We are often asked to identify several
additional features of the Apollo 11 Command Module. The twin
eyeball-like structures (1) on the side
near the aft heatshield are vents that release waste water into
space. The hand rails under the side hatch (2)
were present during recovery (3), the white
eye ring between the hand rails was used to attach an anchor.
The recovery team did not want Columbia to float away.
The forward portion of Columbia’s heatshield was discarded
during reentry and underneath you can see the two mortars used
to eject the drogue parachutes and the three compartments that
contained the main chutes.
