CryoSat taken to new heights for ice science

Ice plays a critical role in keeping Earth's climate cool, but our rapidly warming world is taking its toll and ice is in general decline. For more than 10 years, ESA's CryoSat has been returning critical information on how ...

CryoSat maps ice shelf on the move

It is now almost 10 years since ESA's CryoSat was launched. Throughout its decade in orbit, this novel satellite, which carries a radar altimeter to measure changes in the height of the world's ice, has returned a wealth ...

Image: Antarctica detailed in 3-D

Unfortunately ice is a hot topic when it comes to understanding and monitoring how this fragile component of the Earth system is being affected by climate change. Scientists, therefore, go to great lengths to study changes ...

Proba-V captures Bolivia's Salar de Uyuni, the world's largest salt plain – its 10 500 sq km make it larger than some countries.

Probing Greenland's ice sheet for future satellites

With a helicopter the sole feature on the vast expanse of ice and her only way back to warmth and safety, polar scientist Anna Hogg must have thought, "What on Earth am I doing out here?" as she set to taking ice samples.

Sentinel-3A fully tanked

With the launch of Sentinel-3A confirmed for 16 February, preparations for liftoff are charging full speed ahead. The tricky task of fuelling the satellite has now been ticked off the 'to do list' and the propulsion team ...

The moment a team of technicians, gowned like hospital surgeons, wraps the Sentinel-3A radar altimeter in multilayer insulation to protect it from the temperature extremes found in Earth orbit.

CryoSat maps largest-ever flood beneath Antarctica

(Phys.org) —ESA's CryoSat satellite has found a vast crater in Antarctica's icy surface. Scientists believe the crater was left behind when a lake lying under about 3 km of ice suddenly drained.
