Based on the imaging plan I would say East. 01784::p0665::03::10::0::0::10::0::20::navcam_5x1_az_108_3_bpp 01784::p0765::01::10::0::0::10::0::20::navcam_5x1_az_288_1_bpp There is a potential passage about 7m to the east. It was seen on Sol 768 IIRC, it might be traversable. We'll see.

What distance can she rove on each sol with the current watt/hour numbers ? Has the MER team got a plan to find a ramp and drive on HP? -------------------- "It`s one small step for a man.

All very good questions, for which I have no answers yet. There will be a pow-wow today discussing these issues but I will be on a MER-B shift today so I am not sure I will be able to attend. I will let you know if I hear anything.

New Navcam pan for Sol 1784. Here once again is my crude stitch (QuickTime 3.6 MB)

And a panorama for quick browse.
The ground sure looks like its tilted towards the plains... watch your step -------------------- |

I think that we have less dust than before. What do you think? |

In some places less, in some places more - I think we're seeing redistribution rather than clearance here.

But a good sign nonetheless. Now if we get a few more "redistribution" events it might redistribute some of the dust to the ground.

Oh yeah. We're at 'cleaning time' in terms of season - we're less than 20m from the last SIGNIFICANT cleaning event location. All the signs are positive.

I noticed a partial deck pan from sol 1783, so I thought I would do a quick stitch.
CODE Sol Seq.Ver ETH ESF EDN EFF ERP Tot Description ----- -------- --- --- --- --- --- ---- ----------- 01783 p1914.02 5 0 0 5 0 10 navcam_5x1_deck_LEYE_3bpp The result is a bit distorted for some reason, but interesting to study. It appears that there are several populations of dust, silt, and sand grains on the deck. I obviously cannot see the grains themselves, but I am hypothesizing (speculating) from the colors and patterns I see. We observe light, medium, and dark colored patches of sediment on the deck. There clearly has been a lot of moving and sorting of grains on the rover's horizontal surfaces over the past months. The wind-oriented fingers of sediment flowing around minor obstructions such as the bolt heads to the left of the mast are scary. That is some pretty heavy buildup, and without the aid of saltation, some of it might be pretty difficult to remove in typical "dust cleaning events." Looking at this scene, I can't help but wonder if this WH3 location, below the very edge of HP has allowed larger saltating grains hopping across Home Plate's surface, to hop onto our desperate rover as it clung to its life-giving, north-facing slope all winter and into this spring. I guess I am not certain what the prevailing wind direction is here as the seasons change, so I probably shouldn't speculate about such things. I suppose I should edit this post to note that the areas of the heaviest buildups are mostly away from the solar panels. -------------------- ...Tom

We did not have much of a choice, unfortunately. :-( It is possible that the orientation of the rover could have caused additional deposition of particles, but no matter where we could have parked, the orientation of the rover would not have been significantly different relative to the direction of the prevailing winds. In addition, the rover deck was for a good portion at a higher elevation than HP. If saltation was really the process in play here, I am misunderstanding the scale of the height and length of the hops.

The Bonestell pan is finally all down! here is my version.
And a Mars bar to the first person to spot what is missing from this pan that is in (I think) every other large 360 degree pan from the rovers. James -------------------- |
