I have 999 (really!) line items of samples from the 6 Apollo and 3 Russian Luna landing sites from NASA. I can think of only 1 or 2 other researchers who might have more. The total mass is 320.064 g (0.08% of the collection). That's an average of 0.32 g/sample. But, even that number is misleading. The mass distribution looks like this. http://meteorites.wustl.edu/Korotev_NASA_Apollo_&_Luna_samples.jpg Only 49 of the samples exceed 1 gram is mass. All of the samples >3 g are not "rocks" but regolith (alias soil or dust) samples. The smallest samples are all thin sections. My point is that every article about this issue shows a photo of a big rock, and NASA just doesn't issue big rocks to us researchers. As someone else mentioned, I suspect the actual mass of missing material is not large. Randy Korotev Received on Mon 12 Dec 2011 03:13:42 PM PST |
