You could measure it yourself with Google Earth and ET's maps.

True! Or go to post 5 on page 1 of this very thread for a map with a 1 km grid, very easy to measure from.

Give a man a fish and he'll put it in the freezer whereupon his wife will throw it out sometime next spring. But teach a man to fish and he'll always be wanting to borrow your boat. Mind your own business though, and such people will leave you alone.

They found a pool of water under a bedrock there and found Flipper swimming around

From Wikipedia:

QUOTE

Pond Inlet (Inuktitut: Mittimatalik, in English the place where Mitima is buried) is a small, predominantly Inuit community in the Qikiqtaaluk Region of Nunavut, Canada and is located at the top of Baffin Island. As of the 2006 census the population was 1,315, an increase of 7.8% from the 2001 census[3] making it the largest of the four hamlets above the 72nd parallel. Pond Inlet was named in 1818 by explorer John Ross for John Pond, an English astronomer.

The naming theme remains consistent! (Polar explorers)

Deimos

Jul 26 2010, 02:43 AM

Going back a couple days ... I mentioned thinking the dust devil may be a gust. I don't think so any more, as a result of an accidental 4:1 reduction in the horizontal dimension of the image. Maybe y'all saw this clearly already, but this is what did it for me. The request for movie/watch activity is in.

It looks like the distance was only around 30 m, based on the images. Perhaps this first trial was meant to be a short drive?

jamescanvin

Jul 26 2010, 08:10 AM

Yeah, if I'm reading the tracking data right, about 20m blind then 10m reverse-auto. I can only imagine that it was an intentionally short first test. They probably wanted a good view of the terrain they were going to test the technique on, rather than doing it on entirely unknown ground (as envisaged eventually) on the first try.

Jul 27 2010, 07:30 PM

The MER rovers can be driven forwards or backwards; I've been wondering whether they can be driven sideways. That is, can all six wheels be turned left by, say, 10 degrees, and the rover driven in a straight line at an angle of 10 degrees to its head/tail orientation? This is mainly idle curiosity, but it was stimulated by the news about the new backwards auto-navigation technique that involves rotating the rover to get an unobstructed backward view.

The center wheel on each side can only steer in one direction, so I don't think it can do it unless the four corner wheels drag them along.

Jul 27 2010, 07:56 PM

I have seen some prototype rovers at the JPL robotics lab that can do what you're describing (which is usually referred to as "crab-walking"). I have a photo of one called Pluto doing that in this old blog entry.

My version of Sol 2311 drive direction

charborob

Jul 28 2010, 03:54 PM

In the latest batch of images on Exploratorium, I find series of images pointed in the same direction spaced about 30 seconds apart. Looking for DDs?

fredk

Jul 28 2010, 05:34 PM

Do you mean the L6 pancam series? Those are super-resolution sequences, much like the previous ones. Normally they use a series of navcams to search for DDs because of the wider field of view. But I'm sure they'd be thrilled if a DD made an appearance in the L6's...

Deimos

Jul 28 2010, 05:40 PM

Sounds like L6 the superres, in which I saw no DDs. Tosol has some navcam DD frames, but most of them are lower priority (as usual).

Stu

Is there a super-res sequence planned of the area in which Cape York is going to appear? I'd have thought you guys would be keen to bag it

Phil Stooke

Jul 28 2010, 06:45 PM

Maybe when it actually becomes visible?

As far as I can tell, the direction to York should be in one of the new super-res views. It should appear in the left part of this frame:
http://qt.exploratorium.edu/mars/opportuni...6M1.JPG?sol2298
It's conceivable that the official super-res will show a tiny bit of York just peeking above the horizon.

I've took the frames that are constituting actually a super-res pan to produce it. The colors are from the same sol.

This was processed with Keiths Image Stacker (align & stacking + Laplacian pyramid sharpen), Gimp (GREYstoration -denoise-, colors), Hugin (pano).

The result is this following image :

If your referring to the mark on the near horizon (as opposed to that distant crater beyond Endeavour) then my guess (without doing any complex analysis) is a particularly large ripple I can see in the maps in that direction about 700m away.

I don't see any sign of Cape York, although much of it would (I think) be off the edge of Ant's image.
