<a href="https://en.wikipedia.org/wiki/STS-123" class="extiw" title="w:STS-123">STS-123</a> continues assembly of the <a href="https://en.wikipedia.org/wiki/International_Space_Station" class="extiw" title="w:International Space Station">International Space Station</a> (ISS). The primary mission objectives include rotating an expedition crew member and installing both the first component of the Japanese Experimental Module (the Experimental Logistics Module - Pressurized Section (ELM-PS)) and the Canadian Special Purpose Dexterous Manipulator (SPDM). In addition, STS-123 will deliver various spare ISS components and leave behind the sensor boom used for inspecting the shuttle's thermal protection system. A follow-on mission to ISS will utilize and then return home with this sensor boom. A total of five spacewalks are planned to accomplish these tasks. The mission will also require the use of both the shuttle and ISS robotic arms. STS-123 will utilize the Station-Shuttle Power Transfer System to extend the docked portion of the mission to eleven days, with a total planned duration of 15 days. The crew patch depicts the space shuttle in orbit with the crew names trailing behind. STS-123's major additions to ISS (the ELM-PS installation with the shuttle robotic arm and the fully constructed SPDM) are both illustrated. The ISS is shown in the configuration that the STS-123 crew will encounter when they arrive.
