Call for dedicated polar Sentinel satellite
24 March 2016
European scientists are worried they could soon lose a vital tool for monitoring Earth's ice fields.
The Cryosat-2 radar spacecraft has transformed studies of the Arctic, the Antarctic and Greenland, but is now operating beyond its design lifetime.
A group of 179 researchers is concerned the ageing mission could die in orbit at any time.
They have urged the European Commission (EC) and the European Space Agency (ESA) to start planning a replacement.
