The Advanced Camera for Surveys (ACS) will be installed in the Hubble SpaceTelescope during the fourth servicing mission (SM-3B), which is nowscheduled for November 2001. By the time of the AAS meeting, the SolarBlind Camera, the High Resolution Camera, and the Wide Field Camera willhave been installed and tested in the ACS. In this paper we describe theACS and its different imaging modes, and predict the performance of thethree cameras.
