Ice worlds like Europa and Enceladus are intriguing targets for the search for life because they have oceans of water. But that water is locked under a thick shell of ice that could be kilometers deep. Researchers are testing new technologies to drill through the ice, such as the Search for Life Using Submersible Head (SLUSH) probe. This probe is heated to melt through the ice but has a rotating drill to speed up the descent. It was recently tested on Devon Island.
