Marking the end of an era, spacewalkers Andrew Feustel and John Grunsfeld removed the no-longer-needed COSTAR corrective optics package from the Hubble Space Telescope today and replaced it with the Cosmic Origins Spectrograph, an $88 million state-of-the-art instrument designed to study the large-scale structure of the universe.

The Cosmic Origins Spectrograph, comprised two instruments, one of which was developed in conjunction with CASA University of Colorado Boulder and UC Berkeley’s Space Sciences Lab. The detector and electronics package were built here at our lab. The full article on the COS instrument installation is found here.
