In Tucson I met the Vatican Observatory's Chris Corbally (seen here being prepped for audio) . . .
. . . and astrobiologist Neville Woolf, with whom I had a fun chat. I managed to keep my discussion with Woolf fairly seamless; other interviews were relatively clunky or burdened with self-inflicted pauses as I concentrated on pointedly ignoring the ever-present camera.
Television's an inherently illusory medium: the final product is a polished sliver of the actual process. Fortunately, as "investigator," my role was about as glamorous as I could expect; the bulk of my "technical" duties involved helping to carry a tripod.
