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

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.
