Europe is facing an intense heatwave, with record temperatures and several cities under red alert. On 23 June, France recorded its hottest June day ever.

This image was captured the same day by the Copernicus Sentinel-3 satellite, which measures land surface temperature from space.

Unlike air temperature, land surface temperature shows how hot the ground itself becomes, often much higher as rock and asphalt absorb heat throughout the day.

Sentinel-3 uses thermal sensors to monitor Earth’s land, oceans, ice, and atmosphere, supporting everything from weather response to long-term climate monitoring.

The European Space Agency’s EarthCARE satellite was developed to make a unique set of simultaneous measurements that shed new light on the role that clouds and aerosols play in regulating Earth’s climate.

Now, in a remarkable example of a research mission delivering direct practical benefits, global observations from the satellite’s cloud profiling radar are being used operationally by the European Centre for Medium-Range Weather Forecasts to improve daily weather forecasts – this landmark achievement marks the first time that cloud radar data from space have been assimilated into a global weather forecasting system.

At 15:24 CEST on 15 June 2026, a faint blue glow in space was switched off for the last time. After powering BepiColombo's eight-year journey across the inner Solar System, the spacecraft's solar electric propulsion (SEP) system completed its final thrust arc, marking the end of BepiColombo’s long cruise phase and the beginning of its arrival at Mercury.
