ESA moves forward with Harmony

on 14 April 2021

Following the selection of three Earth Explorer candidate missions to enter a first feasibility study in September 2018, ESA has chosen one of the candidates, Harmony, to move to the next phase of development. Harmony is envisaged as a mission with two satellites that orbit in formation with one of the Copernicus Sentinel-1 satellites to address key scientific questions related to ocean, ice and land dynamics.

Earth Explorers are research missions applying new observation techniques to respond to the needs of the scientific community in their quest to understand different aspects of the Earth system and the interactions that bind the system as a whole. Advancing science and technology, they address questions that have direct bearings on societal issues such as the availability of food, water, energy and resources, public health and climate change.

Three concepts, Daedalus, Harmony (formerly called Stereoid) and Hydroterra (formerly called G-Class), have spent the last two years being scrutinised as to their scientific, technical and budgetary feasibility to be ESA’s tenth Earth Explorer mission.

This step has now culminated in ESA’s Programme Board for Earth Observation (PB-EO) accepting ESA’s proposal that Harmony should be taken forward to the next study phase.
