Historical Context
The Legacy of Canadarm
Canada’s involvement in space robotics began with the original Canadarm, which first flew on the Space Shuttle in 1981. Over its 30-year operational history, Canadarm proved invaluable for deploying and retrieving satellites, supporting spacewalks, and conducting various in-orbit operations. The arm’s success established Canada as a leader in space robotics technology.
The original Canadarm, officially known as the Shuttle Remote Manipulator System (SRMS), was a 15-meter-long robotic arm that became an iconic symbol of Canada’s contribution to space exploration. It played a crucial role in numerous space shuttle missions, including the deployment and servicing of the Hubble Space Telescope.
Canadarm2 and the International Space Station
Building on the achievements of its predecessor, Canadarm2 was launched to the International Space Station (ISS) in 2001. This larger, more advanced robotic arm has been instrumental in the assembly and maintenance of the ISS. Canadarm2 introduced new capabilities such as the ability to “walk” along the station’s exterior and perform more complex tasks.
Canadarm2, also known as the Space Station Remote Manipulator System (SSRMS), is 17.6 meters long and has seven motorized joints. It has been a critical component of the ISS, assisting with the installation of new modules, capturing and berthing visiting spacecraft, and supporting astronauts during spacewalks.
The Lunar Gateway Project
Overview of the Lunar Gateway
The Lunar Gateway is an international project led by NASA to establish a small space station in orbit around the Moon. This outpost will serve as a staging point for both robotic and crewed exploration of the lunar surface and, eventually, deeper space missions. The Gateway represents a crucial step in humanity’s return to the Moon and preparation for future missions to Mars.
The Gateway will be much smaller than the International Space Station, with an internal volume of about 40 cubic meters. It will consist of several modules, including a Power and Propulsion Element, a Habitation and Logistics Outpost, and various international contributions such as the European System Providing Refueling, Infrastructure and Telecommunications (ESPRIT) module.
Canada’s Contribution
