Mars has never given up any of its secrets without a fight. Looks like this time is no different.
Got to feel sorry for all the TEGA team; they're obviously working unbelievably hard on this, and Mars just keeps laughing and kicking dirt in their faces. They must be feeling a combination of frustrated/angry/rotten right now. If any of you are reading this, keep going guys, we're behind you and thinking of you. -------------------- |

Nothing comes easy....
Trying to operate a delicate sample delivery remotely... frankly I am amazed at the progress made so far.... All you folks on the Phoenix team have my utmost admiration. Wondering if the sample material cold welded to the scoop due to the early morning temps? I look at that instrument deck and cannot imagine how cold all the outer surfaces must be.... Craig |

1) hold the scoop so that material should fall out.
2) take dump image 2) turn on the rasp (BBBBRRRATTTTTT!!) 3) take post dump image cheers -------------------- CLA CLL

There is a reason they are not going about it in such a straightforward fashion, PDP8E. Remember the delivery to the first TEGA oven.

http://planetary.s3.amazonaws.com/data/pho...9_16B80MDM1.jpg, which was taken at 07:55, which was after the dumping (which happened some time between 07:33 and 07:49). This is a slightly more exposed picture taken at 7:51 and shows a bit more clearly that the >left< side blob of (wonderful icy) material let go but not the middle nor right. Hence door #1 got the best part of the sample! Just bad stinkin' luck! Paul |

What's most annoying is that with sublimation, the sample isn't going to just sit there until something works.

I can also see other good news :
- if the sample adhere in the scoop this is probably ice (at least on Earth, it's what we'd had say) - some get into the oven, so it doesn't stuck on the screen I very confident "we" will make it -------------------- |

The way the soil clumps and adheres suggests a fair bit of water, like it's either wet or was wet and froze again--the RASP generates some heat, no?
Probably not a whole lot of time for idle experiments, but if soil adhering to the back of the scoop comes loose in some hours, would that suggest that its water content is responsible? -------------------- |

So, if this sample is stuck in there, how are they going to get it out in preparation for the next scoop attempt?
