A team of British scientists is trying to restart a drilling mission through the Antarctic ice shelf to reach a prehistoric lake.

It is hoped that it will reveal evidence of life that could be found elsewhere in the solar system.

Drilling down deep into the earth through a lake, they are faced with small time windows before the bore-hole refreezes to an unusable size, ultimately sealing the lake off again.
