TEXAS, KOMPAS.com - Machines NASA's Mars rover, Curiosity, again presenting new information. With the Russian-made equipment, Dynamic Albedo of neutrons (AND), Curiosity found evidence of hydrogen on Mars that could be indicative of water.
Detection of the existence of hydrogen is obtained in the exploration of Curiosity in very dry areas on Mars. In exploration, the machine detects most of the hydrogen is in the form of water molecules (H2O), which binds to minerals.
"We see the signal variation along the trajectory of the landing to the Gulf of Yellowknife," said Maxim Litvak of the Space Research Institute, Moscow is also AND Deputy Principal Investigator.
"More water is detected in Yellowknife Bay than the previous location. Nevertheless, Yellowknife Bay we also see a significant difference," he added as quoted by Physorg, Monday (18/03/2013).
The research team also explained that they found indications that the process that produces the wet clay (clay) in the Gulf of Yellowknife happen without making a lot of changes in the mix of chemical elements that exist today.
Element composition of the surface rocks were exhumed by Curiosity match the composition of basalt rock. Rock were excavated containing proportions of constituent elements, such as silicon, aluminum, magnesium, and iron-like composition of basalt rock.
"The composition of elements in rocks in Yellowknife is not changed much by changes in mineral," said another member of the research team on this mission, Mariek Schmidt, of Brock University in Canada.
"After cleaning the dust, we got the results of the analysis show that the classification of the rock there is a rock with a composition as basalt rock," he explained.
Before the dust cleared inherent in the rock, investigators got confused because the composition of the dust. Based on the analysis instrument Alpha Particle X-ray Spectrometer (APXS), its elemental composition is less suitable to be categorized as basaltic rocks because there is sulfur.
However, after the dust has cleared the brush Curiosity, APXS see not too much sulfur in the rock. This indicates that the rock has elemental composition similar to basalt rock.
Researchers suspect that the basic rocks in Yellowknife original form when basalt rock shattered into fragments, then suffered displacement and collected back as sediment particles and mineral change when exposed to water.
