AB- Definitions of soil and various models of soil processes are
considered. It is noted that water is the driving force behind most
chemical reactions, the translocation of constituents, and the
intensity and resultant biochemical reactions within the soil profile.
Whereas on the moon there are more than 2200 known terrestrial
minerals, only about 100 have been identified on lunar regolith, and
most occur only in minor or trace quantities. Dominant minerals are
olivine, pyroxene, anorthite, and minor amounts of ilmenite. Many
crops, however, have shown a positive response to the incorporation of
plant residues and animal manures as organic fertilizer supplements and
it is suggested that human waste byproducts and plant residues could
provide essential nutrients deficient in lunar regolith. Compared to
other procedures such as hydrophonics and aerophonics, lunar soils used
for the growth of food crops would require low maintenance. Particle
size and weathering of lunar regolith are also discussed. (L.K.S.)|

AB- This work provides information on research and experimentation
concerning various aspects of food production in space and particularly
on the moon. Options for human settlement of the moon and Mars and
strategies for a lunar base are discussed. The lunar environment,
including the mineralogical and chemical properties of lunar regolith
are investigated and chemical and physical considerations for a
lunar-derived soil are considered. It is noted that biological
considerations for such a soil include controlled-environment crop
production, both hydroponic and lunar regolith-based; microorganisms
and the growth of higher plants in lunar-derived soils; and the role of
microbes to condition lunar regolith for plant cultivation. Current
research in the controlled ecological life support system (CELSS)
project is presented in detail and future research areas, such as the
growth of higher research plants in CELSS are considered. Optimum plant
and microbiological considerations for lunar derived soils are
examined. (L.K.S.)|

AB- Advanced cryogenic infrared (IR) space observatories, such as NASA's
Space Infrared Telescope Facility (SIRTF), have a variety of
requirements that require resolution at the system level prior to
allocation to subsystems. These requirements lead to system issues
unique to cryogenic IR observatories. Three of the most important
system issues are cryogenic life, optical sensitivity, and pointing and
control of the observatory. In addition, the design should include the
special demands of integrated observatory testing at cryogenic
temperatures. Finally, the observatory must be designed to maintain the
exclusion angles of the earth, sun, and moon, and to minimize heat
input from the sun and earth. Some key features of each of these system
issues are discussed. (Author)|
