In an interesting new discovery, scientists have found that mud flows like lava on Mars! In a study, published in the journal Nature Geoscience, researchers from the Institute of Geophysics of the Czech Academy of Sciences along with scientists from The Open University, found a way of testing how mud reacts on Mars. The Open University has a low-pressure chamber that can reproduce Mars' atmospheric pressure and composition but it's still influenced by the Earth's gravity! It is, in fact, the closest scientists can get to performing experiments on Martian surface. During their experiment, when the chamber was set to a suitable temperature and the mud was poured, it did not freeze immediately but formed an icy crust. The liquid spilled from the cracks and froze. The cone-shaped structures seen on the surface of Mars through satellites could be these 'mud volcanoes', said scientists.
