We have determined the abundances of ^16^ O, ^17^ O, and ^18^ O in 31 lunar samples from Apollo missions 11, 12, 15, 16, and 17 using a high-precision laser fluorination technique. All oxygen isotope compositions plot within ยฑ0.016 per mil (2 standard deviations) on a single mass-dependent fractiona
