Canadian Payloads and Expedition Two Crew En Route to the International Space Station

Press Release From: Canadian Space Agency
Posted: Thursday, March 8, 2001

Space Shuttle Discovery blasted into space today carrying Canada's H-Reflex science experiment, a Canadian robotic work station and the Expedition Two crew, all destined for the International Space Station (ISS).

"While much of the attention will be focussed on the exchange of the ISS crew when Discovery reaches its destination in space, there are also important Canadian payloads being delivered," said W.M. (Mac) Evans, President of the Canadian Space Agency. "The H-Reflex experiment, which will be Canada's first experiment on the ISS, and the Robotic Work Stations, from which Canadarm2 will be operated, are key Canadian contributions to this multinational mission."

The Hoffman Reflex, or H-Reflex, experiment, directed by Dr. Douglas Watt of McGill University, will help us to understand exercise requirements for astronauts during extended spaceflights. It may also lead to improvements in managing balance disorders on Earth, particularly in the elderly. The experiment will be performed over a period of several months both on the Shuttle and on the Station. Three Expedition Two crewmembers and at least one of the Expedition Three crewmembers will participate in the experiment.

"As a partner in the International Space Station project, Canada has access to this unique laboratory in space," said Mr. Barry Wetter, Director General of the Canadian Space Agency's Space Science Program. "The Canadian Space Agency facilitates access to the ISS and supports Canadian research that will impact on the health and safety of astronauts and benefit Canadians on Earth."

An additional Canadian component, the Robotic Workstations (RWS), developed by MacDonald Dettwiler Robotics (MDR) under contract to NASA are being brought to the ISS. The RWS are the control stations designed to provide an operator with a capability to control and monitor the Space Station Remote Manipulator System (SSRMS), now known as Canadarm2. The Robotic Workstations are built to provide a highly reliable, seamless interface between man and machine and feature display and control panels, hand controllers, video monitors and computers. Two flight units will be installed on the ISS. One will be located in the U.S. Lab Module, while the other will function as a back-up workstation in the Cupola.

All this preparatory work will culminate in April with the delivery, installation and operation of Canada's main contribution to the ISS, Canadarm2. Another milestone of Canada's Space Program will be marked when Canadian Space Agency Astronaut Chris Hadfield performs the first Canadian spacewalk to install Canada's next-generation robotic arm on the ISS.
