Technicians prepare to launch a giant research balloon from Antarctica during a prior season. Early this month they will launch a similar balloon carrying Super-Tiger, a set of instruments designed to catch and analyze the heaviest cosmic rays -- the nuclei of atoms heavier than iron blasted into space by exploding stars. The balloon should stay aloft for weeks, circling around Antarctica while it probes the universe. [NASA/BPO]
