This space project is delayed, over budget and still waiting on a launch date. But despite the issues facing the Radarsat Constellation Mission (RCM), the MDA built-project will fill a growing need in northern climes to monitor the effects of climate change, an analyst notes, because CubeSats can’t fill the hole yet.
The $1 billion CDN ($750 million) constellation was supposed to lift off in February, but an issue with a SpaceX Falcon 9 booster during a December 2018 launch delayed RCM for the sixth time; a new launch date has not been announced yet.
