Apollo Lunar Module Descent Stage
Modularized Equipment Stowage Assembly

The Apollo Lunar Module descent stage Modularized Equipment Stowage Assembly (MESA) filled Quad I of the LM descent stage.  In the G-Series mission (Apollo 11) and H-Series missions (Apollos 12, 13, & 14) it was packed with equipment needed to explore and study the lunar surface (camera and geology equipment, mainly).  Later on the J-Series missions (Apollos 15-17) it also carried some parts of the Lunar Roving Vehicle, as well as supplies for extended lunar stay time by the LM crew (LiOH cans, PLSS batteries, etc.).
