Weird stuff on Mars !!!

It isn't their business to provide public annotation for every image they collect. This is a scientific expedition, with a fairly short window of data collection. The investigators are under no obligation to provide any short-term information at all. They've done a good job of providing press releases highlighting key events and finds, and provided a great courtesy in releasing so many raw images. By virtue of its public funding all of the raw data will be available in short order, and the specifications of all the instruments are already available. Lighten up. _________________________________________________ You are way over the fence on this one. You should lighten up. It is standard geological fare to provide actual measurement scale in any photo of a geologic feature. The least they could do is tell us what the millimeter dimentions of the feature s are. They did say once that the Opportunity outcrop features were measured at 4 inches high. |

The images we are discussing here are in the raw images section. It is perfectly acceptable for them to provide no annotation at all beyond the basics that can be extracted from the file name. These aren't press release images, which do have more information supplied (and I certainly agree it would be customary and appropriate to give some information on scale in a press release image). Raw images are supplied so that individuals interested in pursuing their own investigations have data to work with. Anybody competent enough to do something useful with these data should also be competent enough to look up the technical specifications of the instruments used to collect it. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

"jerry warner" wrote looks like micro volcanic or heat deposited glass beads of some kind. note the sharp fracturing & pitting on several which is characteristic of such materials found in nature, but Im liklely wrong. Check out this colorized shot, where the spheres appear bluish, which is handy for spotting them. Note that they are embedded in the outcrop rock, so they are evidently weathering from that source. http://www.copperas.com/astro/spheres.jpg The rock they are coming out of looks very weak (like ash?). Be a lot cooler if it is sedimentary rock though. Joe |

If you think THAT'S weird, try driving down Harry Hines in Dallas some time.

release image). Raw images are supplied so that individuals interested in pursuing their own investigations have data to work with. Anybody competent enough to do something useful with these data should also be competent enough to look up the technical specifications of the instruments used to collect it. _________________________________________________ When you say that the FOV of the image is 31 x 31 mm I take that as meaning at the plane of the CCD image much like a SLR 35mm image. So what if my pictures are 5 x 8? I still cannot make any inference about the size of ojects in the picture. So, what does it matter if the FOV is 31mm x 31mm? This is 2 dimensions not 3 and perspective is at play. I really think you don't know what you are talking about. If you did you would just tell me what the size of those beads are based on your "technical specifications". |

You are either really thick headed *and* self righteous or you are just another troll. My bet is on the latter. Shawn Grant as a girl.
