Advanced Camera for Surveys (ACS) produced many of the most popular and dramatic images from the Hubble Space Telescope over the last few years, but in January 2007 the instrument had a serious power failure which caused the three observing channels, the Wide Field Channel, The Solar Blind Channel and the High Resolution channel, to cease operation. The Solar Blind Channel was returned to service in February 2007. This animation shows how the Servicing Mission 4 astronauts will attempt to repair the Advanced Camera for Surveys by replacing the CCD electronics box in the Wide Field Channel and power this box with a replacement low voltage power supply. If this repair is successful, ACS will again provide the most sensitive images available at visible and near-infrared wavelengths.
