Beijing time on September 29, according to the BBC website (BBC) reported that NASA’s Curiosity rover recently drilled since May under the first full depth of rock drilling. In a region is called the “Pahrump Hills” of Curiosity using its drilling tools in a light-colored flat rock surface drill a deep hole.
Curiosity been previously drilled and powder samples collected three times obtained, which was fed into its onboard small analytical laboratory for analysis. The latest analysis of the drilling probably will allow scientists to understand the composition of sedimentary rocks in front.
Sharp car rover is currently traveling near the foothills, which is a city located inside Gale Crater, up to 5000 m peaks. The researchers hope to understand the chemical composition of its rocky foothills, can reveal more details about the historic environment of Mars clues. At present, the evidence of this car weight one ton rover discovery already proven in billions of years ago, lakes and rivers once existed on Mars. Scientists believe that in the ancient Martian environment could support microbial survival perhaps – if they really ever existed then.
After arriving on Mars in the past full year, most of the time Curiosity is in moving forward, hoping to arrive as quickly as possible near the Sharp Mountain, where there is good scientific investigation it pre-selected destinations. Also conducted before Wednesday’s test drilling once the drilling time is on Sunday, aims to test the stability of the device. Drilling a borehole depth of 6 cm of powder samples can be collected inside the rock, the robotic arm will be placed in collection boxes. After screening, part of the sample will be poured into the cabin Curiosity is equipped with analysis.
Curiosity overwhelmed study group hopes to drill sample analysis results will be displayed which has a high silicon content, which is the signal results in recent weeks to other nearby rocks observed spectral display. If this result confirmed that the deposits will further demonstrate this large amount of water in the case of the presence of the formation. After spending two years on Mars, NASA said Curiosity has arrived at a critical period.
After a long trek, Curiosity began to leave their Gale Crater landing pit bottom area, and gradually close a program called “Maury formation” (Murray Formation) geological units. And it is curious number Pahrump Regional geological contact zone for the first time in this sample. This area may constitute a Sharp Mountain foothills formations.
In the next few months time (more likely to be a few years), along with the curious number continues to climb the mountain Sharp, Curiosity will be exposed to more and more young successive strata. Eventually, Curiosity will find a range of phase transformation began rock, where the rock represents a gradual transition from the ancient Mars warm and humid climate is cold and dry climate change advanced.
