Mike Berger, with Lockheed Martin, examines the replacement feed-through connector for the engine cutoff, or ECO, sensor system in space shuttle Atlantis' external tank. The feed-through connector passes the wires from the inside of the tank to the outside. 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 have been precisely soldered to create a connection that allows sensors inside the tank to send signals to the computers onboard Atlantis.
