Sulfate minerals and organic compounds on Mars
Strong evidence for evaporitic sulfate minerals such as gypsum and jarosite has recently been found on Mars. Although organic molecules are often codeposited with terrestrial evaporitic minerals, there have been no systematic investigations of organic components in sulfate minerals. We report here the detection of organic material, including amino acids and their amine degradation products, in ...
متن کاملMars Organic Detector III: A Versatile Instrument for Detection of Bio-organic Signatures on Mars
Recent advances in the development of microfabricated lab-on-a-chip analysis systems have enhanced the feasibility and capabilities of in situ chemical and biochemical analyzers. While a wide variety of bio-organic molecules can be probed, we have focused our initial studies on the development of an amino acid analyzer with the hypothesis that extraterrestrial life would be based on homochiral ...
متن کاملLife on Mars?
Usually it takes a juicy sex scandal, a military invasion, or an airliner crash to get a story on page one of the newspapers two days in a row. But science reporters across the United States managed this feat in early August, when NASA scientists announced that they’d found “compelling evidence” of fossilized life from Mars. The story broke when a trade paper, Space News, nonchalantly published...
متن کاملSulfate Minerals: A Problem for the Detection of Organic Compounds on Mars?
The search for in situ organic matter on Mars involves encounters with minerals and requires an understanding of their influence on lander and rover experiments. Inorganic host materials can be helpful by aiding the preservation of organic compounds or unhelpful by causing the destruction of organic matter during thermal extraction steps. Perchlorates are recognized as confounding minerals for ...
متن کاملSearch for life on Mars.
A multi-user integrated suite of instruments designed to optimize the search for evidence of life on Mars is described. The package includes: -Surface inspection and surface environment analysis to identify the potential Mars landing sites, to inspect the surface geology and mineralogy, to search for visible surficial microbial macrofossils, to study the surface radiation budget and surface oxi...
