In March, NASA’s Curiosity rover rolled across the surface area of ​​Mars called the “Garden City”. This area is criss-crossed with mineral veins that stick out above the surrounding dirt, which makes it an ideal place to study the composition of these minerals.

To this end, the researchers used a curiosity “ChemCam” tool that fires lasers at the facilities and analyzes the sparks they provide, to find that they are made. It turns out that they are quite diverse, with many different chemical ingredients.

It is believed that the veins were formed long ago for a few wet periods in the history of the Red Planet. As the water flowed through cracks in the bedrock, he had dissolved minerals that were deposited when the water dried up again.

In various wet periods, different minerals were deposited -. Explain the diversity that curiosity to find

very mysterious

The analysis was made possible by the modernization that NASA engineers have recently been completed. This is more than three times the number of geochemical samples, the system can recognize that allows a much broader range of substances, to be seen and classified.

“Chemistry in the Garden City would be very mysterious, if we did not have this recalibration,” said Diana Blaney, a member of the Curiosity science team.

Next, a brave rover to go to the higher, younger part of the mountain that is currently exploring – Mount Sharp. Comparing the makeup of rocks in different regions, the researchers should be able to get a better understanding of the complex history of Mars.
