Abstract
The Cosmic Origins Spectrograph (COS) is a candidate instrument for installation on the Hubble Space Telescope in 2002. COS will bring the full diagnostic power of ultraviolet spectroscopy to bear on such fundamental issues as: • the origin of large-scale structure in the universe and the intergalactic medium • the formation, evolution, and ages of galaxies • the origins and ages of stars and planetary systems This frontier science program is made possible by moderate-resolution (R=20,000), far-UV spectra that will be obtained by COS. COS will be by far the most sensitive UV spectrograph ever flown aboard HST. It is nearly 20 times more sensitive than STIS in the comparable wavelength range, 1200–1700 Å, and spectral resolution. COS will be built by a team involving three main parties: the University of Colorado, Ball Corporation, and the Goddard Space Flight Center.
