If it is any conciliation NASA is just as bad. Enjoy your artwork.

This is what I don't get about the 'fringe'.  Back when MER landed, I started from scratch to build a pipeline to make color from calibrated images.  Guess what...they came out looking like the official releases.  Wouldn't that stand as some degree of confirmation that they had it right?  I guess there's just no  way to convince people if they're not willing to give up their preconceived notions of what it "should" look like.

Well I guess its all down hill from here. Give us that Crotty haze.

Don't shoot the messenger.  I'm not doing any hand-editting, just showing what the pictures tell us.

Crotty seems to be getting a little better. Still a little too red. You can make out a little detail. Looks like he is not trying to stuff 20 lbs of data in a 10 lb bag anymore.

It's the same algorithm I use for the raw images from MER (the calibrated galleries are a different story).  Since I'm not using any calibration yet, the output color is entirely dependent on how far the raw images have been stretched when they are packaged up for the web.

Would 18% be enough to make ISRU worthwile taking this approach

Why not?  It wouldn't take much of a temperature increase to begin dehydration, as low as 50 C for some of the ferric sulfates, and no higher than 300 C for some of the other sulfates found in the same hills.  Spirit has seen sulfates in many different positions around the Columbia Hills, so probably safe to assume these deposits are plentiful.  This stuff would be an easy and readily accessible resource, although it may be location specific.

To me, it look like the object moved, telling me it could be one of Mars' moons.

The left and right frame should have been taken at the exact same moment as they do have the same timestamp.  It doesn't show up in other left navcam shots, so its not a consistantly bad pixel, though it might have been other mechanical problems (cosmic ray hit) causing one really bright pixel, which after compression spreads out into the fan pattern you can see zooming into it.

Does anyone else have a bit of news I may have somehow managed to overlook?  Of course I'll continue scouring resources myself, like usual.  smile

They do seem to be slowing down with the updates, both the video Flight director reports and written accounts of the rovers.  But, they are still having press conferences on a fairly regular basis, but they've moved off video / NASATV and on to tele-conferences.  There are audio streams of the most recent pair are available on the JPL website ( http://www.jpl.nasa.gov/multimedia/]htt … ultimedia/ ) from November 11th and October 8th.

Opportunity spotting something near the sun...

looks like about the same size as Deimos, from the deimos transit Opportunity viewed on sol 39 :

The RAT tool must return some sort of data on how hard it had to grind to get through the surface.

There are a couple pieces of data that the RAT returns that will be included in the PDS release of data.  From http://pds-geosciences.wustl.edu/missio … ve.pdf]Mer PDS Archive Docs:
Rock Abrasion Tool Experiment Data Records: time-ordered actuator current measurements, temperatures, and encoder values

They don't list any derived data products there, only the 'raw' data, but with proper calibration... (from "The Rock Abrasion Tool, Mars Exploration Rover Mission" Gorevan et al, 2003)

"From the motor currents, torque can be directly calculated and torque can be empirically correlated to the density and hardness of the rock. Combining these parameters, along with a close-up view from the Microscopic Imager (MI) of the fresh surface, one should be able to properly assess the compositional and the depositional histories of the rock."
