The Cassini spacecraft has made its lowest pass yet over the south pole of Enceladus, an active moon of Saturn which may harbour a liquid water ocean.
The flyby, at an altitude of 74km (46mi), allowed Cassini to "taste" the jets of ice and water vapour that gush from the moon's polar region.

The spacecraft's closest approach took place at 1930 GMT on Tuesday.
