QUOTE (djellison @ Sep 5 2006, 10:59 AM)  Well - I'll still ask the same question - why do the images look fuzzy because of a 'stretch' process? Doug It is according to Phil's post http://www.unmannedspaceflight.com/index.p...ost&p=66774 The AMIE image is enlarged to match the scale, hence its fuzziness. Rodolfo |

QUOTE (garybeau @ Sep 3 2006, 07:07 PM) True, the actual crater may not be visible, but the ejecta may change the albedo for a much broader area on the order of hundreds of square meters. But even this may not show up with a wide angle view. I look forward to some high res pictures of the area. But there are some slightly visible changes on the ground from the 15secs before and 15secs after the impact images: http://i16.photobucket.com/albums/b14/ustrax3/smart1.jpg -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

I was about to say... How do you know it's changes to the ground and not an ejecta cloud..
Then I thought -hmm - I'll do some image work myself - where's the movie... Then went to find it and found this http://sci.esa.int/science-e/www/object/in...fobjectid=39968 Doug |

is that a simple differencing of the images wrt the pre-impact image? Looks cool though!
edit - here's the animation of it...you can clearly see somthing hitting from above and then making a crash landing like longjumpers do http://www.cfht.hawaii.edu/News/Smart1/#Dust |

I knew I should have done this earlier - not as good as the official one ( but we're not privy to the proper data ) - however something is visible.

Doug and Remcook,
Yes, that's clearly visible on both animations I'm surprised by the behavior of the cloud that seams to go sideway like blown by the wind. Do you feel the same? -------------------- |

I don't see the dust drifting sideways. It looks pretty much ballistic to me. Whether or not the dust was kicked up evenly is another story -- it depends which direction the craft was coming in from. If it was coming from a NNE direction, that's about consistent.

Besides, I have seen a cloud of dust when the Lunar Module takes off from the Moon in a mpeg film. I think you may discover it at http://www.hq.nasa.gov/alsj/a17/a17v_1880127.mpg.
A light color dust around the takeoff site covered the black sky. However, I think that the Moon surface is not so dusty as the ones of Mars and also to some Earth places. I was surprised to see that there is not much dust around the take off in spite of the fact the surface has no cement but on an open surface. Then, I am supposing that the amount of dust of Moon surface must vary according to the some kind of ecological process. The bombardment of meteorites originates the most dust from Moon surface. The rest, no known. For Earth part, the dust is the product from hydro and aeolian force along with the oxidation process caused by the oxigen. But, Moon has no oxygen but it can only be found on silicates that it is very hard to separate from silicate only by after an over than 1,000 -1,500 C. Also, Moon has no aeolian and hydro or any other gas state that might erode the Moon surface to make dust. Where does the Moon dust comes from?  Rodolfo |
