The PMM is a large, reusable pressurized element that was originally used to ferry cargo back and forth to the station. It added 2,472 additional cubic feet of pressurized volume for storage and for scientific use, and it can hold up to 16 racks of equipment, experiments and supplies. It also has an end-cone that has additional storage space for cargo bags and other items.
