Another objective of the mission was to rendezvous and fly in formation with the spent second stage of its Titan II booster rocket. However the crew found it difficult to target the stage due to the lack of depth perception and with no radar on board. After several attempts to get closer and with half the thruster fuel spent, the crew finally gave up and focus on the more important EVA objective. The rendezvous objective was achieved successfully in later Gemini mission by Wally Schirra commanding Gemini 6A in December.
