Russian instrument DAN (Dynamic Albedo neutrons), mounted on the Mars rover Curiosity on Mars recorded a non-uniform distribution of groundwater. This was reported by the Institute of Space Research Institute (IKI), Russian Academy of Sciences.
"The participants in the experiment DAN are currently trying to figure out the cause of some wet areas of the Martian surface, which can be called a sort of" oasis "in the Martian desert," - said on Tuesday, a representative of IKI.
He added that since the Curiosity rover’s landing in August 2012 on account of the Russian unit for several hundred measurements of the surface of the Red Planet, made using the neutron probe.
"With the obtained data the researchers were able to study the depth distribution of ground water, which turned out to be non-uniform. In the upper layer of soil mass fraction of water is markedly different from the amount of water, located at a depth of 10-20 cm, "- said the expert.
DAN instrument was commissioned by Russian Space Agency in IKI. In the experiment involved experts NASA Jet Propulsion Laboratory, as well as experts of U.S. universities.
