Slurries Of Mud May Have Flowed In Martian Gullies

Slurries Of Mud May Have Flowed In Martian Gullies. The Australia Broadcasting Corporation (11/2, Catchpole) reports, “Martian water most likely flowed as slurries of mud rather than trickling streams, according to a recent NASA report.” Jennifer Heldmann of the Ames Research Center analyzed pictures of the Terra Sirenum and the Centauri Montes regions of Mars, comparing them to similar patches of gully deposits in the Atacama Desert in South America. “This data revealed the light tone was caused by the difference in the size of the particles in the mudflows compared to the coarser-grained surrounding terrain.” Scientists “say this indicates the best way to look for water on Mars is not to look for differences in the composition of the sediments, but in the size of the particles.
