Reference excerpt

The Maui Space Surveillance Complex (MSSC) is a U.S. Space Force operating location for the 15th Space Surveillance Squadron and the Air Force Research Laboratory (AFRL) at Haleakala Observatory on Maui, Hawaii, with a twofold mission (608). First, it conducts the research and development mission on the Maui Space Surveillance System (MSSS) at the MSSC. Second, it oversees operation of the Maui High Performance Computing Center (MHPCC). AFRL's research and development mission on Maui was formally called Air Force Maui Optical Station (AMOS) and the Air Force Maui Optical and Supercomputing observatory; the use of the term AMOS has been widespread throughout the technical community for over thirty years and is still used today at many technical conferences. The main-belt asteroid 8721 AMOS is named after the project.

Origins The MSSS was first envisioned as an optical research observatory in the early 1950s. It was initiated by the Advanced Research Projects Agency (ARPA, later DARPA) in 1961 as the ARPA Midcourse Optical Station (AMOS). It was first proposed by R. Zirkind of ARPA's staff for imaging ballistic missile payloads and decoys during their midcourse phase, and other space objects including satellites, in the infrared spectrum, as well as for performing astronomical research. Its location on Mount Haleakala was nearly ideal for its altitude high above much obscuration by water vapor, for its midcourse location between the missile launch site at Vandenberg Air Force Base and its main reentry location at Kwajalein Atoll, and for its low-latitude location which was advantageous for observing satellites. The AMOS effort formally began with an amendment to an existing ARPA order with the University of Michigan's Institute for Science and Technology, which was to design, construct, and operate the facility. This amendment defined the AMOS goals as follows: "(1) Identification and signature of space objects; (2) an active program to advance the state of the art in infrared technology and high-resolution imagery; (3) a research program in geophysics and astrophysics including the astronomical community." Design was completed in 1963, and physical plant construction begun by the Army Corps of Engineers. Construction was complete by 1967, after which the telescopes and control systems were evaluated, calibrated, and tested until mid 1969. In 1969, AMOS potential had been demonstrated, and the Air Force took charge as ARPA's agent. The University of Michigan was replaced by industrial contractors, and numerous system improvements and additions then took place over subsequent years. In 1984, DARPA transferred it to the Air Force, which renamed it as MSSS in 1995.

Maui Space Surveillance System (MSSS) 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 § List of discovered minor planets).

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.

Worked examples

Example 1 — a first encounter with Maui Space Surveillance Complex

Start with the simplest possible case. Write down what Maui Space Surveillance Complex claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Maui Space Surveillance Complex before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Maui Space Surveillance Complex ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Maui Space Surveillance Complex

In research: Maui Space Surveillance Complex appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Maui Space Surveillance Complex in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Maui Space Surveillance Complex is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1993 establishments in Hawaii, Astronomical observatories in Hawaii, Buildings and structures in Maui County, Hawaii, so understanding it makes those chapters shorter.
In everyday life: Look for Maui Space Surveillance Complex outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
