A NASA spacecraft in orbit around the moon has sent back five dozen new images of the lunar surface including a view of the far side with Earth in the distance. Don\'t thank scientists for it. Fourth-graders from Emily Dickinson Elementary School in Bozeman directed the spacecraft to snap pictures as part of a project headed by Sally Ride, the first American woman in space. The images were returned earlier this week. Twin NASA probes entered lunar orbit over the New Year\'s weekend on a mission to study the gravity field. During non-critical parts of the mission, select students get to choose camera targets. The Montana students got first dibs for winning a NASA-sponsored contest that renamed the craft Ebb and Flow.
