"The Gale Crater on Mars was chosen as a target site for Curiosity, as the region has shown evidence of once containing water, that property vital for life everywhere. Previous work with NASA’s Mars Reconnaissance Orbiter has identified clay minerals in the area, which would form with adequate liquid water, although this is thought to have occurred more than 3 billion years ago.

At Utrecht University in the Netherlands, NASA is attempting to recreate certain geophysical rock formations and patterns found on Mars in a purpose-built 7 x 12m tank designed to investigate how rivers form. The Eurotank, a project built by the geophysical department of Utrecht University, is a large tank that can be positioned in all three axes. It is filled with sediment, positioned in a downstream angle, and water flowed through the sediment. Investigations are then made into the movement of the particles with the flow of water. Different soils with different grain sizes will have different deposition patterns and, using the tank, scientists can study the behaviour of various sediment materials.

Some of the surface features on Mars resemble the meanders and patterns created by rivers. NASA is using the Eurotank to simulate a possible set of circumstances that would create these types of surface features, with the hypothesis that in the distant past they were created by water.
