Hi Joe - 

and I will certainly contribute to science issues surrounding dust...

Dear SBAG Participants,
We need to write the text to go with the outline of the Science Issues section of the SBAG Roadmap before mid-December if we expect to have time to circulate a first draft through the group for comments and suggested changes.  I have attached my strategy for presenting these issues (as presented at the last SBAG workshop) and am asking for volunteers to write sections.  I have organized the section as a matrix of Bodies vs. Issues, but what that really means is that for each type of object in our list we will try to address each of the 5 science issues listed even if it means noting that study of that particular type of body is not relevant to that particular science issue. This will allow someone to easily search our document by issue as well as by type of object.  The list of bodies that require a short writeup (and a willing volunteer) are the following:
       Meteorites, IDPs and Returned Samples
       Short and Long-Period Comets
       Near Earth Objects (Apollos, Atens & Amors)
       Main Belt Asteroids (and comets)
       Phobos and Demos
       Large, Icy Satellites of the Giant Planets
       Irregular Satellites of the Giant Planets
       Trojan Asteroids
       Centaurs and Trans Neptunian Objects
       Pluto and Kuiper-Belt Objects
       Small Bodies in the Oort Cloud


The list of topical issues that I hope to see addressed in each writeup are:
       Solar System Origins: understanding the original composition of the nebula; the timing of events such as planet formation, differentiation and core formation and the chemical and isotopic evolution of the system  with time.
       Solar System Dynamics : understanding nebular collapse and transport; planetesimal accretion, migration and mutual interactions; evolution of the solar system through time and the cratering history of the solar system.
