	Advanced Camera for Surveys - Wikipedia, the free encyclopedia
		The Advanced Camera for Surveys (ACS) is a third generation axial instrument aboard the Hubble Space Telescope (HST).
		ACS was assembled and tested extensively before launch at Ball Aerospace and Technologies and the Goddard Space Flight Center and underwent a final flight-ready verification at the Kennedy Space Center before integration in the cargo bay of the Columbia orbiter.
		It was launched on March 1, 2002 as part of Servicing Mission 3B (STS-109) and installed in HST on March 7, replacing the Faint Object Camera (FOC).
