Reading Ray Villard's article "Did NASA fake the Moon landing?" in the
July "Astronomy" I was interested to read that although the experiments
were turned off in the 1970s for budgetary reasons (I understand they
were also simply not returning useful data), the transmitters are still
working and still being used. That's very impressive for 1960s
technology, given how hostile the environment is there.

But I think there's a horrible mistake or typo.
"Ancient anthracites, lava basalts, and breccias".
Unless anthracite means something other than coal?
