Curiosity rover completed its first phase of work which includes the study of Martian soil and rocks. Specialists performed an analysis of the mineral composition of soil in the chemical laboratory, located on board the rover. "We found out that the mineral composition of Martian soil is very similar to volcanic soils in Hawaii", - the report says NASA.
The study collected on the surface of Mars soil was sieved through a sieve to eliminate particle size which was more than 150 microns. Experts have established that the sample contains two components, such as dust and fine sand.
"All the samples were analyzed at this time confirm our assumption that the deposits in the bottom of the crater Gale held chain of transformations from the" wet "environment to a" dry ". Remains of ancient rocks suggests that once existed on Mars flows of liquid water, and minerals contained in the younger soil layers indicate limited interaction with water, "- said David Bish, a geologist from the University of Indiana.
Bish recalled that the analysis of a piece of rock obtained earlier showed that it consists of individual grains of minerals, including feldspar, pyroxene and olivine.
Curiosity arrived at Mars on August 6. The main purpose of the device, which is an autonomous chemical laboratory, was the search for traces of life on Mars and study its geological history.
