COS will also sample the chemical content and physical state of gas in distant galaxy halos, providing important insight into the building process of early galaxies and the production of elements heavier than hydrogen and helium over cosmic time. Required to accomplish these goals is the extraordinary sensitivity of COS's far-ultraviolet channel—a factor more than 30 times greater than that of previous spectroscopic instruments for the detection of extremely low light levels. A two-fold enhancement will be offered by COS's near-ultraviolet channel.

After the implementation of three new control modes in Hubble's main computer, and major changes to Hubble's planning and scheduling system at the Space Telescope Science Institute, two-gyro operations began in 2005. By operating on two gyros, with the other gyro turned off (until needed), it is expected that Hubble can continue science operations through the end of 2008.
