For well over three years, planetary scientist Ellen Stofan has worked directly with NASA Administrator Charles Bolden to help coordinate and expand the myriad science efforts by the agency. We talk with her as she ends this remarkable tenure. Emily Lakdawalla says don’t miss Hidden Figures. Bill Nye checks in from Japan with a tribute to the late Apollo moonwalker Gene Cernan.
