View of the Pressurized Mating Adapter - 2 (PMA-2) Androgynous Peripheral Docking System (APDS). The APDS appears to have various surface anomalies. The "3" petal appears to have multiple scratches and two MMOD stikes on its surface. There is also visible fluorocarbon degradation on the planar Trajectory Control Sensor (TCS) retroreflector. View was taken during flyaround and approach by the STS-120 crew prior to docking.
