SpaceX Falcon 9 RADARSAT June 12, 2019

A trio of satellites built for Canada's RADARSAT program were launched that plan to replace the aging RADARSAT-1 and 2. The new satellites contain Automated Identification System (AIS) for locating ships. The mission was originally scheduled to lift off in February but due to the landing failure of booster B1050, this flight was switched to B1051 (used on SpX-DM1) and delayed to allow refurbishment and transport to the West coast. The booster landed safely through fog. A payload cost of roughly $1 billion made this SpaceX's second most expensive payload launched and most valuable commercial payload so far put into orbit.
