Prof. Paul Sava has been awarded funding from NASA to develop the highest-resolution 3D images ever of what lies in the interior of Mars’ polar ice caps. “Just like on Earth, the ice caps are witnesses of the climate on Mars — it’s a bit like observing tree rings,” said Paul Sava, professor and Green Chair of Exploration Geophysics with the Center for Wave Phenomena at Mines.  In addition to providing valuable insight into Mars’ climate history, the high-resolution images could also be of use to those interested in developing space resources to fuel future exploration of the planet.
