High on 'West Spur'

A rock outcrop with a view of the surrounding landscape beckons NASA's Mars Exploration Rover Spirit on sol 203 (July 29, 2004) of its journey of exploration on the red planet. This view is a mosaic of images taken by the rover's navigation camera at a position labeled as Site 80, near the top of the "West Spur" portion of the "Columbia Hills." Directly ahead are rock outcrops that scientists will examine for clues that might indicate the presence of water in the past. In the upper right-hand corner is the so-called "sea of basalt," consisting of lava flows that lapped onto the flanks of the hills. The view is toward the south. The field of view is approximately 170 degrees from right to left and is presented in a cylindrical projection with geometrical seam correction.

'Diamond Jenness': After the Grind

This microscopic imager mosaic taken by NASA's Mars Exploration Rover Opportunity shows the rock dubbed "Diamond Jenness." It was taken on sol 177 (July 23, 2004) after the rover first ground into the rock with its rock abrasion tool, or "Rat." The rover later ground into the rock a second time. A sliced spherule, or "blueberry," is visible in the upper left corner of the hole. Opportunity has bored nearly a dozen holes into the inner walls of "Endurance Crater." On sols 177 and 178 (July 23 and July 24, 2004), the rover worked double-duty on Diamond Jenness. Surface debris and the bumpy shape of the rock resulted in a shallow and irregular hole, only about 2 millimeters (0.08 inch) deep. The final depth was not enough to remove all the bumps and leave a neat hole with a smooth floor. This extremely shallow depression was then examined by the rover's alpha particle X-ray spectrometer.

On Sol 178, Opportunity's "robotic rodent" dined on Diamond Jenness once again, grinding almost an additional 5 millimeters (about 0.2 inch). The rover then applied its Mössbauer spectrometer to the deepened hole. This double dose of Diamond Jenness enabled the science team to examine the rock at varying layers. Results from those grindings are currently being analyzed.

The image mosaic is about 6 centimeters (2.4 inches) across.

'Diamond Jenness': Before the Grind

This microscopic imager mosaic of the rock called "Diamond Jenness" was snapped on sol 177 before NASA's Mars Exploration Rover Opportunity ground into the surface with its rock abrasion tool, or "Rat." Opportunity has bored nearly a dozen holes into the inner walls of "Endurance Crater." On sols 177 and 178 (July 23 and July 24, 2004), the rover worked double-duty on Diamond Jenness.

If the rovers continue to operate they may eventually uncover the Kerry/Edwards campaign headquarters.

Engineers believe the problem likely involves the timing of instruction signals reaching the component, called a gate array, within microseconds of each other.

I would hazard a guess that they tried inserting a couple of inverters.

When I read "despite bugs" I thought of those things in Starship Troopers...

Could be, but I doubt they'll ever find Clinton's legacy. ;-)

It's sitting hidden away under a pile of books in a dusty old books section of a book shoppe near Oxford.

Weren't they suppost to konk out months ago?

Despite Bugs, Rovers Still Explore Mars

I thought Bugs got rid of that martian gremlin. What a ignoraminus.

[NormsRevenge]

Yes, the life expectancy for both has been greatly exceeded and they are still moving, so..

[ProudVet77]

American engineering. None better in the world.
Just ask the MSM.

[CurlyBill]

I cannot believe that this photo hasn't generated more discussion.

[1rudeboy]

I read this stuff with mouth agape. Hooray for us!
BTW, "despitebugs" is not the most effective keyword.

[NormsRevenge]

I hear ya.. just imagine the stuff they haven't released. ;-)

[Strategerist]

Every single photo taken has been released.

[Frank_Discussion]

I agree. That bone-like, fossil-like feature in the center is very interesting. I wish the image was in color! Earthly fossils often have a distinctly different color than what they are embedded in. I wonder if this is the case here.

[NormsRevenge]

Thanks. (adjusts my tin foil hat)

ON to Cydonia!!! :-)

[Plexi]

I would hazard a guess that they tried inserting a couple of inverters.

More likely a couple of NO-OPs in the code.

[CurlyBill]

They've already concluded that there was probably water in abundance on Mars...perhaps lakes, streams, maybe even oceans. Water is the main ingredient for life.... to think that this may be a fossil is not a stretch in the least. What I can't understand is why mainstream science won't at least discuss it.

> outlasted the planned length of their primary missions

Made in USA -- I hope.
