I don't remember much about the landing of the first astronauts on the moon
and I don't want to add to the confusion, but I happen to have a pretty
complete inventory of National Geographics in my room. I hauled out the
1964 March issue, just out of curiosity.
In this issue there is an article "How we plan to put a man on the moon."
On page 382 it states that
"Perhaps the greatest hazards will be found on the moon itself. For
example, we know little about the composition of the lunar surface. Some
authorities believe it may be covered by a dust layer from four inches to
three feet in depth. Others think the dust in some areas may be far deeper,
enough to engulf any spaceship. A third group holds to the theory that
porous rock covers much of the surface."
"Obviously, we cannot risk landing men until these uncertainties are
resolved by unmanned lunar probes, such as our forthcoming Ranger and
Surveyors. Their intelligence will determine the final design of the LEM's
Apparently, in 1964, there was still some uncertainty about the amount of
dust, even though the drawings in the NGM indicate that the artists thought
that the layers would not be very thick.
Don't have the time now to delve any further into this.
Hope this helps.
