Rockets to the moon; the oldest known organic molecules on earth; neuronal processes that lead to producing sound; profile of Lonnie Thompson

A team of NASA scientists who will smash two SUV-sized rockets onto the lunar surface and unleash a debris cloud to study data that could provide the key to understanding how to build a permanent base on the moon; microbiologist Jack Griffith, who made a phenomenal discovery - the oldest known organic molecules on earth; research on an Australian songbird called the zebra finch, shedding light on the neuronal processes that lead from understanding sounds to producing them; and a profile of climate scientist Lonnie Thompson, aka Tropical Ice Core Man.
