Study shows how water may have flowed on ancient Mars
NASA scientists have discovered how an intricate martian network of streams, rivers and lakes may have carried water across Mars. Using new three-dimensional data from the Mars Global Surveyor spacecraft and a powerful state-of-the-art computer code that ‘models’ overland water flow, scientists visualized the complex flow of martian water. These data, acquired by the laser altimeter on board the spacecraft, provided highly accurate, three-dimensional topographic views of Mars.
