The selection and characterization of the Phobos-Soil landing sites
Basilevsky, A. T.; Shingareva, T. V.
This paper shortly describes the selection technique for the landing sites of the Phobos-Soil spacecraft, the characteristics of the Phobos relief, the history of choosing the potential landing sites in the process of working on the project, and the suggestions to shift the landing sites to the region recently imaged by the Mars Express spacecraft…
Dissipation of buoyancy waves and turbulence in the atmosphere of venus
Izakov, M. N.
The turbulent energy dissipation rate and the coefficients of turbulent diffusion and viscosity caused by breaking buoyancy waves (BWs) have been calculated. From the comparison of these values with other data, the contribution of BWs to the generation of turbulence has been determined. The comparison confirms the validity of the turbulence charac…
Venus Express: The presence of turbulence in the mesosphere of venus is confirmed
Izakov, M. N.
Among the numerous and valuable results obtained from the Venus Express spacecraft, information from several instruments suggests that turbulence is present in the mesosphere. In this paper, the results of these experiments are interpreted with the use of the available data on turbulence in planetary atmospheres. Accounting for turbulence is neces…
On the thermal history of Saturn's satellites Titan and Enceladus
Dorofeeva, V. A.; Ruskol, E. L.
The thermal histories of two geologically active satellites of Saturn—Titan and Enceladus—are discussed. During the Cassini mission, it was found that there are both nitrogen-containing compounds—NH3 and N2-and CO2 and CH4 in the water plumes of Enceladus; at that, ammonia is the prevailing form. This ma…
Rosetta—one comet rendezvous and two asteroid fly-bys
Schulz, R.
One of the two planetary cornerstone missions of the European Space Agency is the Rosetta mission to comet 67P/Churyumov-Gerasimenko. Rosetta is a rendezvous mission with a comet nucleus, which combines an Orbiter with a Lander. It will monitor the evolution of the comet nucleus and the coma as a function of increasing and decreasing solar flux in…
Venus express: Highlights of the nominal mission
Fedorov, A.; Barabash, S.; Sauvaud, J. -A. +18 more
Venus Express is the first European (ESA) mission to the planet Venus. Its main science goal is to carry out a global survey of the atmosphere, the plasma environment, and the surface of Venus from orbit. The payload consists of seven experiments. It includes a powerful suite of remote sensing imagers and spectrometers, instruments for in-situ inv…
Astrometric and photometric observations of solar system bodies with Pulkovo Observatory's automatic mirror astrograph ZA-320M
Gorshanov, D. L.; Kouprianov, V. V.; Devyatkin, A. V. +3 more
A brief description of the process of astrometric and photometric observations and their processing by an automatic complex, based on Pulkovo Observatory’s ZA-320M telescope, is presented. The basic results of astrometric and photometric observations of Solar System bodies obtained during 1997-2007 are given. They include, in particular, the resul…
The retrieval of altitude profiles of the Martian aerosol microphysical characteristics from the limb measurements of the Mars Express OMEGA spectrometer
Bibring, J. -P.; Vasilyev, A. V.; Mayorov, B. S.
Parameterization of the spectral dependence of the optical characteristics of Martian aerosols has been proposed for processing the results of measurements of outgoing radiation. A method for retrieving the altitude profiles of the microphysical characteristics of Martian aerosols from the limb spectrometry of the OMEGA instrument of the Mars Expr…
A study of the bound water, water ice, and frost distribution over the Martian surface: Treatment and correcting of the data of observations with the OMEGA spectrometer onboard Mars Express
Fedorova, A. A.; Kuzmin, R. O.; Rodin, A. V. +3 more
The results of the analysis of the spectral observations of Mars carried out with the OMEGA spectrometer onboard the Mars Express spacecraft are presented. The data from one of the spectrometer’s channels working in the near-IR spectral range (0.93-2.69 µm) were analyzed. This range includes the characteristic absorption bands of both condensed wa…
