Blog Post Image: What Lies Beneath: NASA Antarctic Sub Goes Subglacial

A student tests the Micro-Submersible Lake Exploration Device used to access Antarctic subglacial Lake Whillans. About the size and shape of a baseball bat, the robotic sub is equipped with hydrological chemical sensors and a high-resolution imaging system. The instruments and cameras were used to characterize the geology, hydrology and chemical characteristics of the lake. JPL researcher Alberto Behar supervised a team of students from Arizona State University, Tempe, in designing, developing, testing and operating the sub. Image credit: NASA/JPL-Caltech
