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.
Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit. The Block 5 variant is the fifth major interval aimed at improving upon the ability for rapid reusability.See Falcon Details
The Falcon 9 first stage core B1051 will attempt to land at LZ-4.Result: Successful Return to Launch Site landing at Landing Zone 4.
Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.INFO WIKI
