Components comprising the payload for space shuttle Atlantis on the STS-125 mission to service the Hubble Space Telescope are on display in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center. Seen here is the box containing the Cosmic Origins Spectrograph, or COS, on the orbital replacement unit carrier. Over 11 days and five spacewalks, Atlantis’ crew will make repairs and upgrades to the telescope, leaving it better than ever and ready for at least another five years – or more – of research. Launch of Atlantis is targeted for Oct. 10. Photo credit: NASA/Troy Cryder
