supports: The Institute for Astronomy (IfA) is a research unit within the University of Hawaii system, led by Günther Hasinger as Director. IfA main headquarters are located at 2680 Woodlawn Drive in Honolulu, Hawaii, , on the University of Hawaii at Mnoa campus. Additional facilities are located at Pukalani, Maui and Hilo on Hawaii island (the Big Island). IfA employs over 150 astronomers and support staff. IfA astronomers perform research into solar system objects, stars, galaxies and cosmology.  The island of Maui (Hawaiian: ) is the second-largest of the Hawaiian Islands at 727.2 square miles (1,883 km) and is the 17th-largest island in the United States. Maui is part of the State of Hawaii and is the largest of Maui County's four islands, bigger than Molokai, Lnai, and unpopulated Kahoolawe. In 2010, Maui had a population of 144,444, third-highest of the Hawaiian Islands, behind that of Oahu and Hawaii Island. Kahului is the largest census-designated place (CDP) on the island with a population of 26,337 and is the commercial and financial hub of the island. Wailuku is the seat of Maui County and is the third-largest CDP . Other significant places include Khei (including Wailea and Makena in the Kihei Town CDP, which is the second-most-populated CDP in Maui), Lahaina (including Kanapali and Kapalua in the Lahaina Town CDP), Makawao, Pia, Kula, Haik, and Hna. The Air Force Research Laboratory (AFRL) is a scientific research organization operated by the United States Air Force Materiel Command dedicated to leading the discovery, development, and integration of affordable aerospace warfighting technologies, planning and executing the Air Force science and technology program, and provide warfighting capabilities to United States air, space, and cyberspace forces. It controls the entire Air Force science and technology research budget which was $2.4 billion in 2006. Haleakal (Hawaiian: ), or the East Maui Volcano, is a massive shield volcano that forms more than 75% of the Hawaiian Island of Maui. The western 25% of the island is formed by another volcano, Mauna Kahalawai, also referred to as the West Maui Mountains. The Haleakal Observatory on the island of Maui, also known as the Haleakal High Altitude Observatory Site, is the location of Hawaii's first astronomical research observatory. It is owned by the Institute for Astronomy of the University of Hawai'i, which operates some of the facilities on the site and leases portions to other organizations. Tenants include the Air Force Research Laboratory (AFRL) and the Las Cumbres Observatory Global Telescope Network (LCOGTN). At over in altitude, the summit of Haleakal is above one third of the Earth's atmosphere and has excellent astronomical seeing conditions. Astronomical seeing refers to the blurring and twinkling of astronomical objects such as stars caused by turbulent mixing in the Earth's atmosphere that causes variations of the optical refractive index. The "astronomical seeing" conditions on a given night at a given location describe how much the Earth's atmosphere perturbs the images of stars as seen through a telescope. Hawaii is the 50th and most recent state to have joined the United States of America, having received statehood on August 21, 1959. Hawaii is the only U.S. state located in Oceania and the only one composed entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean. Hawaii is the only U.S. state not located in the Americas. The 3.67 m Advanced Electro Optical System Telescope is a Department of Defense telescope at Haleakala Observatory . The telescope is part of the Maui Space Surveillance Complex ( MSSC ) , which in turn is part of the Air Force Maui Optical and Supercomputing Site ( AMOS ) . The 3.67 - meter telescope , known as the Advanced Electro - Optical System ( AEOS ) , owned by the Department of Defense , is the United States ' largest optical telescope designed for tracking satellites . The 75 - ton AEOS telescope points and tracks very accurately , yet is fast enough to track both low - Earth satellites and ballistic missiles . It can slew at nearly 20 degrees per second . It is an f / 200 and has an extremely narrow field of view . AEOS can be used simultaneously by many groups or institutions because its light can be channeled through a series of mirrors to seven independent coudé rooms below the telescope . Employing sophisticated sensors that include an adaptive optics system , radiometer , spectrograph , and long - wave infrared imager , the telescope tracks man - made objects in deep space and performs space object identification data collection . AEOS is equipped with an adaptive optics system , the heart of which is a 941 - actuator deformable mirror that can change its shape to remove the atmosphere 's distorting effects . Scientists are expected to get near diffraction - limited images of space objects .
