Here's a composite of four frames, enlarged and contrast-adjusted.
The basin is too off-centre to account for the bright hemisphere. Phil -------------------- ... because the Solar System ain't gonna map itself.

The basin is too off-centre to account for the bright hemisphere. Could the reason for the apparent brightness be purely in different terrain roughness? A couple of enhanced color views. While in natural color the higher albedo ice would probably look white, IR/UV filters show the polar regions are more reflective in UV (cleaner ice? CO2 vs water ice?). -------------------- |
