text1: The primary camera on the Hubble Space Telescope has shut down and is likely to only be restored to partial functionality, according to reports from the National Aeronautics and Space Administration (NASA). The camera on the telescope, known as the "Advanced Camera for Surveys" or ACS, can be reactivated but will be restored to only one-third of its operating capacity. The restoration will probably take place in mid-February. The camera shut down over the weekend, probably due to a failure of its backup power supply. It was the third such shutdown of the camera in the past calendar year. The camera had been operating on its backup power since June 30, 2006, when engineers switched from the primary power supply ("Side A") to the backup ("Side B") due to a malfunction. A review board was convened on January 29 to assess all options and to decide on a course of action. Their findings will be reported to NASA on March 2, 2007. The ACS, developed jointly by four American agencies, was installed in March of 2002.
