 The GATV was first successfully launched for Gemini 8 on March 16, 1966, permitting the first successful docking in space.GATV-8 was later used as the secondary Agena target for Gemini 10, which also docked with its own GATV.GATV-9 failed to orbit when the Atlas suffered a control malfunction, forcing a similar reschedule of the Gemini 9A mission using a backup Augmented Target Docking Adapter atop an Atlas, but with no Agena rocket stage.
