2 items: 1) I ran across another link related to lunar timing. Last year Carroll Alley died (89). To me he's famous for his cesium and H-maser relativity experimence in the 1970's. But he was also the PI for the Apollo Lunar Laser Ranging Retroreflector experiments. More info here:

Anyone recognize more gear? /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
