KENNEDY SPACE CENTER, FLA.  --  On Launch Pad 39A, a technician explains how test equipment -- the blue monitor -- will be used to validate the circuit on test wiring from the electrical harness in space shuttle Atlantis' aft main engine compartment connected with the engine cut-off system.  The test wiring leads from the tail mast on the mobile launcher platform to the interior where the Time Domain Reflectometry, or TDR, test equipment will be located to test the sensor system.

KENNEDY SPACE CENTER, FLA.  -  During power-up of the orbiter Discovery in the Orbiter Processing Facility, a technician (left) looks at the circuit breaker lights in the cabin.  Discovery has been undergoing Orbiter Major Modifications in the past year, ranging from wiring, control panels and black boxes to gaseous and fluid systems tubing and components.  These systems were deserviced, disassembled, inspected, modified, reassembled, checked out and reserviced, as were most other systems onboard.  The work includes the installation of the Multifunction Electronic Display Subsystem (MEDS) - a state-of-the-art “glass cockpit.”

KENNEDY SPACE CENTER, Fla.  --  In the Orbiter Processing Facility bay 3, STS-120 crew members get a look at the main bus switching unit that is part of the payload on their mission.  From left are Pilot George Zamka, Mission Specialists Scott Parazynski and Stephanie Wilson,  astronaut Dan Tani, who will join the International Space Station crew, and Mission Specialists Paolo Nespoli, Doug Wheelock and Commander Pam Melroy.  Nespoli represents the European Space Agency.  A main bus switching unit is used for power distribution, circuit protection and fault isolation on the space station's power system.  The units route power to proper locations in the space station, such as from solar arrays through umbilicals into the U.S. Lab.  The unit will be installed on the external stowage platform 2 attached to the Quest airlock for temporary storage.  Discovery is targeted to launch mission STS-120 no earlier than Oct. 20.

KENNEDY SPACE CENTER, FLA. -- At Launch Pad 39A, a team of external tank specialists from Lockheed Martin and the United Space Alliance undertakes the task of removing the hydrogen feed-through connector in support of space shuttle Atlantis' STS-122 mission.  Here, a technician pulls the connector assembly, with its associated electrical harness, away from the tank.   Some of the tank's engine cutoff sensors, or ECO sensors, failed during propellant tanking for launch attempts on Dec. 6 and Dec. 9.  Results of a tanking test on Dec. 18 pointed to an open circuit in the feed-through connector wiring, which is located at the base of the tank. The feed-through connector passes the wires from the inside of the tank to the outside.  After the data from additional testing on the connector is analyzed, shuttle program managers will decide on a forward plan.  Launch of STS-122 is targeted for January 2008.

Results of a tanking test on Dec. 18 pointed to an open circuit in the feed-through connector wiring, which is located at the base of the tank. The pins in the replacement connector were precisely soldered to create a connection that allows sensors inside the tank to send signals to the computers onboard Atlantis.
