Presentation Transcript
Workshop proposal to the Science Committee Solar Wind – Comet Surface Interaction : Workshop proposal to the Science Committee Solar Wind – Comet Surface Interaction
WS General Theme : WS General Theme Solar Wind interaction with comet surface material:
Dust lifting and transport mechanism
Water storage / release mechanism
How do they affect the active phase of comets?
What can be expected during the Rosetta mission? Haley Mars: Viking Lander –
Morning frost
Topics : Topics Understanding of dust lifting mechanisms on solar system bodies with low atmospheric pressure (Moon, Comets; possibly asteroids, Mars) from observations: Solar Wind, impact
Understanding of dust transport mechanisms based on modelling
Understanding of water storage and release mechanisms at material-vacuum boundaries Interactions in Cosmic and Atmospheric Particle Systems (ICAPS) / ESA Solar Wind caused dust-lifting from the Moon
(SMART-1/ SPEDE)
Topics (cont’d) : Topics (cont’d) Comet surface material composition and interaction with the Solar Wind
Induced chemistry in surface material
Composition of the cometary tail
Implications for cometary environment and cometary missions
Implications for the development of the Solar System Deep Impact, Stardust, Stardust-NExT
Timeliness and relevance to space science : Timeliness and relevance to space science Recent Stardust and Deep Impact missions
Chandrayan-1 Moon mission 2008
Rosetta mission phase preparation
Optimization of science return for Rosetta
Scientific Relevance : Scientific Relevance Knowledge of dust and water release mechanisms are the core questions of cometary research. They form the link between comet formation and solar system development as derived from cometary research
The workshop will also highlight outstanding problems and areas in which progress remains to be made before the Rosetta core mission 2014
WS Date & Structure : WS Date & Structure End 2007 - Late 2008
4.5 days, 4 talks/half day, plenary sessions, no splinter sessions, no working groups
Proposed Convenors : Proposed Convenors To be agreed with Rosetta science and mission team
