Curiosity take internal structure of Martian rock: prove that water was present
According to media reports, NASA "curious" Rover found more evidence that the red planet, once the presence of water. The scientists say "a Martian rock cracking curiosity" over the exposed white structures, that contain hydrated minerals in the water, outdated form.。：HIYA：
Last week, "curiosity" carries on the analysis to the Mars rock powder samples drilled after the discovery of important evidence, prove that the red planet once existed drinkable water and suitable for the conditions for life. Now, "curiosity" instrument in the name "Diendina" (Tintina) around the rocks found more hydrated minerals. In addition, the rovers also found that hydrated minerals in "Diendina around", further evidence of the presence of water on mars.
At present, "survey of a regional curiosity" is the Gail crater. The area near the Martian equator, known as the "Yellow Knife bay". Scientists believe that billions of years ago the water once from the crater edge down flow, formation depth can reach up to 3 feet (about 90 cm). These new findings is the use of "curiosity" mast camera infrared imaging capability and a neutron emission to the ground, with the detection of hydrogen instrument. The brightness difference between NIR light can reveal the presence of hydrous minerals. These mineral changes under the action of water.困惑：
California Institute of Technology at - Dr. Condoleezza Rice said: "with the help of the camera, we found that the hydration of signal intensity increase in the narrow texture. These texture through a lot of rocks in this region. These bright texture contain hydrated minerals, different from the clay minerals found in the surrounding rock."
The neutron dynamic Russian-made albedometer to water molecule detection "curiosity" at the foot of soil minerals in the hydrogen. The results show the rest of the quantity of water of Yellow Knife bay had more than "curiosity" after the visit. The neutron dynamic albedo meter program at the Space Research Institute in Moscow, Maksim - Litwack pointed out: "found in the Yellow Knife bay water exist in other regions more than 'curiosity' signs, exploration. The even in Yellow Knife, we also found that great differences exist for signs of water quantity." Lunar and Planetary Science Conference held in Texas, scientists announced their findings.
NASA announced last week, "the discovery of chemical elements important curiosity" analysis of a rock sample, that the planet was once can support life environment. In "curious" date powder samples of rock drilling in sedimentary rocks in an ancient riverbed, scientists found that the sulfur, nitrogen, hydrogen, oxygen, phosphorus, and carbon, some of which are formed an important chemical elements necessary for life. Analysis of the data shows, "Huang Dao Wan curiosity" current exploration may be an ancient river's end, or is an intermittent wetting lake bed, can provide chemical energy and other necessary conditions for microorganisms.头发：
"Curiosity" project scientist John - Negro Leipziger said: "our study shows that Mars once appeared the livable environment, able to support life, there may even be drinkable water." NASA headquarters in Washington's Mars exploration program chief scientist Michael - Meyer pointed out: "one of the basic problems in this task need to answer is whether Mars ever appeared, for the existence of life environment. According to our current understanding of the situation, the answer is yes.":evil:
