Mission OverviewNavigation arrow
The purpose of the mission was to confirm all aspects of the lunar landing mission exactly as it would be performed, except for the actual landing. Additional objectives included verification of lunar module systems in the lunar environment, evaluation of mission-support performance for the combined spacecraft at lunar distance, and further refinement of the lunar gravitational potential.

Mission Activities Navigation arrow
No formal scientific experiments were planned, but engineering tests were performed, considerable photography was obtained, and landmark tracking data were gathered to reduce the size of the landing ellipse. The major activity for this mission was, of course, the simulated lunar landing with the lunar module.
