Ya, I just noticed they recently said the Meridiani dunes are not being deposited but uncovered by erosion. Even though I barely remember which side of a dune is the lee side, it was obvious almost a year ago this was the case. I mean when you see the cross stratification of ...all...of the Meridiani dunes what other conclusion is there? When you see this, the only explanation is the sand dunes were buried and later exposed by dunes forming from an entirely different direction. I would think this means the wind dunes were covered by a shallow sea and covered by a new sea floor. Then later modified by wind again. Alternating periods of dry and wet. http://marsrovers.jpl.nasa.gov/galle...P2407R2M1.HTML Cross stratification in dunes http://www.windows.ucar.edu/tour/lin...sed_dunes.html http://3dparks.wr.usgs.gov/zion/html/3d154.html But the horizontal racing stripes on ...all.. the slip faces at Meridiani is a good mystery. I can only guess the stratified dunes were soaked when part of the sea floor. http://marsrovers.jpl.nasa.gov/galle...P2434R2M1.HTML Maybe the stripes formed like this? http://www.nps.gov/yell/slidefile/th...ages/05337.jpg Nasa keeps saying the rocks are billions of years old at Meridiani, fine. But that implies it's been geologic time since water was there. I don't think so. To guage how long ago water might have bubbled up from below, look at the distinctive and delicate erosion pattern shown in the ....shadows.... cast by these two pics. Certainly not geological time scales, but maybe as ice ages wax and wane. Or less. Yellowstone mudpot http://www.nps.gov/yell/slidefile/th...ts/midwaylower... Endurance mudpot http://qt.exploratorium.edu/mars/opp...4-07-16/1P1431...

Here's another view : http://www.flickr.com/photo_zoom.gne...2295085&size=o Since it hasn't eroded away, one can presume, actually one can easily see, that the ejecta splat fragments are harder and from a deeper layer of crust. It was a spectacular opportunity to take a closer look at some fresh material from a much deeper statigraphy and they breezed right by, not even an acknowledgment from the science team. That's just nasty. We are talking butt ****ing dumb geologists here. They don't give a **** about this mission anymore, they just want panorama's for the dumb****s. That easily has to be the clincher that science management on this mission has been grossly (terribly) mismanaged from the very start. Ya, I just noticed they recently said the Meridiani dunes are not being deposited but uncovered by erosion. Actually, they appear to be forming in place, sculpted by the wind as the regolith outgasses and decomposes on the spot, in situ. Let's see what happens at Victoria, it should be quite the show. And that's all it will be, a show. They given up on the science. http://cosmic.lifeform.org |

...Rover Only a Half Mile from Lake Victoria!!!
I personally want to see the lower reaches of Hellas Basin
It is very deep and I have not as yet been able to determine the atmospheric conditions there - temp, pressure, water vapor etc. IMHO Hellas is THE primo site for human exploitation. But thats just a bald assed opinion, not based on facts, cos I can't get the facts... It is so deep it could act as an atmosphere trap.... |

...Rover Only a Half Mile from Lake Victoria!!!
Next to the spheres, Victoria should easily be the highlight of the rover missions. Download the large image of Victoria Lake (not crater) at the very bottom of this page. The first thing I wish to see up close is the 'dark streak' flowing from the rim wall at the very bottom of the picture. The result of recent water flow perhaps??? http://marsrovers.nasa.gov/gallery/p...20060505a.html And what is causing the unual erosion of the rim of Victoria? And why are the dunes on the floor off-center at both Endurance and Victoria? Could this pic explain both questions? http://www.picturesofplaces.com/pict...n-spring/large And just in case anyone has forgotten about those spheres.... Paleoenvironmental Interpretation of the Dakota Sandstone as a Mars Analog, focusing on Concretions http://chapters.marssociety.org/cana...ssaBattler.pdf Concretions Concretions usually form during the early stages of diagenesis under the influence of bacteria, soon after deposition of sediments, and at shallow burial depths (Irwin and Curtis, 1977); (Mozley and Burns, 1992), ...Concretions commonly form around a nucleus composed of a dead organism, and grow due to bacterial decay of organic matter (Fairbridge and Bourgeois, 1978). The current understanding (based on isotopic data) is that many concretions form biogenically, as exemplified in papers by Coniglio and Cameron (1990), Mozley and Burns (1993), Klein et al. (1999), and Coniglio et al. (2000). If the acidic lake or a hot spring environments indicated by jarosite existed at one time, they could have supported life. The discovery of bromine is significant because it indicates that a large body of water existed on the surface of Mars for a long time, and thus surface temperatures were once warmer than they are today, possibly enabling life to flourish (Britt, 2004b). The discovery of concretions on Mars is profound because many concretions on Earth form biogenically. Thus the Martian concretions might be a strong indication of the past existence of life on another planet. Mars Analog Conclusions Given recent discoveries on Mars, the Dakota Sandstone has turned out to be a better analog for Mars than anyone could have predicted. The Dakota Sandstone provides many pieces of evidence for past water and life. The concretions, in particular, strongly indicate past microbial activity. The Mars Exploration Rovers found additional clues that indicate past water on the surface of Mars. The mineral jarosite - a hydrated iron sulfate which forms through the interaction of iron, sulfur and water - was discovered, indicating the past presence of water, possibly in the form of an acidic lake or a hot springs environment (Malik, 2004).
