also released significant carbon dioxide, oxygen and sulfur compounds when heated. Glavin notes that SAM has the ability to perform another kind of experiment to address the question of whether organic molecules are present in the Martian samples. So a scoop of this stuff is basically a microscopic Mars rock collection said Leshin. Upon exposure to temperature the Thermex sheet instantaneously and permanently changes color. The intensity of that color is directly related to the temperature it was exposed to, allowing Thermex to spot high or low temperature zones. "If you mix many grains of it together, you probably have an accurate picture of typical Martian crust. Instead, it is likely that they formed during the high-temperature experiments, when the heat decomposed perchlorates in the Rocknest samples, releasing oxygen and chlorine that then reacted with terrestrial organics already present in the SAM instrument. By learning about it in any one place you're learning about the entire planet.". "One of the most exciting results from this very first solid sample ingested by Curiosity is the high percentage of water in the soil said Laurie Leshin, lead author of one paper and dean of the School Science at Rensselaer Polytechnic Institute. Researchers fed portions of the fifth scoop into SAM. A related paper, published in the Journal of Geophysical Research-Planets, details the findings of perchlorates and other chlorine-bearing compounds in the Rocknest sample. "By combining analyses of water and other volatiles from SAM with mineralogical, chemical and geological data from Curiosity's other instruments, we have the most comprehensive information ever obtained on Martian surface fines.

Baking the sample also revealed a compound containing chlorine and oxygen, likely chlorate or perchlorate, previously found near the north pole on Mars. These data greatly advance our understanding surface processes and the action of water on Mars.". 6, 2012, charged with answering the question: "Could Mars have once harbored life?" To do that, Curiosity is the first rover on Mars to carry equipment for gathering and processing samples of rock and soil. Home, products, example of color enhanced image generated on Thermex paper. In addition to determining the amount of the major gases released, SAM also analyzed ratios 3d printing medical essay of isotopes of hydrogen and carbon in the released water and carbon dioxide. "The isotopic ratios, including hydrogen-to-deuterium ratios and carbon isotopes, tend to support the idea that as the dust is moving around the planet, it's reacting with some of the gases from the atmosphere Leshin said. "Mars has kind of a global layer, a layer of surface soil that has been mixed and distributed by frequent dust storms. Finding such compounds at Curiosity's equatorial site suggests they could be distributed more globally.
The first scoop of soil analyzed by the analytical suite in the belly of nasa's Curiosity rover reveals that fine materials on the surface of the planet contain several percent water by weight.
