At a lab at NASA's Kennedy Space Center, a Lockheed Martin technician prepares an electrical wiring harness during a procedure to solder the pins to the socket of the replacement feed-through connector that will be installed in the external fuel tank for space shuttle Atlantis' STS-122 mission. Two United Launch Alliance technicians, who performed this exacting task on the Centaur upper stage for Atlas and Titan launches in 1994, will be doing the soldering. Soldering the connector pins and sockets together addresses the most likely cause of a problem in the engine cutoff sensor system, or ECO system. Some of the tank's 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 soldering is completed and the connector is reinstalled, shuttle program managers will decide on how to proceed. The launch date for mission STS-122 is under review.
