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. |

The discontinuity seems to be:
1. "Organics" was not precisely defined. That's a charged word, obviously. However, they did effectively communicate the fact that complex organic compounds most likely have meteoritic origins till proven otherwise, and even cited the recent Messenger findings on Mercury as an evidence that such compounds are far from uncommon throughout the Solar System. 2. The 'organics' thought to be detected seem to be most likely evolute products from the sample heating (i.e., chloronated methane). Several references to 'single carbon' compounds...well, so is CO2. Judgement call. Bottom line from my perspective: SAM & the other instruments seem to be working well. This was pretty much a first-grab sample from a dune, so not much should be expected given that dunes usually consist of windborne (not necessarily local) material; it's gonna be light stuff no matter what. Now let's see if we find some phyllosilicates... -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
