Endeavour Crater, And again shall we conquer the Remoteness Options

[marswiggle]

Using Google Earth (Mars), I was able to pinpoint the lowest and highest points of Endeavour pretty easily. Remarkably, the lowest point (-2006 m) seems to be located just at the base of the eastern wall, 3.65 km due west of its highest point (-1309 m). So the east wall is quite dramatic, and actually about as high as Victoria Crater would be if tossed onto its side, its minor axis pointing up. (If you can imagine that.)

Coordinates:
lowest point - 2˚22'22" S, 5˚04'53" W
highest point - 2˚22'23" S, 5˚01'10" W

So, the difference between the lowest point and the Cook Peak is about 700 m. And how many degrees has wall's inclination ?

Plugging numbers for side c and side b into this online trig calculator, I get an average slope of 11 degrees.

That's not too bad. Certainly hike-able without too many problems. And certainly, Opportunity has had to deal with worse slopes at Endurance and Victoria, right?

[Station]

11 deg only ? At first look the slope seems to be much more dramatic, at least on those 3-d generated pictures.... Well, now I can see those simulated 3-d pictures don't match reality..
You r right volcanopele, in such case Opportunity should have no problems to "climb" there. In Endurance crater there our brave rover had to deal with worse case.

11 deg only ?

Looking at the 3d image, the slope seems flatter near the bottom of the crater and steeper near the rim. The 11 degrees is an overall average. Maybe separate calculations could be done for the lower and upper parts.

Is that slope anywhere near where Oppy might arrive? - And how is the drive down from a sun angle perspective?

700 meters: that is one heck of a stratigraphic cut...

You can generate elevation and slope 3D maps with HRSC View.

And we ought to hang our heads in shame that we no longer accept the challenge to do this kind of thing on paper, with a quick glance at the trig chart pinned above our desks.

Does anyone still have their CRC log table books?

[PDP8E]

I still have my Chemical Rubber Company (CRC) book of logs around.....

[Floyd]

Yes I still have it. Didn't even toss it out when I got my handy HP35 calculator for $360 (ordered it before it was actually released).

[Greg Hullender]

Ah, but is your trig table old enough to have versines and haversinies too?

--Greg :-)

[Floyd]

Am I correct in that haversines were used extensively in setting up the curves in railroad tracks? I'm old, but wasn't around in the 1850s.

[Guest_Enceladus75_*]

I'm just wondering that as Oppy gradually approaches Endeavour, and since it was able to glimpse tiny parts of that crater's rim from Victoria, then surely some more of Endeavour's rim peaks must be coming into view now?

I'm a sucker for distant views on Mars of mountains and hills. So does anyone know of any images taken by Oppy in the past few days showing parts of Endeavour?
