S88-42092 (15 July 1988) --- STS-26 Discovery, Orbiter Vehicle (OV) 103, rollover at Kennedy Space Center (KSC) is closely monitored by engineers and technicians in the late stages of the move from the orbiter processing facility (OPF) to the vehicle assembly building (VAB) as preflight preparations continue. A large crowd of KSC employees and other spectators watches in the background as OV-103, supported by its landing gear, is pulled toward VAB (background). While in the VAB, OV-103 will be mated to two solid rocket boosters (SRBs) and an external fuel tank.

STS-41 crewmembers conduct Detailed Supplementary Objective (DSO) 0472 Intraocular Pressure on the middeck of Discovery, Orbiter Vehicle (OV) 103. Mission Specialist (MS) William M. Shepherd rests his head on the stowed treadmill while Pilot Robert D. Cabana, holding Shepherd's eye open, prepares to measure Shepherd's intraocular pressure using a tono pen (in his right hand). Objectives include: establishing a database of changes in intraocular pressures that can be used to evaluate crew health; validating ten degree head down bedrest as a model for cephalad fluid shifts in microgravity; facilitating the interpretation of data by providing a quantative measure of microgravity induced cephalad fluid shifts; and validating the tono pen as an effective tool for diagnostic and scientific data collection.

STS-29 Discovery, Orbiter Vehicle (OV) 103, solid rocket booster (SRB) right aft segment is being prepared for stacking in the Kennedy Space Center (KSC) Vehicle Assembly Building (VAB). Technicians examine and work with SRB seal from scaffolding platform. The twin sets of boosters provide 80 percent of the space shuttle launch thrust. Each SRB is made up of four "loaded" or fueled segments. The SRBs operate in parallel with the space shuttle main engines (SSMEs) for the first two minutes of flight providing additional thrust needed to escape the gravitational pull of the Earth. At an altitude of approximately 24 nautical miles, the SRBs separate, descend on parachutes, and land in the Atlantic Ocean where they are recovered and reused on future flights.

KENNEDY SPACE CENTER, FLA. - Stephanie Stilson, vehicle manager for Space Shuttle Discovery (OV-103), is interviewed by the news media at the Kennedy Space Center (KSC) Shuttle Landing Facility (SLF). The interview followed the touchdown of Discovery, atop a modified Boeing 747 Shuttle Carrier Aircraft (SCA), on runway 15 at the SLF at about 10:00 a.m. EDT. The cross-country ferry flight became necessary when two days of unfavorable weather conditions at KSC forced Discovery to land on runway 22 at Edwards Air Force Base, Calif., on Aug. 9 following mission STS-114. On the return trip, stops were made at Altus Air Force Base, Okla., and Barksdale Air Force Base, La., where Discovery stayed for two nights. The SCA and Discovery will be towed to the Mate_Demate Device at the SLF where a crane will lift Discovery from the SCA and place it on solid ground. Discovery will then be towed to the Orbiter Processing Facility where preparations will begin for its next flight, STS-121.

KENNEDY SPACE CENTER, FLA. -- The space shuttle Discovery is towed toward the Orbital Processing Facility, or OPF, where processing Discovery for another flight begins. Towing normally begins within four hours after landing and is completed within six hours unless removal of time-sensitive experiments is required on the runway. In the OPF, turnaround processing procedures on Discovery will include various post-flight deservicing and maintenance functions, which are carried out in parallel with payload removal and the installation of equipment needed for the next mission. Before post-flight deservicing can continue beyond initial safing operations, certain vehicle systems must be mechanically secured and access platforms installed. Discovery completed mission STS-120 with an on-time landing at 1:01 p.m. EST. Photo credit: NASA/Jim Grossmann

KENNEDY SPACE CENTER, FLA. --In the Space Station Processing Facility at NASA's Kennedy Space Center, an overhead crane moves the integrated cargo carrier-lite, or ICC-L, toward the payload canister at right. The ICC-L is an unpressurized cross-bay carrier providing launch and return transportation with the space shuttle. It rests on a keel yoke assembly, seen underneath. The ICC-L carries three elements: a nitrogen tank assembly that is part of the external active thermal control system on the International Space Station, the European technology Exposure Facility composed of nine science instruments and an autonomous temperature measurement unit, and the SOLAR payload designed for sun observation. The SOLAR will be transferred and stowed on the Columbus module during the third spacewalk of the mission. STS-122 is targeted for launch on Dec. 6 on space shuttle Atlantis.
