The accessibility and capability of the Maui Space Surveillance System provides an unequaled opportunity to the scientific community by combining state-of-the-art
satellite tracking with a facility supporting research and development. The Maui Space Surveillance System, is routinely involved in numerous observing programs and has the capability of projecting
lasers into the
atmosphere. Situated at the crest of the dormant
volcano Haleakala (
IAU code 608), the observatory stands at an altitude of 3058 metres, latitude 20.7 degrees N, and longitude 156.3 degrees W. It is essentially co-located with IAU code
566, Haleakala-
NEAT/
GEODSS. Virtually year-round viewing conditions are possible due to the relatively stable climate. Dry, clean air and minimal scattered light from surface sources enable visibility exceeding 150 km. Based on double star observations, seeing is typically on the order of one
second of arc. Spanning over 30 years, the evolution of the Maui Space Surveillance System has demonstrated several stages in the history of space object tracking
telescopes. Currently, through its primary mission for the United States Space Force, Space Operations Command, (formerly, Air Force Space Command), the Maui Space Surveillance System combines large-aperture tracking optics with visible and
infrared sensors to collect data on near
Earth and deep-space objects. In the process of accomplishing its mission, the observatory has discovered a number of
asteroids
(see ).
Advanced Electro-Optical System (AEOS) 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. 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 focus 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.
Maui Optical Tracking and Identification Facility (MOTIF) The Maui Optical Tracking and Identification Facility (MOTIF) is also hosted at the MSSS site. The system consists of two 1.2-meter telescopes on a common mount. MOTIF is used primarily for Long Wave
infrared (LWIR) and photometric data collection. Other equipment at MSSS includes a 1.6-meter telescope that performs day and night tracking and imaging, a 0.8-meter beam director/tracker, and a 0.6-meter laser beam director. The telescopes accommodate a wide variety of sensor systems, including imaging systems, conventional and contrast mode
photometers, infrared radiometers, low light level video systems, and acquisition telescopes.
Ground-based Electro-Optical Deep Space Surveillance (GEODSS) The MSSS site, also hosts assets for the
Ground-based Electro-Optical Deep Space Surveillance (GEODSS) system. In addition to these assets, the site has a machine shop, optics laboratories, and electronics laboratories. A Remote Maui Experimental (RME) site at sea level houses additional optics and electronics laboratories. This secondary observation station at
Kihei bears IAU code
625 and is located at . == Maui High Performance Computing Center (MHPCC) ==
