Space exploration is about to take an exciting next step with the arrival of Canadarm3, a next-generation robotic arm for NASA’s future Gateway space station. This project, supported by a $730-million design and test contract awarded by the Canadian Space Agency (CSA), also marks a milestone for Canada’s participation in NASA’s Artemis human lunar missions.
New robotic arm in space
Robotic arms Canadarm have played a crucial role in space exploration for over 40 years. The first was used for the Space Shuttle and the first missions to the International Space Station (ISS), while a second version continues to perform maintenance work and spacewalks on the ISS. MDA Space, the manufacturer of these robotic arms, was therefore logically selected to develop Canadarm3, which will use cutting-edge technologies, including artificial intelligence, to provide a certain autonomy in the maintenance and monitoring operations of the future Gateway station.
A smart design
This new robotic system will consist of two separate arms: a main arm and a smaller secondary arm. The main arm, approximately 8.5 meters long will be designed for handling heavy loads and performing tasks requiring extended reach. It will be able to move large modules, assemble complex structures and reposition equipment in different locations on the station. It will also be able to carry out repairs and maintenance on hard-to-reach areas. The secondary arm is based on Dextre technology, a robotic tool already used on the ISS for some precision work. This smaller arm will have multiple joints allowing it to move with great flexibility and precision. It will be used for delicate tasks such as handling small tools, connecting cables and carrying out detailed repairs. Its ability to perform fine and precise movements will make it indispensable for operations where human dexterity would normally be required. Note that astronaut Jeremy Hansen will be the first Canadian to fly around the Moon in 2025 as part of the Artemis 2 mission. This opportunity is a direct result of Canada’s contribution to the development of the Canadarm3.

A modular structure
As previously mentioned, this famous robotic arm must therefore integrate the Gateway space station. Planned to play a central role in the Artemis program, Gateway will serve as research platform and relay point for manned lunar missions. In detail, this station will be modular, composed of several elements launched and assembled at regular intervals. The main modules include the Power and Propulsion Element (PPE). The latter will provide the energy and propulsion necessary to maintain the station in lunar orbit. The Habitation and Logistics Outpost (HALO) will serve as accommodation for the astronauts, with living spaces and research equipment. It will also be equipped with docking ports for visiting spacecraft. Built by the European Space Agency (ESA) and the Japan Aerospace Agency (JAXA), the International Habitation Module (I-HAB) will provide additional space for astronauts and scientific experiments. Finally, the Logistics Module will be used for the storage of supplies and equipment.
A bridge to lunar exploration and beyond
To operate, the station will be placed in cislunar orbitalso known as a Near Rectilinear Halo Orbit (NRHO). This unique orbit provides easy access to the lunar surface, particularly the Moon’s south pole, which is rich in resources such as water ice. In addition, the NRHO orbit offers good communication with Earth and the potential to function as a staging base for missions to Mars and other distant destinations. Note that in addition to its central role in the Artemis program, Gateway could serve as a model for future space stations around Mars or other celestial bodiesBy establishing a permanent infrastructure in lunar orbit, the Gateway paves the way for more ambitious missions, contributing to our understanding of space and realizing the dream of interplanetary exploration.
