On Thursday, the European Space Agency launched a satellite to map out the Earth's ice fields over the north and south poles.
The satellite was launched from the Baikonur Cosmodrome in Kazakhstan.
The mission of CryoSat -2 is to measure the changes in the icesheets covering land and water. Similar missions have been completed over the years to gain a better understanding of climate change, but now scientists are investigating how the thickness of the ice is changing.
There's hope that this 3 year mission will help to predict any future patterns.
