Observing and modeling the properties of small, primitive bodies in
the solar system whose origins lie beyond the water ice frost line [~5
AU] provides critical insight into the formation of the first Solar
System solids and establishes observational constraints for planetary
system formation. The characteristics of comet dust provide evidence
to validate the new, emerging picture of small body populations --
including comet families -- resulting from planetary migration in the
early Solar System. The IRTF has distinct advantages enabling cometary
science including the ability to conduct daytime observations of
apparitions, contemporaneous optical (MORIS), near- (SpeX) and
mid-infrared (BASS/MIRSI with the chopping secondary) on the same
night, temporal studies via-remote observing capability, and NASA
mission support. In particular we will highlight mid-infrared comet
science and discuss the import of continuing this opportunity as part
of future IRTF strategic plans and capabilities.
