Missions - Sentinel Online
ESA is developing a series of next-generation Earth observation missions, on behalf of the joint ESA/European Commission initiative GMES (Global Monitoring for Environment and Security).
The goal of the Sentinel program is to replace the current older Earth observation missions which have reached retirement, such as the ERS mission, or are currently nearing the end of their operational life span. This will ensure a continuity of data so that there are no gaps in ongoing studies.
Each mission will focus on a different aspect of Earth observation; Atmospheric, Oceanic, and Land monitoring, and the data will be of use in many applications.
