Interaction of gases with lunar materials - Revised results for Apollo 11The surface properties of an Apollo 11 soil sample have been reinvestigated. The present study shows that the preliminary results for this sample (Fuller et al., 1971) are in error, principally because of incorrectly applied instrumental background effects. The surface properties of these Apollo 11 fines are very similar to those of fines from the other Apollo landing sites that we have examined. On the basis of results reported to date, the surface properties (specific surface area, porosity, and reactivity with water) of lunar soil samples are, to a first approximation, independent of bulk chemical composition and location on the lunar surface. Drastic alteration of the surface characteristics of lunar fines by adsorbed water continues to be the distinguishing feature of their surface chemistry.
