The cone-shaped command module is divided
into three compartments: forward, crew, and aft. The forward compartment
is at the cone's apex, the crew compartment is in the center,
and the aft compartment is in the base, or blunt end, of the craft.
The forward compartment contained the parachutes and recovery
equipment. The aft compartment is divided into 24 bays by the
structural supports. It contains 10 reaction control engines,
fuel, oxidizer and helium tanks for the roll, pitch and yaw thrusters,
and the crushable ribs of the impact attenuation system. The crew
compartment has a volume of 5.9 cubic meters (210 cubic feet).
It contains three couches for the crew during launch and landing.
The couches are arranged so that each astronaut faces the main
instrument panel. During flight, the astronauts could fold-up
the couches to make more room in the spacecraft. Near the feet
of the couches, in the lower equipment bay, there is enough room
to stand up.
