CAPE CANAVERAL, Fla. - Technicians in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center check the Fine Guidance Sensor, or FGS, as it is lifted from its stand. The sensor will be moved to the Orbital Replacement Unit Carrier or ORUC, for installation. An FGS consists of a large structure housing a collection of mirrors, lenses, servos, prisms, beam splitters and photomultiplier tubes. There are three fine guidance sensors on Hubble located at 90-degree intervals around the circumference of the telescope. Along with the gyroscopes, the optical sensors are a key component of Hubbles highly complex but extraordinarily effective “pointing control system.” 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, on space shuttle
