Abstract
Abstract The surface of Europa may hold biochemical evidence of life in the ocean below. Plans for the analysis and return of samples containing organics from the surface of Europa are well developed; for example, the Ice Clipper Mission. Planetary protection issues must be considered in planning for a returned sample from Europa. Previous studies for sample return from Mars and the return of comet dust by the Stardust mission provide a basis for comparison for a Europa sample return mission. The extreme radiation environment on the surface of Europa would kill even the most radiation resistant microorganism present to depths of many tens of meters in the ice. T...
