, with a twofold mission (). 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

The AMOS effort formally began with an amendment to an existing ARPA order with the

'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.
