Inspection of a Kurs antenna on the Progress 23 unpiloted cargo carrier that docked at the aft end of the station's Zvezda Service Module on 26 October 2006 was the next task. Final latching of the spacecraft to the station during the docking procedure was delayed by more than three hours because Mission Control Moscow was not sure the antenna was completely retracted. Tyurin and López-Alegría moved to the rear of Zvezda and photographed the antenna. It was still fully extended, so Tyurin used a screwdriver to release a latch and tried to retract the antenna. Russian flight controllers also tried to retract it by activating a motor. Neither succeeded, and the task was abandoned.
