Abstract
Translated articles cover the following topics: optimization of perturbation maneuver of solar-sail equipped spacecraft near the moon in a geocentric boost problem; model of particle fluxes and averaged energy spectra of solar cosmic rays; forecasting radiation conditions in interplanetary space; depth profiles of dielectric permeability of cryolithosphere of Mars; qualitative analysis of some methods of reducing the asteroid hazards for the earth; origin and current status of the problem of asteroid hazard; probability of asteroids colliding with Earth; description of control associated with placement of spacecraft in vicinity of L(sub 2) point of sun-Earth system via use of lunar gravity; optimal spatial transfer of a spacecraft between the lunar surface and artificial lunar satellite orbit; fly-back booster said to be most promising design for reusable aerospace system; and annual, semiannual, and seasonal variations of total ozone as deduced from TOMS data for the region of St. Petersburg.
