According to foreign media reports, NASA's "curious number" rover on Mars to an alpine way to find more evidence that the red planet was a place to live - mdash; & mdash; number Microbes may be present on Mars a billion years ago. "Curiosity" rover in this area found the sample revealed that this area there are a variety of minerals, rock samples of mineral chemical composition is also different.

These different rock samples also help scientists map out changes in the chemical composition of the groundwater-rock interaction as a function of time. Since water is a necessary condition for the existence of life, if there was water on Mars, which means that in the past may be suitable for life in the environment. NASA Mars Science Laboratory scientist Joy Crisp said: "We (the curious rover) in the process of moving to find a different livable environment. & Rdquo;


"The Curiosity" rover landed in the Gale crater area of ​​Mars four years ago and found something similar to organic matter. Curious, the current nine miles, is climbing Mount Sharp, about 5500 meters above the surface of Mars.


Specifically, the "curious number" found for the first time on Mars, boron-containing minerals, which had never been found in the boron on Mars. Boron is a mineral soluble in water. In addition, the "curious number" also found in the rock cracks in the chemical substances. NASA scientists believe that both mineral and elemental content have interacted with surface water and groundwater.
