					International Space Station
Did you know that, even though the International Space Station (ISS) is in orbit more than 400 km
above the Earth, it is visible to the naked eye from Canada and most other countries? The birth of this
new star in our skies represents the most ambitious engineering project ever undertaken by
humanity—the result of an unprecedented international effort.

Canada is contributing an essential component of the International Space Station, the Mobile
Servicing System (MSS). The MSS consists of three main elements: the Space Station Remote
Manipulator System (SSRMS), known as Canadarm2, the Mobile Base System (MBS), and the
Special Purpose Dexterous Manipulator (SPDM), known as Dextre.

International Space Station
Canada is one of the international partners working with the United States, Russia, Japan and 11
nations, members of the European Space Agency, to construct the largest and the most sophisticated
international engineering project ever undertaken, the International Space Station.

The International Space Station will provide scientists and engineers with ongoing access to the unique
microgravity (very low gravity) environment of space. As a permanent space laboratory, the ISS will
allow scientists and engineers to use this unique venue to discover entirely new materials, crystals and
processes that would not otherwise be achieved. Research will be conducted in a variety of fields such
as life sciences, materials, Earth observation and astronomy.

It will also establish a permanent human presence in space and result in the acquisition of knowledge
required to conduct human missions to Mars and beyond.

Participating countries   United States, Russia, Japan, Canada, and 11 European countries (Belgium,
                          Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden,
                          Switzerland and the United Kingdom).
Canada's contribution          The mobile servicing system (MSS), which includes three elements:
                                 the robotic arm Canadarm2, the mobile base system and the special
                                 purpose dexterous manipulator Dextre
                               The Canadian Space Vision System
                               The ground segment, the MSS Operations Complex is located at the
                                 Canadian Space Agency headquarters in Longueuil, Quebec. This
                                 complex provides the infrastructure, resources, equipment and
                                 expertise required for monitoring and analysis of MSS operations in
                                 space, training of ISS crew members and ground crew, logistic
                                 support and flow of MSS operations in real-time processing.

Scheduled date of         2010
Number of missions        Over 50 missions will be required to transport and assemble all parts of the
required                  ISS.
Number of spacewalks          About 160 spacewalks, that is, 960 hours, will be required for station
required                  assembly and maintenance.
                              In April 2001, Canadian Space Agency Astronaut Chris Hadfield became
                          the first Canadian to perform a spacewalk (extravehicular activity, or EVA)
                          when he installed Canadarm2 on the ISS.

                                It will have 1,250 cubic metres of living and working space, which is
                                 the equivalent of the interior of a Boeing 747, about the size of three
                                 average Canadian houses.

First modules        Zarya, launched in November 1998, and Unity, launched in December 1998
Power generation     With an acre wing area for the solar arrays, it will generate 110 kilowatts
Cost                 The cost of designing, developing, and installing the mobile servicing system
                     on the station is about $1.4 billion over 20 years (1984 to 2004), or about
                     three dollars a year per Canadian taxpayer.
Benefits                  Economic benefits worth about $6 billion are expected from Canada's
                             participation in the International Space Station, with 70,000 person-
                             years of employment.
                          Contracts worth $919 million have been awarded to the Canadian
                             aerospace industry to date, generating $2.8 billion in benefits and

Assembly Stages

Working in space
By contributing the Mobile Servicing System (MSS) to the International Space Station (ISS), Canada
acquires rights for the use of the Space Station for scientific and technological research. To ensure that
we can make use of this sophisticated orbiting laboratory, the Canadian Space Agency established the
Physical Science in Space Program. The program gives researchers in companies and universities
experience in designing and building experiments and equipment for space. It also provides funding for
the training and equipment needed for space research. Thanks to this program, Canada will have a
research and industry community ready to use our allocated Space Station resources effectively.

To train astronauts and mission controllers, the Canadian Space Agency has built an MSS Operations
Complex (MOC) at its headquarters in Longueuil, Quebec. The MOC is a state-of-the-art centre that
includes a number of operation and training facilities: the Space Operations Support Centre, the MSS
Simulation Facility, the Kinematic Operations Simulator, and the Canadian MSS Training Facility. Each
plays a unique role either in supporting ISS mission planning and operations, or in training operators to
use and maintain Canadarm2. Controllers will use the MOC to plan complex Canadarm2 manoeuvres
before they are performed in orbit. They will also monitor the condition of the MSS and its complex
hardware and software systems. ISS astronauts and cosmonauts from many countries will visit the
MOC to learn about the MSS and how to operate it in the demanding space environment.

Part of our future

Special Purpose Dexterous Manipulator

Canada's destiny is in space. Space is the most demanding environment for developing the nation's
science and engineering resources and capacity. It stretches our capabilities and helps us become
better in all we do. In striving to meet the challenges of space, we learn to solve problems on earth,
and we stand to gain from the unimagined breakthroughs. Information from space is vital to our
understanding of the fragile planet Earth. From space, we can monitor changes on earth's surface, and
in its life-giving atmosphere. The Space Station is our first permanent foothold in space: an orbiting
laboratory for the unexplored science of microgravity; an observation post to monitor earth's
constantly changing environment; a unique space-based technology test bed; and a platform to explore
the distant stars and the heavens. Canada's contribution to the International Space Station Program
ensures that we will be part of mankind's greatest adventure. Like the explorers of the past, we know
not precisely where we shall land, but we voyage forth in the knowledge that great rewards await us.
