Crew members with the STS-125 mission get to service NASA's Hubble Space Telescope.

In the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center, crew members with the STS-125 mission get a close look at some of the equipment associated with their mission to service NASA’s Hubble Space Telescope. At center, Mission Specialists Mike Massimino and John Grunsfeld work with the RSU change-out tool latched in place on the Small ORU Protective Enclosure, or SOPE. At far left and far right are Johnson Space Center EVA Trainers Ron Sheffield and Kristie Hansen. The STS-125 crew is taking part in a crew equipment interface test, which provides experience handling tools, equipment and hardware they will use on their mission.
