ADMIN NOTE: Hi All, a new topic for the discussion of the science from the SAM and Chemin instruments.
There has been a very important amendment to Rule 1.3 which is explained here. Please remember Rule 1.3 at all times when discussing matters in this section. |

Many Mars meteorites contain organics at levels that are very detectable by SAM. Amino acids at 100ppb levels have been reported. There is some controversy over the origin and these might be terrestrial. A high temperature Martian origin seems to be the favored explantion. Levels of reduced carbon in the 1-50 ppm range have also been reported, and this would be easily detected by SAM.
The bottom line is that there is a good chance that SAM will detect traces of organics in the next few months if it hasn't already. IIRC the detection limit for SAM is 1ppb organics. Amino acids in mars meteorite Reduced organic carbon in mars basalts |
