[en] The cosmic experiment on studying electromagnetic waves of very low frequency (VLF) (5kHz) in the Earth ionosphere, using two loop antennas, each 20 m in diameter, unfolded aboard the Progress-28 cargoship, and a reception of these waves aboard the Mir orbital station is carried out for the first time from the 26th to 28th of March, 1987. Characteristics of such antennas in the ionosphere are invesigated experimentally; VLF signal recording at distances from 1 to 40 km from the radiation is carried out. The reactance of the electrically small loop antenna in the ionospheric plasma under conditions of the experiment out (the antenna current does not exceed 80A) is established to have practically no difference from the reactance in free space. Analysis of experimental data obtained has shown that they agree satsfactorily with the results of calculations carried out on the basis of the linear theory for a cold plasma model

[en] Gamma-astronomical apparatuses plasced in the Cosmos-264 AES is discribed in short. The apparatuses are suggested to be placed at the Salut (USSR) and GRO (Gamma-Ray Observatory, USA) orbital stations. Flowsheets of gamma telescopes on the basis of spark chambers, Cherenkov and scintillation counters are given

[en] USSR orbital observatory ''Gamma'' planned to be launched in 1990 is described. General problems and observatory devices are presented. A diagram of basic telescope ''Gamma-1'' based on a spark chamber designed for detection of cosmic radiation with energy varying from 50 MeV to 5 GeV is presented. Telescope ''Disk'' designed for detection of electromagnetic radiation in the range from 0.1 to 8 MeV and X-ray telescope ''Pul'sar'' (the energy range from 3 keV to 25 keV) are described

[en] Results of the experimental studies of the dynamics of dust grains in the plasmas of an rf capacitive discharge and a dc glow discharge are presented. The dusty plasma of a dc glow discharge was investigated in both ground-based experiments and experiments carried out under microgravity conditions (on board the Mir space station). The pair correlation function, temperature, and diffusion coefficient of dust grains are measured in a wide range of the dusty-plasma parameters. Dimensionless parameters responsible for the microscopic transport of dust-grains in a gas-discharge plasma are determined. A nonintrusive diagnostic technique for determining the dust-grain charges and screening lengths under the assumption of screened interaction between the grains is proposed. This technique is used to estimate the surface potential of dust grains of different size in a gas-discharge plasma
