Frosted Impact Crater in Late Northern Winter

Like Earth, Mars has concentrations of water ice at both poles. Because Mars is so much colder, however, the seasonal ice that gets deposited at high latitudes in the winter and is removed in the spring (generally analogous to winter-time snow on Earth) is actually carbon-dioxide ice. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)

Looking for Changes in Dust Drifts West of Alba Mons

This image was intended to search for surface changes after three Mars years in a dust-covered region west of the Alba Mons volcano. It was acquired at almost the exact same season as another image in 2007, and the illumination and viewing angles are very similar. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)

Lava Against an Impact Crater in Elysium Planitia

This image shows lava crumpled against the upstream side of an impact crater. In places where we see smaller ridges in the lava, they have steep faces that retain less dust and look rocky. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)
