Cosmic Origins Spectrograph

Page
The Cosmic Origins Spectrograph (COS) is a science instrument that was installed on the Hubble Space Telescope during Servicing Mission 4 (STS-125) in May 2009. It is designed for ultraviolet (90–320 nm) spectroscopy of faint point sources with a resolving power of ≈1,550–24,000. Science goals include the study of the origins of large scale structure in the universe, the formation and evolution of galaxies, and the origin of stellar and planetary systems and the cold interstellar medium. COS was developed and built by the Center for Astrophysics and Space Astronomy (CASA-ARL) at the University of Colorado at Boulder and the Ball Aerospace and Technologies Corporation in Boulder, Colorado.

COS Optical Layout. FUV and NUV channels initially share a common path. The first optic is either a concave, holographically ruled diffraction grating that directs light to the FUV detector (red) or a concave mirror directing light to the NUV gratings and the NUV detector (purple). The green colored ray packets represent the FUV optical paths, and blue colored ray packets represent the NUV optical paths. A wavelength reference and flat field delivery system is shown at top left (orange ray packets) and can provide simultaneous wavelength reference spectra during science observations.

The Hubble Space Telescope is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.
