Bering in dire straits

14 March 2019

The Bering Strait is a sea passage that separates Russia and Alaska. It is usually covered with sea ice at this time of year – but as this image captured by the Copernicus Sentinel-1 mission on 7 March 2019 shows, it is virtually ice-free.

Sentinels monitor converging ice cracks

14 March 2019

The Copernicus Sentinel-1 radar mission shows how cracks cutting across Antarctica's Brunt ice shelf are on course to truncate the shelf and release an iceberg about the size of Greater London – it's just a matter of time.

Working towards AI and Earth observation

11 March 2019

Satellites observing and measuring our planet deliver a huge amount of data that not only helps understand how our world is changing, but also benefits society by feeding into a myriad of everyday applications. Taking this to the next level, ESA is exploring how even more could be gained from these valuable data by using artificial intelligence (AI).

New observations for the new economy

08 March 2019

We all listen to weather forecasts and know they rely on satellite data. What may not be so obvious is that many other aspects of our lives depend on robust satellite data, from growing crops to tackling the major issue of climate change.

Proba-V 2018-2019 Antarctica data now available

07 March 2019

For the second consecutive austral summer season (see the 2018 news), Proba-V observed Antarctica and its ongoing changes: observations on the continent's land and sea ice surfaces were performed from 12 November 2018 until 18 February 2019.

EarthCARE mission to improve weather forecasts

06 March 2019

Earth observation satellite data are crucial for generating accurate weather predictions. They provide a global picture of the current state of the atmosphere, which is used as the starting point for creating a forecast. But our knowledge of that current state is limited, partly because satellites have so far not been able to collect much information about clouds, which play a key role in the weather. The ESA/JAXA future mission EarthCARE will provide this information to improve our predictions about the future weather and climate.
