Dear List,
 
Another curiosity that I struggled with intellectually while out there on the lakes was this controversy over the find ratio of lunars to martians (It currently stands close to even, I beleive). It's easy for me to holistically contemplate that, all other things being equal, it should be a lot easier for lunar material to get here than mars material; like shooting a shotgun at something 10 feet away vs. 1000 yds away. Mathematicians have calculated that there should be (all other things being equal) a 5:1 ratio of lunars/martians. So what are the factors that cut the odds to 1:1? Some have suggested that some material labeled martian might actually be from here . . . skewing the ratio. I'm not real sure about that since our understanding of isotope ratios is good enough to ID such material for what it is. What do you guys make of it? Is martian material more survivable? Is it really "in range" and not anomalous to begin with?
 
Meteortically yours,
