MARSIS finds the Medusae Fossae Formation to be massive deposits more than 2.5 km thick in places.

Ash, dust, or ice deposits? Dielectric constant measurements hint at ice...

Neat images, but a minor quibble. The image comparing the MARSIS and SHARAD images of the same region show only a single nadir track. It apparently is for the MarsExpress MARSIS image; the MRO SHARAD image gives a sufficiently different surface contour that it must have had a different nadir track.

Nonetheless, great insights into the planet's glacial geology.
