Hort;

April 1; Hmmm!

But did you change the images in any way? Are they real? If so does anyone think that the image might say something about the moisture status of the materials in the "tumbler" over a fairly long time frame?

Winston, no April Fool's joke. I only applied a square root transform to highlight shadow details.

A number of images were taken of the right front wheel yesterday ( sol 2555 ) and today ( sol 2556 ) a verry long drive was done - so it will be interesting to see the changes to the soil and rocks inside the wheel.

I wonder if it is possible to draw any conclusions about the soil by observing how high the soil is sticking on the inside of the wheel...

Could it be they were imaging the JPL inside the wheel?

sol 2363-2556 ( Sep 17, 2010 - Apr 3, 2011 ) L2 comparison of horizon and sky looking towards Endeavour crater:

The summer dust haze is pretty awful.

Only a tau measurment and a navcam "movie frame" image were done today ( sol 2557 ) - so we should see some of the backlogged science images today.

Looks like LA smog where you can barely see the San Gabriel mountains!

The MER team do all the weekend planning on Friday, so there can be only one manual drive in the weekend period. Also, depending on the alignment of the Earth day and Mars day, there are periods when they can drive every day, and times when they can only drive every other day.

sol 2551 ( mar 29, 2011 ) L2L5R2 synthetic false color of the rock "Bagua":

with location and detail links.

Still waiting for the L7 filter - but I thought an early look might interest some rock guys. There are lots of hints of not-hematite "blue" in the rock.

Here is the infrared / visible saturated false color 3D of Bagua.

Sol 2666 L2 4x1 in the next drive direction:


The sol 2556 traverse map indicates the sol 2556 drive was about 133 meters. A drive like this every other day would get Oppy to the rim of Endeavour in less than 100 days!

Today ( sol 2558 ) was another driving day on a 108 degree ( ESE ) heading and if the drive after that is on the same heading and the same distance then Oppy will be on a large patch of bedrock.

There does not seem to be anything ahead apart from outcrops that would warrant a science stop so looks like it's hammer to the floor time.

Been a long drive already! I really hope Oppy makes it.

Today's drive ( sol 2560 ) is underway as I type.

The sol 2560 ( today ) drive site-index changed from B3EP to B3XK for a change of 679 during a 4 1/2 hour drive. My guess is that the drive was about 130 meters - putting Oppy on the edge of the large outcrop just ahead - which puts Oppy about 4 km from Cape York!

At the current pace Oppy could be at the rim of Endeavour in 50 more sols!

Maybe it's time to start an Endeavour rim Arrival date Pool.

I'll go first: May 27, 2011

I think we are actually about 5 km from Cape York. Santa Maria was about 6 km and we will have driven about 1 km from there by the end of the week. We can drive on average about 4 Sols per week, so let's say 1 km every 2 weeks if we really push it. That's 10 weeks of driving time. Let's allow for 5 science/wheel-rest/diagnostic stops, each taking a week. That makes 15 weeks in all, which takes us to July 23. I don't think we will really be able to maintain that pace, so I'm going to guess August 20 for my pool entry.

Re: Reply 29, that shot of the tracks, what is making those regular off track tracks as it were. Are the wheels twisting off at and angle every meter and then back on track again. Why?

Kevin, if you follow the link to the Flickr image you will find a comment explaining the track pattern. I encourage all readers to follow the Flickr link for more information.

For example, if you follow the link to the pan in this reply you will find a link to a pancam panorama in the next drive direction and a link to a change to the sundial stain.

Barsoomer - oops. when I moved the position of the rover on the detailed map to the larger map I misplaced the location by a km or so and didn't do any cross checking. Your estimate of the arrival time is more realistic.

Thanks Hort didn't scroll down, will do in future, good catch. This manouvering will slow things a bit so I shall go for circa Sept 10th.

Today's drive ( sol 2561 ) advanced the drive index from XK to 8Z for a difference of 321 during a 1 1/3 hour drive - for a guestimated drive distance of 60 meters.

Hort's reply 26.........that rock deserves discussion. Besides being unique compared to the zillions images of layered rock with berries, the image is in my opinion one of Hort's greater works.

Agree John, technically it's perfect aligned and shows the really "what this is". Thank you Horton for your good work and efforts here.

John, Mizar; agreed!
