Planetary space weather can be characterised by changes in the ambient planetary magnetic field and plasma populations around the planetary environment.
It is driven by changes in the energy carried by the solar wind from regions near the sun and the sun's atmosphere, analogous to space weather at Earth.
The effects of Space Weather on the Earth's environment are well documented, particularly in terms of risk to satellites, communications and ground-based systems such as electrical power grids and pipelines.
However, Space Weather on planets other than Earth are equally interesting and can be very dramatic.
Typically differences in the magnetic field and plasma environment at the other planets, as well as the distance of the planet from the sun drives different space weather effects as we move through the solar system.
The use of solar wind propagation models combined with solar observations allows us to obtain/predict the interplanetary conditions around each planet. In addition we have a wealth of in situ measurements from recent missions such as MEX, VEX, MESSENGER, and CASSINI. In this session we solicit papers on observations as well as the modeling of space weather and space weather condition in our solar system.
