At Launch Pad 39A, a United Space Alliance technician carefully cuts away the foam insulation surrounding the covers over the feed-through connector box on the external tank for space shuttle Atlantis' STS-122 mission. The covers will be removed for access to the feed-through connectors. Following the failure of some of the tank's engine cutoff sensors, or ECO sensors, during propellant tanking for launch attempts on Dec. 6 and Dec. 9, a tanking test was conducted on Dec. 18 to aid in troubleshooting the cause. Technicians spliced test wiring into the ECO sensor electrical system and used time domain reflectometry equipment to help locate the electrical anomaly. Results of the tanking test 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. During the holiday period, workers from Lockheed Martin will begin inspecting and testing the connector. Shuttle program managers will meet on Dec. 27 to review the test and analysis, and decide on a forward plan. Photo credit: NASA/Kim Shiflett
