Another Strange object in MER photo
This image is from Spirit :: Panoramic Camera :: Sol 014:
http://marsrovers.jpl.nasa.gov/galle...9P2543R5M1.JPG The lowermost object to the left appears to have a rectangular 'opening' in the face. Similar images are in rows 4-6 he http://marsrovers.jpl.nasa.gov/galle...irit_p014.html Would appreciate anyone's thoughts regarding an explanation. Thanks in advance for any responses. Doug |

Doug i dont see anything weird there. sorry. now, i *do* see a definite hominid skull in the Viking 2 Lander picture. check out APOD's August 22nd picture, Utopia on Mars. if you download the huge jpg at http://antwrp.gsfc.nasa.gov/apod/ima...e_vik2_big.jpg you should get a 1692x1521 pixel picture. making the upper left corner (0,0), put your cursor at x=849 across, y=510 down. enlarge. lower jawbone missing. facing slightly to the left of us. looks like a bullet hole above the left eye socket. right socket hidden in shadow. cant be jimmy hoffa, though, because, according to my size estimate, this skull is about the size of australopithecus or a home sapiens child, at best. - nate |

Nate,
One reply I received offered that the rectangular indication was a shadow - however the sun is shining from the back side of this 'rock' - and so would not be able to cast a shadow on the unlit side. What raises my curiosity are the very straight sides and almost perfectly square corners. Regarding the object you mentioned - at what clock position is the object from the left end of the canister that is in the lower right hand portion of the screen?

I agree it's not a shadow. However, rocks are known for their mottled colorations. This rock only needed to form adjacent to some darker material. Depending on the contrast settings of the camera, it would easily come out looking black What raises my curiosity are the very straight sides and almost perfectly square corners. Perfectly square is an exaggeration. It's a rough polygon. You'll find much more regular-shaped stones at the "Giant's Causeway" in Ireland. In fact, in the rubble around the base of the causeway, you'll find much more regular rocks than the one in that picture. http://www.angelfire.com/wi/shamrock...ages/giant.jpg Also, did my last reply to this thread ever show up? Either Google's not displaying my posts or a lot of them are not getting through moderation. Mike Miller, MatE |

Mike,
Thank you for the reply and comments. I very much wish I could view the image at higher magnification without loss of resolution - or that the MER would acquire a closer image. In looking at the image again - I agree that the black rectangular area is not a perfect a perfect square - although it closely approximates one. Although I am not even an amateur rock guy, perhaps just more than casually curious - that such an indication on a fracture surface is most interesting - how can this occur naturally? Also, the demarcation between the face adjacent areas of gray and black appears rather sharp - not blended. A better resolution image at closer range would remove any doubt about what is being observed. The following is the first post to this thread from you - at least that I have seen. Not sure why other posts would have been blocked - I appreciate your thoughtful response and look forward to your additional comments. Best, Doug |

It might be interesting, but it's very common. Rocks are often very mixed, heterogenous materials. They have all sorts of growths, inclusions, etc. in their mixes. Three possible explanations: 1) The rock formed with an inclusion of some other material, like a nugget of basalt trapped in sedimentary or volcanic rock. 2) The black area is the result of chemical processes in the rock, some segregation or post-formation reactions (like the way a geode forms: crystals growing in rock). 3) The rock formed adjacent to another layer of different rock (like sedimentary rock growing on granite) and the rock fractured off along that flat surface. It mostly, but not entirely, separated from the other rock. A little smear (the black patch) remained on the rock. Mike Miller, Materials Engineer |
