NASA and its partners launch a US-European satellite to monitor Earth’s oceans. The project is meant to provide ocean and atmospheric data for a number of purposes. According to Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington, “Understanding tidal patterns down to the inch is critical in protecting how we use our oceans every day on Earth.” 

Two satellites make up the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission, which is the latest in a series of ocean-observing radar altimetry missions that have monitored Earth’s changing seas since the early 1990s. Key information includes wind speeds, wave heights, atmospheric temperature, and humidity.
