Nicolle Zellner (Physics) participated in a NASA-sponsored mission concept study focused on determining whether or not measuring compositions and ages of geological samples in situ was feasible. The concept study focused on missions that would measure samples on the Moon, Mars, and Vesta in order to address questions related to the evolution of each planetary body, as well as the bombardment history of each object specifically and the solar system in general.
