The JEM (Japanese Experiment Module) - a.k.a. Kibo - consisting of three modules, is the Japanese segment of the international space station ISS.
The Experiment Logistics Module (ELM) takes a roll of an on orbit storage area which accommodates experiments or consumables. The Pressurized Module and the Exposed Facility each accommodates ELM. The ELM can also serve as a transportation container, it can be detached from ISS, returned to Earth by a Space Shuttle and be relaunched to space with cargo, although this capapbility was never used.
When the Experiment Logistics Module Pressurized Section (ELM-PS) is launched for the first time, it will be used as a container to carry experiment racks and system racks. Once on orbit, it will be mainly used as a storage facility. System devices, tools to be used for maintenance of experiment devices, materials for experiments or spare items for trouble are stored inside the ELM-PS. The ELM-PS volume is less than that of the PM. A total eight racks can be accommodated, but all of them are just stored.
Kibo was launched by three separate Space Shuttle missions, and the ELM-PS was the first of Kibo's components to be launched to orbit. When Kibo assembly was completed on orbit, ELM-PS was attached to the top of the PM. However, since it was launched prior to the PM, it was first attached to the Node 2 with a common berthing mechanism. When PM arrived on orbit, the ELM-PS was moved to its normal position.
