Data

The Spacecraft was placed in an elliptical lunar orbit at 69 hours 8 minutes after liftoff. After flying two elliptical orbits of 168.5 by 60 nautical miles with an inclination of 12 degrees to the Equator, the spacecraft was placed in a nearly circular orbit of 59.7 by 60.7 nautical miles in which it remained for eight orbits. The first flight to take the men to the moon was a bold step forward to the development of lunar landing capability. . With only minor problems, all spacecraft systems operated as intended, and all primary mission objectives were successfully accomplished.
There was a timeline for the Apollo 8 to indicate the the events.
