At NASA's Kennedy Space Center, the payload canister is in the Canister Rotation Facility where it will be lifted to a vertical position. The canister transporter will then carry the canister and its cargo to Launch Pad 39A. The cargo consists of four carriers holding various equipment for the STS-125 mission aboard space shuttle Atlantis to service NASA’s Hubble Space Telescope. At the pad, the cargo will be moved into the Payload Changeout Room. The changeout room is the enclosed, environmentally controlled portion of the rotating service structure that supports cargo delivery to the pad and subsequent vertical installation into the shuttle’s payload bay. Launch of Atlantis is targeted for Oct. 10. Photo credit: NASA/Jack Pfaller
