MONTREAL – Maxar Technologies (formerly MacDonald, Dettwiler and Associates Ltd.) (NYSE: MAXR; TSX: MAXR), a global technology innovator powering the new space economy, was honored to host the Prime Minister of Canada, the Right Honourable Justin Trudeau, at its Ste-Anne-de-Bellevue, Quebec, satellite manufacturing facilities on August 9 to view the final phases of construction of the RADARSAT Constellation Mission (RCM). Also on hand for the visit was Canadian Space Agency (CSA) Astronaut Jeremy Hansen.

The RCM satellites are being built for the CSA and represent the third generation of this synthetic aperture radar satellite technology that MDA has built for the Canadian government. The satellite system is designed primarily for maritime surveillance, disaster management and ecosystem monitoring and will allow Canada to keep an eye on its oceans, forests, wetlands, farmlands, natural resources, transportation corridors and ocean approaches. The three spacecraft will be launched together on a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California later this year.

During his visit, the Prime Minister helped to place a thermal blanket on one of the satellites to protect it from the extreme temperatures in space. He also witnessed the Industry 4.0 advanced digital manufacturing techniques that MDA has developed to manufacture high-tech solutions for space systems.

It was a tremendous honor to showcase our technology to the Prime Minister and share the achievements of our strong partnership with the Canadian Space Agency, said Maxar President and CEO Howard Lance. MDA has been a leader in space-based radar for five decades, now working in concert with Maxar's three other industry-leading companies to accelerate innovation for the new space economy.

The RADARSAT program, including RADARSAT-1 and RADARSAT-2, has put Canada and MDA in a global leadership position for space-based radar technology and applications, and RCM will to extend and enhance this position, said MDA Group President Mike Greenley. This program would not be possible without contributions from across MDA's facilities and employees in Richmond, Brampton, Halifax, Montreal and St. Hubert, and our supplier chain of more than 125 Canadian companies in seven provinces.
