ESA strikes ahead with Concord



Following the choice of three Earth Explorer candidate missions to enter a primary feasibility research in September 2018, ESA has chosen one of many candidates, Concord, to maneuver to the subsequent section of improvement. Concord is envisaged as a mission with two satellites that orbit in formation with one of many Copernicus Sentinel-1 satellites to handle key scientific questions associated to ocean, ice and land dynamics.

Earth Explorers are analysis missions making use of new commentary strategies to reply to the wants of the scientific neighborhood of their quest to grasp completely different elements of the Earth system and the interactions that bind the system as an entire. Advancing science and know-how, they tackle questions which have direct bearings on societal points equivalent to the provision of meals, water, power and assets, public well being and local weather change.

Three ideas, Daedalus, Concord (previously referred to as Stereoid) and Hydroterra (previously referred to as G-Class), have spent the final 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 Statement (PB-EO) accepting ESA’s proposal, based mostly on the advice from the Advisory Committee for Earth Statement (ACEO) and its personal analysis that Concord ought to be taken ahead to the subsequent research section.

This section, Part-A, consists of additional feasibility evaluation after in-depth system definition, together with the design of the satellite tv for pc platform and devices, flight operations, know-how developments and the way finest to use the information.


Josef Aschbacher, Director of ESA’s Earth Statement Programmes, mentioned, “Concord is an thrilling idea and we’re thrilled to have it shifting to the subsequent step for additional design consolidation and feasibility evaluation. We count on {that a} agency choice on full implementation, that means improvement by to launch and commissioning, shall be taken in autumn 2022 by ESA Member States, upon completion of Part-A actions.”

The Concord idea includes two similar satellites that might fly in convoy with a Copernicus Sentinel-1 satellite tv for pc. Every Concord satellite tv for pc is being designed to hold a receive-only artificial aperture radar as its most important instrument. Working along with Sentinel-1’s radar, Concord would offer knowledge to measure small shifts within the form of the land floor equivalent to these associated to earthquakes and volcanic exercise, thereby contributing to danger monitoring. It will additionally permit for the research of 3D deformation and circulate dynamics of glaciers on the quickly altering marginal zones of the ice sheets for a greater understanding of sea-level rise.

Each Concord satellites would additionally carry a multibeam thermal-infrared instrument, which within the presence of clouds will allow the measurement of height-resolved cloud actions. In absence of clouds, this multibeam thermal-infrared instrument will measure sea-surface temperature variations.

Concord would even be the primary mission to offer knowledge to enhance our understanding of interactions between the air and the ocean floor by offering simultaneous measurements of wind, waves, currents, that along with measurements of sea floor thermal variations and cloud movement will allow an unprecedented view of the marine atmospheric boundary layer.

In essence, Concord addresses key science questions in a number of domains. Its commentary idea permits distinctive measurements over timescales starting from tens of milliseconds (to measure ocean currents) to years (to measure strong Earth floor movement).

Dr Aschbacher added, “Although the advice of ACEO had additionally included Daedalus as a possible Part-A candidate, it was not proposed for choice as a result of strict adherence to the fee constraints established by the PB-EO. Nonetheless, ACEO recommended each Daedalus and Hydroterra mission ideas for the exploratory nature of their observations and doubtlessly ground-breaking science goals.

“ESA plans to discover choices to additional research the Daedalus idea in a distinct framework, by potential worldwide cooperation. In the meantime, some risk-reduction research will proceed on each Daedalus and Hydroterra with a purpose to additional mature every idea.”
