This article describes a permafrost subglacial lake discovered beneath Antarctica. The lake offers scientists a chance to test their sterile drilling techniques before exploring elsewhere in search of exotic microbes. Techniques that avoid contaminating a drill site with microbes, suggests the author, would prove useful for future drilling into Mars' polar caps in search of life.
