I of III :: Reentry: "Apollo Atmospheric Entry Phase" 1968

This video explains the geometry of return trajectory and reentry into the Earth’s atmosphere by the Apollo spacecraft, as well as the problems involved and the methods and actions for overcoming these problems.

Atmospheric entry is the movement of human-made or natural objects as they enter the atmosphere of a celestial body from outer space—in the case of Earth from an altitude above the Kármán Line, (100 km).

This animation primarily addresses the process of controlled reentry of vehicles which are intended to reach the planetary surface intact.
