Errata for:

^a     The original read "fairness in the distribution of risks and benefits from the mission,"

^b     The original read "(many of whom are elected politicians with risks to their own careers possibly riding on these debates)."
Many risk management decision-makers are in appointed positions.

^c     The original read "Media play"

^d     The original read "the bases of NASA's decision to use plutonium"
I had failed to define the acronym as the "National Aeronautics and Space Administration," so the incorrect "National Aeronautical and Space Administration" was inserted in the editorial process.

^e     The original read "At over 5,600 kg, the 7 m high and 4 m wide orbiter and probe house eighteen instruments supporting 27 different investigations of the planet, its rings, its icy satellites, its magnetosphere, and Titan."
"Investigations" is NASA usage for these large-scale inductive studies, so the narrow, deductive meaning of "experiments" is misleading.

^f     The original read "First, the 5,655 kg mass of the Cassini (Saturn orbiter) and Huygens (Titan probe) combination and its navigational fuel, even without massive solar arrays, was already very close to the 5,760 kg launch limits of the largest American expendable launch vehicle (Titan IV/Centaur combination)."
The edited version omits the ˜350 kg of the Titan probe.

^g     The original read "and how their stances and central concerns were classified."
The substitution of "their author's stances" is ungrammatical -- it should have been "their authors' stances."

^h     The original read "In 1995, at the beginning of the study period, women made up 33 percent of Internet users in the United States and Canada (versus 7 percent of identifiable participants in the Cassini debate from April 1995 through March 1996). In 1999, at the end of the study period, women constituted 46 percent (versus 5 percent of Cassini discussion participants from April 1998 through March 1999)."
The substitution of "Internet uses" is a "typo" -- it should have been "Internet users."

ⁱ     The original read "another seven percent each were basic questions from Nostradamus fans or queries about the risk involved in the mission."
The removal of "each" implies that "basic questions from Nostradamus fans" and "queries about the risk" together added up to 7%, rather than 14%.

^j     The original read "while opponents were his critics."
The substitution of the singular "critic" for the plural "critics" is ungrammatical.

^k     The original read "Incorporated in that matrix were elements shown specifically to bear on perception of technological risk and arouse concern: dread, above all, and mistrust of public institutions responsible for informing the public about and protecting the public from hazardous technologies."
Removal of the colon created a sentence fragment.

^l     The original read "The source of political pressure may not be too apparent when decision-makers consider policy to manage a hazard."
Perhaps the substitution of "hazard policy management" was supposed to read "hazard management policy"?
