A Bozeman fourth grade class won a NASA contest naming two spacecraft that began orbiting the moon on New Year’s Eve and New Year’s Day. The winning names “Ebb” and “Flow” were chosen by NASA among nearly 900 classroom entries. The Spacecraft are part of the Gravity Recovery and Interior Laboratory, or GRAIL. GRAIL is the first planetary mission to carry instruments for education and public outreach. The students of Nina DiMauro’s class at Emily Dickinson Elementary School also get the chance to pick the first images that will be taken by the small cameras on the spacecrafts.
