See some animations from NASA's Mercury MESSENGER mission on the official MESSENGER website: Mercury MESSENGER animations.

Some of the sights seen by the space missions to Mars are just amazing, and NASA have turned them into animations based on what the space missions have seen. For example, in this simulation you can fly into the great Valles Marineris, the deepest canyon on Mars, which is over 4,000 kilometres long and up to ten kilometres deep – much, much bigger than the Grand Canyon!

Fly through Mars' great valley.

The Mars Exploration Rover Opportunity is, right now, driving into a huge 800-metre wide crater called Victoria to explore it. Based on real observations made by Opportunity and the Mars Reconnaissance Orbiter high above Mars, this animation takes you flying high over the crater, before swooping down past Opportunity and into Victoria, rushing low over the sand dunes that lie in the crater floor: Victoria Crater.

You can also see dust devils racing across the Martian surface.
