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 diagram in Emily's blog indicates that waste products from SAM are vented. Does anyone know where the vent is located? Is it reachable by the rover scoop? If, say, water vapor were to be vented at night, it would presumably condense into frost and might be collected on top of a sample, perhaps? That's at least an idea for a round-trip, but... There is a hint in The Sample Analysis at Mars Investigation and Instrument Suite, p. 433, where the exhaust vent goes: QUOTE The molecular drag stage is designed to exhaust directly to the Mars ambient surface pressure of 700 to 960 Pa. I'd think, that even if water vapor would be exhausted at night, it would be dispersed finely, especially regarding the slope winds at night, and sublimate soon after sunrise. No way to get significant amounts scooped. |
