Mars Map Mystery Studying at the Mars campus, Eagle, Robyn and Hawk stumble upon a mysterious old map that seems to reveal a network of Martian canals built by some ancient civilization. If they can find them it would be the discovery of the century, not to mention an A+ presentation in class. Their search takes them on a wild trek across the red planet, where they brave a massive storm, tornadoes, dust devils, and even an encounter with Sojourner, the original Mars rover – but no sign of any “canals”… only to discover that the map is a fraud, and the idea of Martian canals was debunked long ago. Eagle is downcast until he realizes that their search has yielded a discovery just as interesting: a dry river delta, evidence of Mars’ watery past. No aliens, but it still a nifty presentation!
