    It is generally believed that the lunar surface consists primarily of silicates, and that these may exhibit significant adhesion under the ultra-high vacuum conditions present. This paper presents results to date on a study of the possible adhesional behavior of lunar silicates. To place reasonable bounds on the range of lunar adhesional phenomena, and on the degree to which these phenomena can affect lunar missions, two types of silicate surface have been considered. The first is a surface which is contaminated to the degree that the charge and coordination demands are satisfied. The second is the ultra-clean surface.
