AbstractAbstract
[en] The present paper contains an outline of the method for a determination of the altitudes in the lunar mariginal zone from occultations of the stars by the Moon; and the limb charts of this zone were constructed from such altitudes. (Auth.)

AbstractAbstract
[en] On the basis of heliometric observations of the Moon carried out by the author between 1969-1975 a system of the coordinates of 32 lunar craters has been set up which is independent of the scale and orientation. The zero point of these coordinates has been fixed by the position of the crater Moesting A in accordance with Koziel. (Auth.)

AbstractAbstract
[en] Scanning electron microscopy has revealed the presence of potassium rich globules in the Luna-20 soil. Their size ranges from 1-5 microns and some of them appear to be hollow. They exhibit spherical, eliptical or disc-like shapes. Such objects have not been found in other lunar soils. (auth.)

AbstractAbstract
[en] Lithium contents for three Luna-24 samples are found to vary from 8 ppm to 10 ppm. Examination of Li values from various lunar missions show that more the KREEP content in a soil, the higher the Li value. (auth.)

AbstractAbstract
[en] Uranium content and distribution in Lunar rock fragments 0.4-0.9 mm in size from ''Lunar-16+ -20, -24'' stations were studied by the method of autoradiography. Uranium is almost absent in rock-forming minerals and is concentrated in some accessory mineral. Uranium content in microgabro fragments from ''Lunar-20 and -24'' equals (0.0n-n.0)16-6 g/g. Variations are not related to fragment representation. Radiogra-- phies of fragments from Lunar soil showed the uranium distribution from uniform (in glasses) to extremely nonuniform in some holocrystalline rocks. It was pointed out, that uranium micro distributions in Lunar and Earth (effusive and magmatic) rocks have common features. In both cases rock-forming minerals don't contain appreciable uranium amount in the form of isomorphic admixture; uranium is highly concentrated in some accessory minerais. The difference lies in tne absence of hydroxyl -containing secondary minerals, which are enriched with uranium on Earth, in Lunar rocks. ''Film'' uranium micromineralization, which occurs in rocks of the Earth along the boundaries of mineral grains is absent in Lunar rocks as well

AbstractAbstract
[en] A limitation to the exploration and use of space for scientific and industrial enterprise is the high cost of energy needed to overcome the earth's gravitational field in order to lift terrestrial materials into space. The reuseable space shuttle reduces the capital cost of ferrying such materials to near earth orbit but has little impact on the energy cost. The material requirements of servicing satellites in geosynchronous orbit and of exploring and colonizing the moon and nearby planets will be even more expensive in energy if all that material must be of terrestrial origin. One cost reducing alternative is to use materials already available in near earth space, that is on the moon and on asteroids with earth approaching orbits
