It is time for a new thread now Spirit is on it's way to McCool Hill to survive the Marsian winter.

Here is a panorama from McCool Hill taken on Sol 777 with the R2 pancam.

Almost from the same place as the panorama taken on Sol 776.

Anyone want to hazard a guess as to her path up McCool Hill?

The route is under discussion at :

I think the boundary of the lighter colored deposits on the hill will feature prominently in the path chosen

If you're talking about the broad swath on the upper right hillside, I doubt we can go there till spring. It faces more west than north. I don't expect we will continue moving toward Oberth for the same reason. Once we cross the valley, we need to head toward Korolev. Actually, I think we need to approach Korolev on the flat, and only start to ascend when we get close. Tilting the solar panels westward will not help us.

This hill is higher than Husband Hill, who is at 90~100 m. So, this hill may be 120 - 130 m high, I think...

JPL article about McCool being taller. Li's team estimates McCool Hill to be 436 feet, 133 m above Spirit's landing site (compared with Husband Hill's 351 feet, 107 m elevation above the landing site). That is to say that McCool is 85 feet or 26 m higer than Husband Hill.

Note the above values are elevation above the landing site, not the elevation of the hills from their base on the plains.

Green slope good, red slope bad - very rough and ready, but it gives some sort of idea smile.gif

Do you have that DEM?

Amazing. How was this produced? But it makes it look like we should be running southeast from HP, not northeast. Why am I confused? blink.gif Is the dark green to the SE way up near the summit?

We are going SE generally. Any one day's drive may not be in the exact direction of the over all goal - but it may be the best route that offers progress in the route required.

That was made using an elevation map derived from a DEM (which Helvick should have shortly ) and then in a 3D animation package - I simply put a green light source to the north, and a red one to the south - so the related slopes were illuminated appropriately.

Thanks for a wonderfully helpful quick and dirty solution smile.gif

My only concern is that it might miss some of the forenoon and afternoon illumination. Could you consider another try adding other greenish lights at northeast and southeast; perhaps blue-green at one corner and yellowish green at the other.
If you need precision, and your spherical astronomy is fresher than mine rolleyes.gif , you could compute the illuminaton angles for winter solstice around 0900 and 1500 Local Apparent Time.

OOPS -- I meant northeast and northwest

I intend to do something like that but it's going to be later in the weekend - real life work has cought up with me big time and I have some deadlines to meet.
My plan is to integrate the daily insolation in hourly slices. The current model that I have takes about 100 seconds to do a full martian year on a Sol by sol basis _for_ a single position using a 20 minute time slice so I should be able to generate a 1024x1024 grid in about 30 minutes for a single sol. I think. I can cache a bunch of intermediate calculations for this though so I might be able to get an order of magnitude maybe even 2 of a speed boost once I look at it properly.

A panoramic view on Sol 781.
