Correlation of the Apollo 12 descent film with the crew's comments during landing indicated that lunar dust first became apparent at about 30 meters from the surface and that from about 12 meters above to the actual touchdown the ground was almost completely obscured by the dust.

Because of both Apollo 11 and Apollo 12 landing experiences, studies were begun and discussions held about various aspects of lunar dust. An MSC management review in the latter part of January 1970 would include discussions of the basic mechanism of erosion during landing, the possibility of alleviating the effects of erosion on visibility, and an estimate of what could be expected at future lunar landing sites.
