GTDA-1

  1966-046A


After the early failures with the Agena, TDA 4 was modified to become the Augmented Target Docking Adapter (ATDA), with the addition of a simple stabilization package instead of the Agena. The ATDA could be launched by a simple Atlas SLV-3 without an upper stage. It was pressed into service when TDA 5 was lost in a launch accident, but although it made orbit successfully its nose fairing failed to separate. Gemini 9-A used it as a rendezvous target, but the intended docking was called off.
