Docked with orbiting Agena rocket.  The orbit was boosted to 800 km to allow the first view of the Earth as a full sphere. Gordon performed two spacewalks, one lasting about 2 hours. The first EVA was cut short (lasting a little over half an hour) due to extreme exhaustion. The second EVA was a standup EVA and much less tiring.
