Workers help maneuver the Fine Guidance Sensor Scientific Instrument Protective Enclosure or FSIPE cover alongside the Orbital Replacement Unit Carrier for installation.

In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center, workers help maneuver the Fine Guidance Sensor Scientific Instrument Protective Enclosure, or FSIPE, cover alongside the Orbital Replacement Unit Carrier, or ORUC, for installation. The ORUC is one of three carriers that are being prepared for the integration of telescope science instruments, both internal and external replacement components, as well as the flight support equipment to be used by the astronauts during the fifth and final Hubble servicing mission, STS-125. Launch is targeted for Oct. 8. PHoto credit: NASA/Jack Pfaller
