Status: Launch Successful
Mission: Earth Science
The Sentinel-6 Michael Freilich and Sentinel-6B make up the Sentinel-6 mission, also known as Jason Continuity of Service (Jason-CS), which is a partnership between NASA, NOAA, ESA, and EUMETSAT. This mission continues the long-term global sea surface height data record begun by first Jason satellites in 1992. Named after former NASA Earth Science Division Director Michael Freilich, Sentinel-6 Michail Freilich will provide altimeter data necessary for ocean climate monitoring, ocean modelling and numerical ocean prediction, weather forecasting, marine meteorology, coastal altimetry and modelling. A secondary objective of the mission is to collect high-resolution vertical profiles of temperature, using the Global Navigation Satellite System (GNSS) Radio-Occultation sounding technique, to assess temperature changes in the troposphere and stratosphere and to support numerical weather prediction. Sentinel-6 Michael Freilich is to operate in a highly-inclined circular orbit at an altitude of 1336 km, with an operational mission lasting 5 years. Near-identical Sentinel-6B is planned to follow-up shortly after.

Falcon 9 Block 5 | RADARSAT Constellation
SpaceX | USAVandenberg SFB, CA, USA
June 12, 2019, 2:17 p.m.
Status: Launch Successful
Mission: Earth Science
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.

SpaceX’s Falcon 9 rocket will deliver 10 satellites to low Earth orbit for Iridium, a global leader in mobile voice and data satellite communications. This is the sixth set of 10 satellites in a series of 75 total satellites that SpaceX will launch for Iridium’s next generation global satellite constellation, Iridium® NEXT. Sharing this launch is the Gravity Recovery and Climate Experiment Follow-on mission, which is a joint project of NASA and the German Research Centre for Geosciences. It's goal is to track Earth's water movement to monitor changes in underground water storage, the amount of water in large lakes and rivers, soil moisture, ice sheets and glaciers, and sea level caused by the addition of water to the ocean.
