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:
“History does nothing; it does not possess immense riches, it does not fight battles. It is men, real, living, who do all this.... It is not “history” which uses men as a means of achieving—as if it were an individual person—its own ends. History is nothing but the activity of men in pursuit of their ends.”
—Karl Marx (1818–1883)
“To care for the quarrels of the past, to identify oneself passionately with a cause that became, politically speaking, a losing cause with the birth of the modern world, is to experience a kind of straining against reality, a rebellious nonconformity that, again, is rare in America, where children are instructed in the virtues of the system they live under, as though history had achieved a happy ending in American civics.”
—Mary McCarthy (1912–1989)
“While the Republic has already acquired a history world-wide, America is still unsettled and unexplored. Like the English in New Holland, we live only on the shores of a continent even yet, and hardly know where the rivers come from which float our navy.”
—Henry David Thoreau (1817–1862)
