END-NOTE BACKGROUND TO CANADA'S CONTRIBUTION TO THE ISS PROGRAM

摘要

Canada's contribution to the International Space Station (ISS) is the external robotics collectively called the Mobile Servicing System that comprises both a space and a ground segment. Between April and July 2001, Canadarm2 (or Space Station Remote Manipulator System), the first flight-element of Canada's contribution to the ISS, was successfully launched, installed, checked out and then used for assembly of the Station's Quest Airlock. In April 2002, the U.S. supplied MSS Mobile Transporter was positioned on-orbit paving the way for the launch, in June, of the next element of Canada's Mobile Servicing System, the Mobile Remote Servicer Base System or MBS. The final element of the MSS to be launched to the ISS was the special purpose dexterous robot called Dextre.
