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)
“A man will not need to study history to find out what is best for his own culture.”
—Henry David Thoreau (1817–1862)
“You treat world history as a mathematician does mathematics, in which nothing but laws and formulas exist, no reality, no good and evil, no time, no yesterday, no tomorrow, nothing but an eternal, shallow, mathematical present.”
—Hermann Hesse (1877–1962)
