Greenland wildfire

10.8.2017 15:51  
Greenland is usually associated with ice and snow, but over the last couple of weeks a wildfire, captured here by the Copernicus Sentinel-2A satellite, has been raging in the western part of the country

Does loss lead to instability?

2.8.2017 13:46  

Thanks to the satellite era, we recently witnessed the birth of one of the biggest icebergs on record. While the breakup of Antarctica’s Larsen C ice shelf hit the headlines around the world, this dramatic event also presents scientists with a unique opportunity to learn more about ice-sheet stability.

Taking farming into the space age

1.8.2017 13:00  

Humans started to cultivate land around 10 000 years ago, so we must be pretty good at it by now. However, environmental concerns, sustainability, quotas, subsidies and paperwork make farming more challenging than ever. Satellites offer a solution to many of these problems, but how does the ordinary farmer tap into their potential?

Sentinel satellite captures birth of behemoth iceberg

12.7.2017 12:50  

Over the last few months, a chunk of Antarctica’s Larsen C ice shelf has been hanging on precariously as a deep crack cut across the ice. Witnessed by the Copernicus Sentinel-1mission, a lump of ice more than twice the size of Luxembourg has now broken off, spawning one of the largest icebergs on record and changing the outline of the Antarctic Peninsula forever.

Giant iceberg in the making

5.7.2017 9:36  

All eyes are on Antarctica’s Larsen C ice shelf as a deep crack continues to cut across the ice, leaving a huge chunk clinging on. When it eventually gives way, one of the largest icebergs on record will be set adrift.  Even before the inevitable happens, ESA’s CryoSat mission can reveal some of the future berg’s vital statistics.
