Ant's pan shows there are some small drifts slightly northwest of the current position. Possibly big enough for the sampling tests.

Wondering if they may want to get closer to Glenelg before they scoop soil. A vantage point that would allow them to do remote sensing with cameras and CHEMCAM while SAM and CHEMIN process the soil samples.
That would also allow them to do planning for the first sampling campaign at Glenelg. Craig |

I seem to remember that the plan was to land Mars Pathfinder in an outwash / alluvial area but I don't remember Pathfinder / Sojourner detecting any waterborne sediments except to note that the rocks were sightly tilted in direction. Viking 1 was also targeted to an outflow channel area (where it was thought at the time that there may be a remnant water table near enough to the surface to support microbial life). Unfortunately, these locations have been dry for megayears, and the rocks in the area were washed in from a great variety of locations, making it nearly impossible to judge their geologic context. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Your options basically are 'SAM may or may not have detected methane'. Isn't that fairly obvious? If some startling revelation were found, they would have a press conference about it when they were confident in the results. If there were something up with SAM they would ( as with REMS ) let us know. No news isn't bad news or good news. True; it is hard to make a guess based on no results so please take what I say below with a grain of salt. As far as the methane results, I think there are 3 possible outcomes: no methane, methane detected, or an instrument problem. I would think no-methane would be the most likely outcome, but in that case I would think that the team would have reported these results. That suggests (and only suggests) the other intriguing possibilities. My guess is that methane was detected but its source cannot be positively identified yet. Remember that when SAM was first started, the turbomolecular pump shut down due to high current draw and very high methane readings were recorded. As you know this was caused by Florida air trapped in the TLS. I suspect the team is being very cautious this time, and they may be working to concentrate the Martian air....but I wish they would give us some preliminary results. Sorry to bother everyone with these details, but it seems to me, at least, that the methane results could be very significant, i.e. whether the methane has a biological origin or not. |

Wondering if they may want to get closer to Glenelg before they scoop soil. Craig I wonder if the most interesting soil to scoop would be the cementing matrix that had eroded off some exposed conglomerate. Maybe they could pick up some carbonates. Then again it might be a heterogeneous mix of lots of different minerals; that might be hard to sort out in ChemMin. I am surprised that they did not do a ChemCam raster scan of Hottah. Maybe they could get have gotten lucky and flashed off some of the cementing mineral. |

Hi all
I think there may be something shiny behind Curiosity as there is a bright spot in about the same spot in these left and right navcam images. Roy NRA_401937086EDR_F0042956NCAM00435M_ NLA_401937086EDR_F0042956NCAM00435M_ |

I think there may be something shiny behind Curiosity as there is a bright spot in about the same spot in these left and right navcam images. Good catch. That's sol 50. There was an even brighter one back on sol 38. Bits of some part of MSL's EDL? Either that or the ground is sparkling at us. |

Wow, good eye, Roy! A bit of specular reflection.
Edit: here are the direct links to make it easier: http://mars.jpl.nasa.gov/msl-raw-images/pr...NCAM00435M_.JPG http://mars.jpl.nasa.gov/msl-raw-images/pr...NCAM00435M_.JPG How many pixels wide would be useful? Is 3600 enough? 7200? Double the resolution of your original would be nice, like you used on the closeup. Unless filesize is too large.
