That's an excellent suggestion. We will add a 6th Category for Astrobiology to the Issues section of each report. I had subsumed that into Origins, but breaking it out expliccitly is a good idea.

Joe et al.,
Regarding the list of issues to be addressed in that science section, it may also be interesting to address the astrobiological relevance of each category of bodies, and highlight some of these objects that have been suggested to shelter habitable conditions at some point during their history, and possibly now. Dawn is a few years away from testing whether or not Ceres is a "warm icy satellite." Several studies have also suggested that the large KBOs and Centaurs could have sheltered a deep ocean for extended periods of time. Testing the relevance of these models could be a major driver for the exploration of these objects during the next decade.
Thanks for your attention.

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?
