If they get all three wheels on the left side onto the top of home plate could they drive mostly parallel to to the edge until the right side wheels are on top too?

Unfortunately, rover is increasingly pushed to the right. This tendency worried me.

The terrain on the right side of the rover is more benign: lower slopes and smoother. Unfortunately it seems that in spite of moving to a better surface does not help making much progress uphill.

Yes, probably that would do, but it would take several drives and very likely the rover would slip downhill adding difficulties to an already complex situation. At this time I do not think it is a good idea to change the rover heading so drastically that would affect an emergency drive downhill. As it often happens, many good ideas have to be discarded to maintain the rover safe.

Wow!
I was coming here to add a post about the latest "bump" which happened yestersol (1772) but this navcam shot, if it's trully a cleaning event, is a great gift. Thanks Santa!

<searching for a previous navcam shot...>

Doug blowing out those 30 candles may have made a difference after all! laugh.gif
Animation here....and detail here

Hopefully this is not just a trick of the light and there has been some improvement to power levels. smile.gif

Yay!

Definitely not a trick of light since you can see dust streaks on the hinged solar panel. The cells closer to pancam seem a lot cleaner! This looks like great news smile.gif

You see? Gluing on a mince-pie, glass of sherry and a "Dear Santa" letter onto the side of the Rover is *much* more effective than adding silly wipers on the panel. This way Spirit is guaranteed to get a good cleaning every Xmas!
Seriously, if that is right, well spotted guys!

Back to the bump, which I perceive as intentionally downward...
Does this mean the attempts to get back on top at this spot are over?

Is it my imagination or does the dust look a bit thicker on the rear (I think?) panels, to the right of the image? If so I hope it's not enough to negate the power gain from the cleaner panels unsure.gif

Those two pics in Tesheiners posting make it pretty evident that a cleaning event has taken place. Did we ever have such a partial cleaning before, with dust streaks on the panels? Numbers, numbers please!

Well spotted OWW!

The rear hinge and a wire are partially covered by darker dust. And the... huh... stick, has a dark streak blink.gif
