Summary
RADARSAT Constellation launched on a SpaceX Falcon 9 Block 5 from Space Launch Complex 4E, Vandenberg SFB, CA, USA on June 12, 2019. It was SpaceX's 80th launch, 7th this year and humanity's 5,857th orbital launch attempt. It was the 16th Falcon 9 Block 5 flight and the 6th this year. Booster B1051 flew for the 2nd time and landed at Landing Zone 4. The payload was bound for Sun-Synchronous Orbit (SSO). RCM 1, one of 3 catalogued objects, reached a 594 × 611 km orbit inclined 97.8°. 3 objects from this launch are catalogued, all of them payloads.

About this launch
The Radarsat Constellation Mission is a follow-on project to RADARSAT-2 currently developed by MDA. The constellation will consist of a fleet of three spacecraft, and be both complementary and a follow-on to the upcoming deployment of the RADARSAT-2 mission. The primary purpose of the RCM is to provide C-Band data continuity for RADARSAT-2 users, as well as adding a new series of applications enabled through the constellation approach. The main uses of RCM are expected to be in the areas of: maritime surveillance (ship detection, ice monitoring, and oil spill detection), disaster management, ecosystem monitoring. The primary areas of interest are the landmass of Canada and its surrounding Arctic, Pacific and Atlantic maritime areas. The images and derived information are required to be provided to Canadian government users at frequent area coverage rates. Contrary to the earlier RadarSat missions, the imagery will not be available commercially. The spacecraft Payload will consist of a Synthetic Aperture Radar (SAR) sensor integrated with an Automated Identification System (AIS). The SAR Payload concept is a 2-panel deployable SAR antenna of length approximately 7 meters.
