    Hubble?s Advanced Camera for Surveys, out of commission for almost two weeks after its primary power supply failed, is back to normal. NASA engineers were able to switch the camera to a backup power supply. The Advanced Camera for Surveys, or ACS, is Hubble?s newest instrument, installed in 2002. Its expanded wavelength range allows it to see in light ranging from ultraviolet to infrared. It was designed to study some of the earliest activity in the universe.
