The new, three-dimensional map using 358 radar observations provides a cross-sectional view of the north-polar layered deposits. 'The radar has been giving us spectacular results,' said Jeffrey Plaut of JPL, a member of the science team for the Shallow Radar instrument. 'We have mapped continuous underground layers in three dimensions across a vast area.'"
