Venus Express orbit 1749
A quick and dirty animation of images obtained by the Venus Express spacecraft. The images were obtained during orbit 1749 (one of the the so-called "VEX Terminator Observations").
For more on creating these animations from Venus Express data, visit unmannedspaceflight.com.
The animation is available both on Youtube and as an animated gif (>11MB).
A "cookbook" on creating such animations is available for download from ESA's Planetary Science Archive. (PDF)
