Mission Objective

Primary object was rendezvous and docking and to evaluate EVA. Secondary objective included: Tethered vehicle operation, perform 14 experiments, rendezvous and dock in 3rd revolution, demonstrate automatic reentry, perform docked maneuvers, practice docking, conduct system tests and to park Gemini Agena target vehicle GATV-12 in 555.6 km (300nm) orbit.  



November 11, 1966 3:46:33.419 pm EST. Nov 15, 1966. Landed at 24deg 35min North 69deg 57min West. Miss distance was 4.8km (2.6 nm) 

Mission Highlights

EVA time 5 hours, 30 min. All primary objectives and most secondary objectives were met. Docked maneuvers were canceled due to a propulsion anomaly during Gemini Agena target vehicle (GATV) insertion. The GATV was not placed in a 555.6km orbit because its attitude control gas was depleted by earlier maneuvers.
