Spirit Route Map, Small and Large Scales Options

41 meter drive according to the latest update

While the MER team doesn't post their own one, here is a route map based on the driving info provided by the last status report.



I assumed all drives (except the last one) were due east, which is more or less confirmed by the navcam imagery. Note that "east" on this map is about 6º clockwise because the background image is not map-projected.

PD: If the map proves to be accurate enough, the "easiest" path to cross the step seems to be to the left (NE).

Firefox does not display the attached image's link for me. Is the link ok ? Thanks !

Ahh - I think what happened was that he uploaded an image with one post, but didnt put any content in it - and I accidentally deleted that post as it said something along the lines of duplicate or delete or something on it.

T - you might want to re-attach the attachment to another post.

Ok, I simply edited my previous post and included the attachment again.

... and here below is a raw comparision of the official route map and my own version...

Very interesting update! Thanks for noticing it Tesheiner.

The top of the steep step was always very hard to see on the MOC images, nice to have it added. If the bottom of the steep step is where it appears to be then it is much longer, and hence shallower than I thought. We can't be far off being able to see the bottom of the slope meaning it's not much steeper than the the current minimum (17 degrees).

Of course there could still be dangerous outcrops but I would be a lot happier trying to manouver around them on a 20 degree slope than something close to 30.

James,

P.S. Don't be embarrassed, I think your map was the best that could be done with the information we had. I spent ages staring at pans trying to work out where the top of the drop-off was on the MOC images and couldn't come up with anything!

Great new traverse map, with colors and contour lines:

Doug, may/can you make such a cool three-dimensional image of it again?!

Spirit is on the move again, and I have a seat with a view.

I'll switch to the color view (Sol 594-597) when Spirit is more visible in it.

I already tried to do, but I stopped the work when I noticed the very bad agreement in slope between B/W image (with purple level curves) and right portion of colored map. Consider the critical actual rover position, halfway between the two maps!
Maybe Doug will solve the dilemma...

If I had the time, I would, but busy busy busy unfortuantely

[dilo]

OK, I completed the work by making a compromise between the two maps (I suspect that colored one is more recent/accurate, but cannot ignore the surrounding topography!).
Herebelow I report the elevation map (a gif with gray levels stretched in order to cover all elevation range of the map, which is about 80m) and an anglyph on the most interesting side...

Thanks Dilo, the anglyph shows a nice valley-like route down to the basin.
