Many high value specimens are sold in extremely small part slices, particularly lunar and Martian meteorites. A sub-gram fragment of a shergottite from the planet Mars may look uncomfortably similar to a blob of cement, so it is critical to know that you are purchasing from a reputable ...
2) Lunar meteorite. Lunar meteorite sold for $500-$1000 per gram. If you had bought several kilos of lunar back then, you would be losing your shirt now. Lunar now retails in the neighborhood of $100 per gram, sometimes lower, and a lot lower at wholesale. I know guys sitting on ...
The threshold collisional specific energy, Q* D, for these NWA 869 targets is 1795J/kg, more than twice the literature value for non-porous terrestrial basalt, but significantly lower than the 2380J/kg value we measured previously for highly-porous terrestrial pumice. Volatile-rich matrix was ...
I estimate that for a short-period instrument, with a noise spectral density of 108ms2Hz1/2 in the 1–16Hz frequency band, approximately 0.1–30 regional impacts per year should be detectable with a nominal value of 1–3 impacts per year. Therefore, small regional impacts are likely to ...
I estimate that for a short-period instrument, with a noise spectral density of 10−8 ms−2 Hz−1/2 in the 1–16 Hz frequency band, approximately 0.1–30 regional impacts per year should be detectable with a nominal value of 1–3 impacts per year. Therefore, small regional impacts...
Xu Weibiao, a meteorite expert from the Purple Mountain Observatory in Nanjing, says meteorites can sell for even more than that – above $10,000 per gram. "The rareness of the meteorite decides its market value," Xu says. "Except those people who really know meteorite and its importance,...
