Now that we know where we are going, I thought we could use a topic about our future route. I hope that a few images will get the rover rolling - downhill.

READY START

BACKGROUND
------
From Steve Squyres Misson Update
Octoberber 4, 2005

Extending eastward from the summit of Husband Hill is a broad ridge that we've named Haskin Ridge. It trends ENE from the summit, does a little dog-leg to the right, and then trends ESE for a bit. Right at the dog-leg there's a pretty steep step, which we're not certain we can get down. So we're going to descend the upper portion of the ridge, right to where the step is, and assess the situation. If we can see a safe route, then we'll continue down onto the lower portion of Haskin Ridge.

My Image of Haskin Ridge
I tried to get the best image of Haskin ridge that was available, and this is a crop from a true color TIFF summit panorama, located on the the Cornell Pancam web site. I converted the tif file to a gif file to save some download time.

PS If you can't see the "steep step" that Squyres mentions - try this orbital image. I believe that the "steep step" is the dark shadow cutting across the ridge that is located directly under the word CRATER. I think that it is also visible in the true color pancam image, but it is less obvious.

... we could easily come across long outcrops running along the side of the hill which could be very tricky obstacle ...

True, true... as you say, we just have to go along for the ride and see...

The immediate question we face (the 'steep step') won't be the only one coming up in this descent - from what I can see there's going to be several dicey points on the way to Home Plate. With a little luck, we can hopefully avoid the need to reverse our path! Wouldn't that be the pits!

Have a great one...

No better than the navcams really but attached is a screen grab of the Sol 637 drive direction Pancam thumbnails at Pancam data tracking.



Would make a nice pan of where we're headed if the full versions would turn up

A Sol 638 version is also down but thumbnails are not showing up yet.

James - Addict, hoping I won't have to keep reloading Exploratorium every five mins for much longer.

And with that - it's back!

I don't know If you'll be able to see this better in stereo images (I don't have glasses) but using the parallax calculator It appears that there are no features between 30 and 80 meters in the dead ahead direction.

i.e in this image,




Terrain below the added line is closer than 30m above, further than 80m! 50 steep, unknown meters.

Wait a minute, James!
Did you get those pictures directly from the pancam tracking web? How?

Edit: Sometime ago I was playing with that "display_jpeg" button on the webpage with no results. Any trick?

Right. But if you have a look to the pancam picture left of the one you mentioned (2P183010735EFFAH00P2388L7M1, see below) there IS a path i.e. continuity which avoids the step.



In two days (drives) Spirit may reach that point.

After a few meters driving down Husband Hill, a new panoramic view of Haskin Ridge.

Trying to find the right way down the step.

Nice pano Jvandriel!
Let me use it to extend on my last comment, if you don't mind.

That's the pancam panorama taken after sol 638 drive. The step can be seen on the three rightmost frames, while the path I painted before can be seen a bit to the left of the center.

[jvandriel]

Tesheiner,

I think you are right. The only place where Spirit can cross that step is where you

painted the route and a little bit more to the right.
