The University of Georgia's Richard B. Russell Library is celebrating the 50th anniversary of the moon landing with an exhibit of rare items collected during the Apollo 11 mission. The collection includes the Georgia state flag, which traveled to the moon on the Apollo 11 spacecraft. Also on view: part of a spaceship. On Tuesday, visitors can see the star of the show — which is a rock. Specifically, it's a moon rock, which was given to the state of Georgia in 1972.
