Yan,

Some thoughts. 

Smaller objects are also more numerous and more likely to collide withEarth.  There are several reasons to expect them to have differentproperties from larger objects, spin rate, porosity, composition, degreeof internal heating and differentiation.

I agree IR is necessary (don't forget IRTF), and currently we have IRspectra for <2% of known NEA.

Hello everyone -- Attachedplease find a rough, first-draft
of the outline for the Population Identification and
Characterization section of the roadmap.

I threw some ideas together that I thought were relevant,
but please feel free to shoot them down and change them.
Or, if you like some of the ideas, you can expand on them too.
The goal here is to have something reasonable by the time of the
SBAG meeting on August 3 and 4. The discussion about this
is scheduled for 8:45 am PDT on August 4.

Please feel free to edit the file itself, or send suggestions
around to the listserv.
Thanks for everyone's input!
