We might be in a period when, for the couple of hundred years since meteorites started to be recognized for what they are, no lunars arrived where humans were in a position to witness their arrival.

You did a good job of thrashing my response without giving an answere to the original question. Why are there no lunar witnessed falls? DR kortev did say there are twice as many Martian impacts,which to me is a lot or many more. Another person questioned if they would have enough velocity to be seen which is a verry good point because some would reach terminal velocity much sooner than an object from mars or the astroid belt. The amount of time recovered lunars take to reach earth has been said to be the same as mars meteorites. I am beginning to believe it may be a matter of recognition. A lunar would reach terminal velocity 20 or more miles up and fall without making a sound. And if it did make a sound the person finding it would do everyones "is it a meteorite" test. Brown or green crust? Doesnt stick to a magnet.vesicles on the crust. Must not be a meteorite. And what size does it take to launch a rock from the moon?small would do it. > Cheers Steve > > > > > ______________________________________________ > Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html > Meteorite-list mailing list > Meteorite-list at meteoritecentral.com > http://six.pairlist.net/mailman/listinfo/meteorite-list Received on Wed 08 Sep 2010 12:21:51 PM PDT |
