Vehicle on moon may sink into fluffy stuff

From the issue of March 23, 1963

The surface of the moon may be covered with deep layers of fluffy material into which landing vehicles could sink out of sight…. Research so far has shown that loose particles hit by meteoroids settle down into the moon’s rock or mineral surface. This surface becomes exposed to radiation and breaks down into fine particles of dust. The dust coagulates into larger and larger clumps…. Observed characteristics of a cement powder have been found to match the reflection characteristics of the lunar surface. The conclusion is that the surface of the moon is likely to be composed of cement powder that has a cobweb-like structure.
