Not Green Cheese Cobwebs' Cover Moon
Summer Session Kansan
Two National Aeronautics and Space Administration (NASA) scientists have added to the scientific controversy of whether the moon's surface is covered with a dust layer, just how deep it is, and whether it would support the weight of a landing vehicle.
They say it is estimated that it is from four inches to three feet thick and their contention supports one group of scientists who say that its porous cobweb-like structure would crumble underfoot like a fairy castle.
THE ESTIMATE was made in a paper, "Dust Bombardment of the Lunar Surface," presented at a Lunar Surface Materials Conference recently held in Boston. The authors
are Curtis W. McCracken of NASA's Goddard Space Flight Center and Maurice Dubin of NASA Headquarters. Mr. McCracken delivered the paper.
Controversy has raged for some time over the interpretation of radio, radar and infrared observations of the lunar surface. Some scientists have said that the lunar surface may be covered by deep layers of material into which any landing vehicle might well sink from sight.
However, McCracken and Dubin base their estimate of the thickness of the dust on data gained from spacecraft and ground observations of interplanetary dust particles. Most of these particles originate from
comets. The scientists said that available data on the flow of these particles show that the material accreted by the moon during the past 4.5 billion years amounts to approximately one gram per square centimeter if the flow has remained fairly constant. They believe it has. (A square centimeter is one sixth of a square inch.)

THESE PARTICLES travel at different speeds, depending on their size. Average speeds are approximately 6 miles a second for dust particles with dimensions of microns, 19 miles per second for particles with dimensions of millimeters, and 9 miles per second for bodies with dimensions of meters. These high speeds lead to hypervelocity impacts, events of explosive violence that result in destruction of both the particle and portion of the target, hence significant amounts of dust could be created.

GRAVITT'S FAST LAUNDRY SERVICE
However, whether the moon is gaining or losing mass as a result of these bombardments is still controversial. Some scientists feel that the moon is continually being eroded away by these impacts and has to expose new surface material. McCracken and Dubin suggest that the moon is gaining in mass because the impacting particles do not necessarily escape the moon's gravity and thus form a layer of dust and rubble on the surface.
They support Professor Thomas Gold and his associates at Cornell University, who under contract to NASA recently made measurements simulating the effect of radiations and fast-moving dust particles impacting on layers of loose particles.

THE CORNELL investigators examined a large number of terrestrial materials and compared these with the observed reflection coefficient of the lunar surface. One material had a cobweb-like structure and was composed of cement powder which has a chemical composition similar to that which might be expected on the lunar surface.
McCracken and Dubin say that such a structure, popularly referred to as "Fairy Castles," would largely retain the ejecta created by hypervelocity impacts of dust particles.
They said the low value for the accretion rate for the small particles is not adequate to produce large scale dust erosion or to form deep layers of dust on the moon.

Prof. Ralph N. Adams of the department of chemistry has been granted a Guggenheim fellowship for study and research beginning in February of 1964.
Guggenheim Study Grant Awarded to KU Chemist
Prof. Adams is one of 269 scholars, scientists and artists receiving one-year grants from the John Simon Guggenheim Memorial Foundation during the next year.
The foundation's fellowships are granted to "persons of the highest capacity for scholarly and scientific research" and are awarded to assist fellows in furthering developments and accomplishments in their fields by carrying on studies which they proposed to the foundation.
He will be studying and doing research on electron spin resonance, tentatively scheduled to be carried out in Zurich or Amsterdam.
Prof. Adams, who will be promoted to the rank of full professor July I, has conducted research supported by the Atomic Energy Commission, the U.S. Air Force, the American Chemical Society's Petroleum Research Fund, and the University. He
holds degrees from Rutgers University and Princeton University, and came to KU in 1955; he has been on leave the past semester.
Grumm Appointed Ass't. Dean of Faculties
John G. Grumm, associate professor of political science, will become assistant dean of faculties, effective Sept. 1.
He will work half-time with William J. Argersinger, associate dean of faculties for research, with particular regard to programs in the social sciences and the humanities.
Prof. Grumm has been a teacher here since 1956. He holds an A.B. degree from Occidental College and the M.A. and Ph.D. degrees from the University of California, where he also was a research associate in the Bureau of Public Administration and a teaching assistant.
