Background
Canadarm3 is an AI-assisted robotic arm contracted to MDA Space under a $1 billion agreement with the Canadian Space Agency. It was designed to maintain and service the Lunar Gateway autonomously, but Gateway's 2026 cancellation has left it without a home.
It follows in the lineage of Canadarm (shuttle era) and Canadarm2 (ISS), which secured Canada's seat at the table of major human spaceflight programmes. Unlike its predecessors, Canadarm3 was designed to operate without constant human supervision, reflecting advances in autonomous systems.
NASA and the CSA have used language about "flexibility to pivot", with the Lunar Utility Vehicle (LUV) emerging as a potential surface alternative. Whether that pivot constitutes genuine continuity or a face-saving exercise remains contested in Ottawa.
