Martin Pomerantz (far right), physicist-leader of the comic ray research project on six weeks field work at Fort Churchill, Canada, this summer, makes a final check of a cosmic ray recording instrument sealed in triple pliofilm insulating bag just before it is released. Dr. Gordon McClure, left, holds on to the launching line. Shadows of the hydrogen-inflated balloons that will lift the instrument to the earth's outer atmosphere, 20 miles up, show on the tent and in front and back of Dr. McClure. The expedition's mobile laboratory, complete with kitchen, bedroom, and bath, is in the center background.
