Understanding changes in the Earth system and the impact that humanity is having on its delicate balance is paramount. The ability to acquire new insight into Earth-system processes poses significant scientific and technical challenges.
However, it also provides the stimulus and opportunity to develop new measurement capabilities, exploiting the unique vantage point of space to study the ebb and flow of natural processes and the impact human activity is having at local, regional and global scales.
The series of Earth Explorer satellite missions are the epitome of Europe’s technical endeavour in realising new Earth-observing capabilities. These missions offer a stream of innovative measurement techniques to explore and understand different aspects of the Earth system.
Priorities identified by the scientific community are used to guide the development of the Earth Explorer missions. Each has been selected to address and fulfil the strategic objectives of ESA’s Living Planet Programme as well as contribute critical new elements to the global Earth-observing system infrastructure.
The guiding principle of defining, developing and operating Earth Explorer missions in close cooperation with the scientific community provides a tool to address the most critical Earth-science questions in as comprehensive and effective a manner as possible.

Earth Explorer 10
In September 2018, the Daedalus, G-Class (now named Hydroterra) and Stereoid (now named Harmony) candidate missions were chosen to enter pre-feasibility study and compete to be the tenth Earth Explorer mission.
Earth Explorer 11
In May 2020, ESA issued a Call for Ideas for Earth Explorer 11.
