Move over, James Cameron. Researchers have created the first 3-D subsurface pictures of Mars’ northern icecap — and they’re using these images to solve a 40-year-old Martian puzzle.
The puzzle centered around Chasma Boreale, an ice canyon in the northern icecap that is comparable in size to the Grand Canyon, and the spiral troughs that extend in a pinwheel-fashion from the icecap’s center. How each of these features formed has long mystified researchers.
