Stage Set for Tomorrow's Spacewalk to Install Canada's Work Platform

Press Release From: Canadian Space Agency
Posted: Saturday, June 8, 2002

The Shuttle astronauts are getting ready to unwrap Canada's latest contribution to the International Space Station. Astronauts Franklin Chang-Diaz and Philippe Perrin are scheduled to begin their first spacewalk tomorrow to start the complex process of installing Canada's Mobile Base System on the International Space Station. The base is a work platform that will transport Canadarm2, as well as other space structures and equipment, along rails that will run the length of the International Space Station.

Around 4 p.m. EDT on Sunday, June 9 Canadarm2 will reach into the Shuttle's cargo bay and grapple the Mobile Base, allowing power to flow from the arm to the base. This will mark the first time Canadarm2 will handle a powered payload.

The astronauts will then remove thermal blankets that have been keeping the base warm, in preparation for installing it on top of the U.S.-built Mobile Transporter, which will carry it along the rails. By the end of the day Canadarm2 will have pulled the 1450-kilogram base out of the cargo bay and parked it in its overnight position next to the Transporter.

The Mobile Base System is the second element of Canada's contribution to the Space Station, following Canadarm2, which was installed last year.
