Drilling into Cryopeg (IMAGE)
Caption
Zac Cooper and Shelly Carpenter begin to drill below the ice tunnel towards the cryopeg and its salty subzero water. Researchers are careful to sterilize their equipment to avoid introducing contamination from above ground. The most stringent of such techniques will be needed to sample for life on other planets.
