Harmony[1] is a European Earth observing satellite mission projected to launch in 2029.[2] The mission concept, belonging to the ESA's FutureEO programme, comprises two identical satellites that will fly in formation with a CopernicusSentinel-1 satellite.
Both Harmony satellites will carry a receive-only synthetic aperture radar (intended to work together with Sentinel-1's radar) and a multibeam thermal-infrared instrument. Throughout the life of the mission, the Harmony satellites will be flying either in interferometric or in stereo configurations.[3]
Over land, the mission will measure small shifts in the shape of the land surface connected with volcanism and earthquakes; it will also study the dynamics of glaciers and ice sheets. Over the ocean, it will measure surface wind, waves, currents, as well as cloud movements and sea-surface temperaturedifferences.[4] Paco López-Dekker from the Delft University of Technology in the Netherlands is the Lead Investigator of the mission.[2] Florence Hélière is the Project Manager.[5]
Timeline
- In September 2018, Harmony (then named "Stereoid") was selected as one of three concepts to compete for the tenth Earth Explorer mission.[6]
- In February 2021, Harmony was chosen to be ESA's tenth Earth Explorer mission.[4]
- In March 2022, the mission concept was tested using two aircraft flying in formation over the Dutch Wadden Islands.[7]
- In September 2022, ESA Member States formally selected Harmony for implementation.[2]
- In October 2024, ESA has awarded a contract (over €280 million) to OHB to build the satellites as prime contractor.[5]
- In November 2024, OHB has selected ABB to provide thermal infrared imaging instruments for the two satellites.[8]
