The sign next to the cockpit mockup. It reads
Lunar Module Cockpit
This is a full-size mock-up of the interior of a lunar module. It is identical
in appearance to the cockpits of the lunar modules that landed on the Moon.
The two astronauts stand before the windows as they control the craft during
descent to the lunar surface, and later, during ascent from the Moon.
The lunar module attitude is controlled by 16 rockets which can be fired
automatically or manually.
