The Triposo guide to Mars is available as a download guide within the iOS Triposo App. The Triposo guide covers different sections, including practical information. The exploring nature has most articles - there are huge mountains, deep valleys and giant plains. We've listed some of the remains of earlier mission to Mars under sightseeing, but as we have no exact coordinates it may be quite hard to find these places.
There's very little user generated content, which makes it hard to have a guide that's as good as the guides to planet earth' most popular destinations.
