers.
