Meteoroids 2004
Conference in London, Ontario, Canada
16-21 August, 2004


This conference will be the fifth in a series of meteoroid meetings which
have been held every few years since 1992, the last in Kiruna, Sweden in
2001. It will accommodate a broad range of meteoroid research ranging from
the dynamics, sources and distribution of these bodies, their chemistry and
their physical processes in the interplanetary medium and the Earths
atmosphere to their impact on space weather and their hazard to space
technology, and laboratory studies of meteorites, micrometeorites and
interplanetary dust. The high activity of the Leonid stream and the
appearance of the very bright comet, Hale-Bopp provided new data related to
meteoroids in recent years. Furthermore, the accurate measurement of orbits
for several recent meteorite falls and detailed observations and modeling
of their behaviour is providing a bridge between meteoritic material
studied on Earth and composition of Near Earth Asteroids. The discovery of
solid particles entering the solar system from interstellar space and
improved dust measuring capabilities on interplanetary spacecraft broaden
the range of experimental data. Current research further benefits from the
use of large aperture radar facilities to detect fainter meteors and the
general availability of high powered computing facilities to support
dynamical model calculations. Special emphasis of the discussion will be on
the observational sensitivities and biases that arise from the recent
application of different observation methods. With this theme we wish to
address both the dynamics of small bodies in the solar system as well as
the evolution of solid matter which provides a bridge to include aspect of
astrobiology and astromineralogy that currently is enabled through IR
astronomical obersvations. The meeting will be of interest to researchers
from astronomy, astrophysics, cosmochemistry, mineralogy and space physics.
