Program provides capability of assessing weight above given structural station planes for inert and variable masses for any selected loading condition. Output is produced that yeilds weight data concentrated on and/or cantilevered from stations along Saturn 5 vehicle's verticle axis. Input data availability limits program's function to vertical structures.

Six amino acids (glycine, alanine, aspartic acid, glutamic acid, serine, and threonine) obtained by hydrolysis of extracts have been quantitatively determined in ten collections of fines from five Apollo missions. Although the amounts found, 7-45 ng/g, are small, the lunar amino acid/carbon ratios are comparable to those of the carbonaceous chondrites, Murchison and Murray, as analyzed by the same procedures. Since both the ratios of amino acid to carbon, and the four or five most common types of proteinous amino acid found, are comparable for the two extraterrestrial sources despite different cosmophysical histories of the moon and meteorites, common cosmochemical processes are suggested.

The processes of hydrogen stripping, agglutination and impact comminution, acting upon a regolith containing both indigenous and solar wind-implanted carbon, provide a quantitative explanation for the relationship between carbon abundance and isotopic composition observed for Apollo 16 soils.
