History
The personnel of the 20th SPCS operate the Air Force Space Surveillance System and maintain the AN/FPS-85 radar, the Air Force's only phased-array radar dedicated to tracking earth-orbiting objects. The AN/FPS-85 radar can track approximately 90 percent of all manmade objects in earth orbit. The radar can track near-earth objects the size of a softball moving at 300 miles (500 km) and deep space objects the size of a basketball moving at 22,300 nautical miles (41,300 km) above earth. Located at Site C-6 on Eglin, the squadron is a geographically separated unit of the 21st Space Wing and the only Air Force Space Command unit on Eglin.

Famous quotes containing the word history:
“I cannot be much pleased without an appearance of truth; at least of possibility—I wish the history to be natural though the sentiments are refined; and the characters to be probable, though their behaviour is excelling.”
—Frances Burney (1752–1840)
“When the coherence of the parts of a stone, or even that composition of parts which renders it extended; when these familiar objects, I say, are so inexplicable, and contain circumstances so repugnant and contradictory; with what assurance can we decide concerning the origin of worlds, or trace their history from eternity to eternity?”
—David Hume (1711–1776)
“The history of philosophy is to a great extent that of a certain clash of human temperaments.”
—William James (1842–1910)
