The upper image is a radargram from the European Space Agency's Mars Express orbiter. It shows layered deposits underneath the surface near the north pole. The data suggests that the material between the two whitish lines, or radar traces, is nearly pure water ice. The lower image shows the position on the ground where the spacecraft passed overhead.

Mars Express arrived at Mars in December 2003. Its radar instrument is jointly funded by NASA and the Italian Space Agency.
