It was the 17th manned American flight and the 25th spaceflight to that time (includes X-15 flights over 100 kilometres (62 mi). Astronauts Charles ‘Pete’ Conrad, Jr. and Richard F. Gordon, Jr. performed the first-ever direct-ascent (first orbit) rendezvous with an Agena Target Vehicle, used the Agena rocket engine to achieve a world record high-apogee earth orbit, and created a small amount of artificial gravity by spinning the two spacecraft connected by a tether. Gordon also performed two extra-vehicular activities for a total of 2 hours and 41 minutes.
