Mars Rover Finds Unusual Rocks at 'Home Plate'

An anonymous reader writes "After several months of driving nearly a kilometer, the Mars Rover Spirit has reached the semicircular plateau dubbed 'Home Plate' in Gusev Crater and has unearthed a puzzle. Spirit first got a good view of Home Plate in late August from 'Husband Hill'. The layered appearance is unlike anything yet seen by the rovers."

Outrage and disgust swept through the community today as the Council of Elders confirmed the rumours that one of the mechanized invaders from the sinister blue planet third from our star has defiled one of our holiest landmarks.

Recently declassified vision-waves from the elite team of warriors dispatched to track the invader's progress clearly shows the horrible automaton stretching out its spindly claw towards the Tracks Of The Founder, a most sacred site for G'loshnaks and Z'treems alike.

K'Breel, Speaker for the Council, stressed yet again that there was no cause for alarm:

"I assure you, this assault upon our holy sites will not go unpunished. For descrecrating the most holy Tracks Of The Founder, a site that no one is even permitted to look upon, the disgusting inhabitants of the Evil Blue Planet have forefited any possibility of mercy. The brave warriors who reported this outrage are even now ritualistically puncturing their gelsacs for inadvertently gazing upon the holy site, and their ichor will not spill in vain!"

When asked if citizens who viewed the sacrilige via the declassified vision-wave would also be required to satisfy the honor of the Founder by ritualistic gelsac puncture, K'breel replied,

"No, the Council of Elders has decreed that a light scourging will suffice. If you have witnessed this horrible act via the declassified vision-wave, please report to your nearest purification center immediately.

At home plate...

Next up, the rover will extend its probe into home plate. If rebuffed at third base, the rover will revert back to trying to get under home plate's sweater.

has unearthed a puzzle

That's unmarsed a puzzle. Typical terran bias.

Looks like sedimentary rock to me.

ObsessiveMathsFreak has it right. That is fossilized sedimentary rock. You can find it all over places like China where several feathered dinosaurs were found recently directly linking dinos with birds.

Anyway, if there is at all a chance of proving that Mars might have once harbored life THIS IS THE PLACE to look. Because its within sedimentary rock that you find the greatest proliferation of fossils. Any self-respecting paleo-geek can tell you that.

I disagree. While the rocks do have the appearance of a striated laminate, there are enough layer thickness inconsistences visible over very short distances that this may not be the case. You can get similar visible features from magma and volcanic flows. Also, some very serious uplift and tilting has occurred (the layers are visible along a horizontal surface) At this point, it's difficult to even pinpoint it down to which of the three major rock types it is (igneous, sedimentary, and metamorphic) without chemical and microscopic analysis. You certainly can't tell from a series of black and white pictures. Which is exactly why there's debate about this among even the experts.

In all fairness

If you read Squyres' book, he knew that 90 days was totally doable, but wasn't sure about much longer. The original plan was for 30 days, but he figured they couldn't get any science at all in that short a time and they needed funding for at least 90. Dust buildup on the solar panels was going to cripple the rovers quickly since they couldn't figure out a good way to clean the panels.

They never expected the Martians to clean the panels off periodically. (Dust devils, actually) Check out some of the recent photos- the panels are amazingly clean, far better than they ever hoped. Even so, the rovers aren't in good shape- Spirit has no teeth left on the RAT and has several steering motors with issues, Opportunity has major problems with it's robotic arm and how the mini-TES is still working without nighttime heat is unknown.
