ASSEMBLY PHASES

The assembly of the Space Station would not be possible without Canada’s contribution, which takes the form of a complex robotics system known as the Mobile Servicing System (MSS). The MSS is made up of three main components: Canadarm2 (also known as the Space Station Remote Manipulator, or SSRMS), the Mobile Remote Maintenance Unit (MBS) Base, and the Specialized Agile Remote Manipulator (SPDM) . The Mobile Servicing System will play an essential role in the in-orbit construction of the Station as well as during the ten years of its operation.
