Solutions to the Mars DVD Codes

The solutions for the secret codes on the Planetary Society DVDs located on the landers of the Spirit and Opportunity Mars Exploration Rovers. Have fun and read only if you've already tried to solve the codes.

Spirit DVD Code Solution

The four images were captured through four different filters: a red filter, a green filter, a blue filter, and an "empty" filter. This is the "L4" or red filter image.Image: NASA / JPL-Caltech / Cornell
