Lake Ellsworth: Drilling effort runs into trouble
A British attempt to search for life in an ancient lake beneath the Antarctic ice-sheet has run into trouble.
The team has reported "a serious problem" with the main boiler used to heat the water that powers a drill.
Work was halted on Saturday in what could prove to be a major blow to the project to investigate sub-glacial Lake Ellsworth.
The aim is to use 90C water to blast a hole through the two-mile-thick ice-sheet to reach the lake waters below.
