MDA Space Ltd. signs a C$688-million contract with the Canadian Space Agency (CSA) to build and deliver a synthetic aperture radar satellite. Multiple outlets say the satellite is intended to operate as part of Canada’s Radarsat Constellation Mission, including working alongside Radarsat constellation satellites that were built and launched by MDA Space in 2019. The agreement follows a prior CSA contract worth C$44.7 million for “long lead” components awarded last year, which helped enable work toward the larger satellite program. Reporting also describes the new spacecraft as an advanced replenishment satellite for the Radarsat constellation, supporting continuity of radar Earth-observation capabilities. Separately, Quartz reports that MDA Space is buying a Raytheon satellite business unit for about US$620 million in an all-cash deal, which the outlet links to manufacturing and defense-contract positioning. Across the coverage, the CSA satellite contract is presented as a significant procurement for Canada’s radar space infrastructure, while details on timing, launch schedule, and technical specifications beyond the radar and constellation support role are not uniformly specified in the provided summaries.
