Thats 1500 removed, which is a fraction of what is there to be analyzed.  Its great news, unless you need a gram of sample for your particular analysis.

Hi Mike - 

Great news - 1500 particles! I thought there were only a dozen!

did you see today's Hayabusa announcement?  It worked.

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.

      Current State of the Solar System : What is the size distribution and chemical composition of small bodies in the Solar System?  How does this compare to extra-solar systems?

      ISRU : What resources might be available to support human and robotic exploration of and human expansion into the solar system? 

      Hazards :  What is the internal structure and chemical composition of objects that might become an impact hazard to life on Earth?

 

While I am certainly capable of writing the entire section, this is probably not a good idea for at least two reasons.  First, I really do not know much about several of the bodies in our list, and I know much more about and am very m
