Technicians monitor the movement of an IMAX 3D camera as it is lowered to be installed in space shuttle Atlantis payload bay.

In the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center, technicians monitor the movement of an IMAX 3D camera as it is lowered onto the Orbital Replacement Unit Carrier, or ORUC, to be installed in space shuttle Atlantis’ payload bay. Other equipment on the ORUC are the Fine Guidance Sensor Scientific Instrument Protective Enclosure and the Fine Guidance Sensor. The camera will record the STS-125 mission to service the Hubble Space Telescope. 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/Jack Pfaller
