Kibō consists of six major elements: 1 Pressurized Module PM, 2 Exposed Facility EF, 3 Experiment Logistics Module-Pressurized Section ELM-PS, 4 Experiment Logistics Module-Exposed Section ELM-ES, 5 Japanese Experiment Module Remote Manipulator System JEMRMS, and 6 Inter-orbit Communication System ICS2

Pressurized Moduleedit

Interior of the Pressurized Module

The Pressurized Module PM is the core component connected to the port hatch of the Node 2 Module It is cylindrical in shape and contains twenty-three International Standard Payload Racks ISPRs, ten of which are dedicated to science experiments while the remaining 13 are dedicated to Kibo’s systems and storage3 The racks are placed 6-6-6-5 along the four walls of the module The end of the JEM-PM has an airlock and two window hatches The Exposed Facility, Experiment Logistics Module and the Remote Manipulator System all connect to the pressurized module Kibo is also the location for many of the press conferences that take place on board the station

Exposed Facilityedit

Exposed Facility

The Exposed Facility EF, also known as "Terrace", is located outside the port cone of the PM which is equipped with an airlock The EF has 12 EFU Exposed Facility Unit ports that attach to PIU Payload Interface Unit connectors on EF-EEUs EF-Equipment Exchange Units All experiment payloads are fully exposed to the space environment For proper functioning of these experiments, the payload requires an ORU Orbital Replacement Unit which consists of the EPS Electrical Power System, CT Communications & Tracking and the TCS Thermal Control System Of the 12 ORUs, eight are replaceable by the JEMRMS while the other four are EVA-replaceable

Experiment Logistics Moduleedit

Experiment Logistics Module, Pressurized Section

The Experiment Logistics Module ELM includes two sections:

  • The Japanese Experiment Logistics Module, Pressurized Section ELM-PS –- also called the JLP –- is a pressurized addition to the PM The module is a storage facility that provides storage space for experiment payloads, samples and spare items4
  • The unpressurized external section ELM-ES serves the EF as a storage and transportation module

Remote Manipulator Systemedit

The Remote Manipulator System JEMRMS is a 10m long robotic arm, mounted at the port cone of the PM, intended to service the EF and to move equipment from and to the ELM The RMS control console was launched while inside the ELM-PS The main arm was launched with the PM The "Small Fine Arm", is 2m long and attaches to the end effector of the main arm, was launched aboard5 The free end of the arm is able to use the type of grapple fixtures that the Canadarm2 uses6

Launch sequenceedit

The EF and ELM-ES arrive at the Kennedy Space Center left Technicians work on the Remote Manipulator System at KSC right

NASA launched the JEM complex over three flights using the Space Shuttle The shuttle had a large payload bay which carried the modules into orbit along with the crew This is in contrast to the Russian modules, which are launched into orbit on multistage Proton rockets and then rendezvous and dock with the station automatically On 12 March 2007, the Experiment Logistics Module Pressurized Section ELM-PS, the main laboratory, arrived at the Kennedy Space Center KSC from Japan7 It was stored in the Space Station Processing Facility until launched into orbit aboard Space Shuttle Endeavour as part of the STS-123 mission8

At first the ELM-PS, the small cargo bay, was connected to a temporary location on the Harmony module Node 2 and later, on 6 June 2008, was moved to its final destination, or berthing location, on top zenith of the main laboratory On 30 May 2003, the Pressurized Module PM arrived at KSC from Japan9 It was stored at the Space Station Processing Facility until launched into orbit aboard Space Shuttle Discovery as part of the STS-124 mission10 On 3 June 2008 the PM was attached to the Harmony module The EF and ELM-ES arrived at KSC on 24 September 200811 The Exposed Facility EF and ELM-ES were launched on STS-127, on 15 July 200912 The ELM-ES was brought back to Earth at the end of the mission The assembly of the EF was completed during the fifth spacewalk of the mission13
