The Lincoln Near-Earth Asteroid Research (LINEAR) project is a collaboration of the

Lincoln Laboratory's Experimental Test Site (ETS) on the White Sands Missile Range (WSMR) near Socorro, New Mexico
.

History

In the late 1970s, the Lincoln Laboratory's Experimental Test Site facility (observatory code

Ground-based Electro-Optical Deep Space Surveillance (GEODSS). The wide-field Air Force telescopes were designed for optical observation of Earth-orbiting spacecraft. Initial field tests used a 1024 × 1024 pixel charge-coupled device (CCD) detector. While this CCD detector filled only about one fifth of the telescope's field of view, four near-earth objects were discovered. A 1960 × 2560 pixel CCD which covered the telescope's two-square degree field of view was then installed, and both detectors were used in later tests.[7]

The first LINEAR telescope became fully operational in March 1998.[8] Beginning in October 1999, a second 1.0 m telescope was added to the search effort.[9] In 2002, a 0.5 m (20 in) telescope equipped with the original CCD was brought on-line to provide follow-up observations for the discoveries made by the two search telescopes.[10] This allowed about 20% more of the sky to be searched each night. Data recorded by the telescopes is sent to a Lincoln Laboratory facility at Hanscom Air Force Base in Lexington, Massachusetts for processing. Detections are then forwarded to the Minor Planet Center.[2]
