Exploratour - Water on Mars
Leave the tour and look at the labeled map of Mars.
Martian Channels
This is a close-up image of a long straight Martian channel. Scientists do not know if the channel carried water or not. Scientists also do not know which way the water flowed, if water flowed at all. Scientists have to prove these things if they hope to understand how the water cycle works on Mars.The picture shows a canyon of Nanedi
Vallis, one of the Martian valley systems cutting through
cratered plains in the Xanthe Terra region of Mars. You can find Xanthe Terra in the big labeled map of Mars at the bottom of this page.
