Drilling was due to begin at the weekend but one of the boilers used to melt snow failed to start up. New parts have been ordered but drilling is not likely to resume before December 21.
Professor Martin Siegert, principal investigator of the Lake Ellsworth team, explains more:
Scientists are to begin drilling through 3km of ice to reach an Antarctic lake that has been untouched for hundreds of thousands of years.
A team of British scientists is set to start drilling deep into an Antarctic ice sheet in the hope of finding life in an ancient lake.
