That would be unusual for there to be such a visible contrast in albedo without both solid ground and liquid. I know they enhanced the contrast, but that is usually a pretty good indicator that it is liquid. However, I highly doubt that it's water. On the other hand, it might just be that the surface material is more densely packed in the whiter areas. I know that in most active remote sensing they use a fairly high energy beam that often penetrates lower density surface features a bit before getting reflected back. That might make it appear to be a different material.

I'd be interested to see remote images of it in the visible wavelengths to take better guesses at this, but then I guess that kind of thing is unnecessary with the probe and all
