Yurij G. Shkuratov
Date and place of birth: 23 September 1952, Ivano-Frankovsk, Ukraine
Education: 1970-1975, Physics Department of the Kharkov State University.
Position: Head of Department "Remote Sensing of Planets" (Kharkov Astronomical
Observatory).
Titles: PhD (1980), Doctor of Sciences (1993), and Professor (1999)
Prizes:
The State Prize of Ukraine in the Field of Sciences
(1986).
The Prize of the National Academy of Sciences of Ukraine
(1997).
I am an author and co-author of more than 300 scientific works devoted
to studies of optical properties of the lunar surface as well as the surfaces
of other atmosphereless celestial bodies.
Main Results and Fields of interests:
I have obtained first images of the Moon for a new polarimetric parameter
which turned out to be the source of information about the average size
of lunar regolith particles.
I performed the numerous laboratory photometric and polarimetric measurements
of structure analogs of the lunar regolith (more than 1000 different samples)
which provided a reliable experimental basis for the verification and selection
of the theoretical models for the opposition effect and negative polarization.
I contributed to theoretical models of the light scattering by the surfaces
with complicated structure. In particular, I proposed the model of the
negative polarization of light based on the mechanism of the coherent backscatter
enhancement.
At present my scientific activity is in particular focused on studies
of optical properties of the lunar surface on the base of Clementine data.

Michail A. Kreslasky
Birth date: 18 November 1961
Education: 1995 - Ph.D. in Physics of the Solar
System from Main Astronomical Observatory of the National Academy
of Science of Ukraine.
1984 - M.S. in theoretical physics from
Kharkov State University
Position: since 1992 Senior research fellow,
Kharkov Astronomical Observatory, Kharkov, Ukraine. Several extended
research work periods in Brown University, Providence, USA
Main Results and Fields of interests:
Data from planetary missions is that I work with.
Understanding of nature of planets is that I work
for.
Working as a kind of interface between the data
and planetary geologist for years, I managed to find many new facts and
to warn against many wrong conclusions.
Major particular directions of my current
work are:
radiophysical properties of Venus surface (Magellan
data);
optical properties of surfaces of atmosphereles
bodies (Clementine data, astronomical observations, etc.);
small-scale topography of Mars (Mars Global Surveyor
data);
and, of course, implications of all these to geological
history of the palnets

Dmitrij G. Stankevich
Date and place of birth: May 31 1956, Kharkov,
Ukraine.
Education: 1973-1978, Kharkov state university,
Astronomy department.
Position: Senior research fellow, Asronomical
Observatory of Kharkov University

surface by the digital image processing methods" defended at Sternberg
Astronomical Institute (Moscow).
Prize: State Prize of Ukraine (1986)
I am an author and co-author of near 50 works.
Fields of interests:

astronomical and cosmic images (including Earth-based images of the Moon
and Mars; Phobos, Galileo and Clementine images);

scattering by the stochastic particles, surfaces and media (especially
of shadow-hiding effects). |

Larissa V. Starukhina
Being a solid state physisist among astronomers, she
applies ideas, methods and achievements of her science to astronomical
objects. She consideres the surfaces of as physical laboratories with vacuum
so pure that any terristrial laboratory may only dream about it.
She studies the effect of cosmic environment on the
spectra of particulate solid surfaces. To work with complicated multiscale
structure and composition characterictic of the surfaces of atmosphereless
celestial bodies, she developped the theoretical model of spectral albedo
proposed by Yurij Shkuratov (1987) to
different types of inhomogeneity of the surface and particles. She
applied the model to the various objects, e.g., lunar regolith, Phobos,
meteorites.
Her recent studies are devoted to the ice on the Moon.
As the first announcement about the Lunar Prospector finding appeared,
she asked: "Is it really ice that was found?" As she calculated, the amount
of ice reported can be explained by chemical trapping of hydrogen in regolith
particles: near the cold lunar poles the trapping can proceed to
saturation. |

Education: M.S. 1988-1993, Physics Department of the Kharkov State University.
Position: Yunior research fellow in Department "Remote Sensing of Planets"
(Kharkov Astronomical Observatory).

Scientific interests:
