Having completed our tour of the Solar System, we now turn to a\ndiscussion of the requirements for life, and where those requirements\nmight be satisfied elsewhere in the Solar System. Some - energy,\ncomplex chemistry, and liquid water - seem obvious, but they are not the\nonly possibilities or considerations. At the end, we will have a short\nlist of possible places to look, some expected, others surprising.\nRecorded live on 2009 Oct 29 in Room 1005 Smith Laboratory on the\nColumbus campus of The Ohio State University.
