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.

Hubble Archive - Servicing Mission 4, STS-125
Read moreHubble's fifth and final servicing mission, Servicing Mission 4, launched on May 11, 2009 on Space Shuttle Atlantis as part of the STS-125 mission.During SM4, two new scientific instruments were installed – the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3). Two failed instruments, the Space Telescope Imaging Spectrograph (STIS) and the Advanced Camera for Surveys (ACS), were brought back to life by the first ever on-orbit repairs. With these efforts, Hubble has been brought to the apex of its scientific capabilities. To prolong Hubble's life, new batteries, new gyroscopes, a new science computer, a refurbished fine guidance sensor and new insulation on three electronics bays were also installed over the 12-day mission with five spacewalks. ||
