Looks like the Sol 12 images are coming down

Hmm, it's a problem that the door not fully opened. Looks like they need first some cleaning movements with the scoop to be able to open the adjacent door then (if it's feasible at all).

The partially open door hasn't been a problem at all - there's load of material in and around the mesh, which means the oven will have got a sample. The opening of the next door will almost certainly flick the soil out of the way for the next sample.
Using the arm to clear soil from around the TEGA inlets is a bit like clearing dust from the MER solar arrays with the RAT. Wrong tool to do a bad job. Doug |

So the scoop that got dumped came from the dig to the right of the original dig?
That's quite a mess on the ovens, I hope the doors on the adjacent oven can clear it without contamination of the later samples by soil falling back in, I'm sure they've thought of these things. I didn't realize they'd be dumping that much on the oven! Kung -------------------- |

Seems to me they needed a narrower scoop.

The partially opened door has clearly resulted in a less than ideal post-dump situation. I guess we will have to wait for the next press conference to see whether that much spillage will be considered a problem for either getting the doors fully open (the left one shouldn't be a problem) or for dirt from the first sample falling into the hopper and messing up the results. Perhaps they will decide to skip that chamber and only use it as a last resort if they require that many samples.

I suspect the soil does not flow into the funnel at all, and the soil all sticks together and slides out in one lump.

QUOTE (djellison @ Jun 7 2008, 05:17 PM) But then it would take 12 months to dig a good trench Doug The trench will only be as deep as the topsoil, and that seems about 5 cm. A narrow tench is also a good trench. Seems to me the scoop is four times as wide as the oven doors which makes no sense to me. Surly the accuracy of the RA can deliver soil to any 1 cm spot it can reach ? |
