North South Polar's Alberto Behar, an electrical engineer at the NASA Jet Propulsion Laboratory, left, and Mindy Simonson, a Joint POW/MIA Accounting Command (JPAC) anthropologist, watch the image on the screen transmitted from a subsurface camera as Behar lowers it into the bore hole on a glacier near Koge Bay, Greenland, Aug. 9, 2013. Behar built an improved model from the camera he fabricated for the 2012 mission. This camera provides a 360-degree vantage point to the expedition team from inside the hole.
