N° 30–2024: EarthCARE launched to study role of clouds and aerosols in Earth's climate

ESA’s EarthCARE satellite, which is poised to revolutionise our understanding of how clouds and aerosols affect our climate with its four state-of-the-art instruments, has been launched. Just 10 minutes after it embarked on its journey, the satellite separated from the rocket and at 01:14 CEST, the Hartebeesthoek ground station in South Africa received the all-important signal indicating that EarthCARE is safely in orbit around Earth.

With the climate crisis increasingly tightening its grip, ESA’s Earth Cloud Aerosol and Radiation Explorer, or EarthCARE for short, will provide crucial information to shed new light on the complex interactions between clouds, aerosols and radiation within Earth’s atmosphere.

This exciting new mission is a joint venture between ESA and the Japan Aerospace Exploration Agency (JAXA) and was designed and built by a consortium of more than 75 companies under Airbus as the prime contractor.

ESA’s Director of Earth Observation Programmes, Simonetta Cheli, said, “EarthCARE is the most complex of ESA’s research missions to date. Its development, and now launch, is thanks to close cooperation with our JAXA partners, who contributed the satellite’s cloud profiling radar instrument, and all of the space industry teams involved. The mission comes at a critical time when advancing our scientific knowledge is more important than ever to understand and act on climate change, and we very much look forward to receiving its first data.”

JAXA’s Project Manager for the cloud profiling radar, Eiichi Tomita, added, “Increasing the accuracy of global climate models by using EarthCARE data will allow us to better predict the future climate and therefore take necessary mitigation measures. JAXA provided the cloud profiling radar – the world’s first radar that can measure the velocity of upward and downward flow within clouds. We are expecting these EarthCARE data products to be remarkable.”

The EarthCARE satellite is now being controlled from ESA’s European Space Operations Centre in Darmstadt, Germany. Controllers will spend the next few months carefully checking and calibrating the mission as part of the commissioning phase.

About the European Space Agency 

The European Space Agency (ESA) provides Europe’s gateway to space. 

ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world 

ESA has 22 Member States: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Latvia, Lithuania, Slovakia and Slovenia are Associate Members. 

ESA has established formal cooperation with four Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement. 

By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country. It is working in particular with the EU on implementing the Galileo and Copernicus programmes as well as with Eumetsat for the development of meteorological missions.
