Plutonium Blurb
I'd welcome an accident where they decided to evacuate part of Florida.
First, I know there is really nothing to worry about. Second, as a 5th generation Fl native, I want to see all those people go. This is just anti-nuke hysteria from people who are ignorant. |

In the Titan 4B / Cassini launch, the greater immediate hazard from an on pad or early launch explosion would have been from the nitrogen tetroxide rather than the plutonium. I may be misremembering this, but ISTR reading after an NRO T4B blew up shortly after leaving the Cape that the launch rules said "don't go if there's a breeze toward land", just because of the nitrogen tetroxide + hydrazine hazard. Dunno if the same rule would be invoked for an RTG launch. |

That would have been a tough rule to meet, since Florida has a daily low altitude seabreeze coming off the Atlantic during most of the year. I wonder if the rule only applied to high altitude winds? - Ed Kyle |

See http://www.uswx.com/us/stn/?code=d&n=1000&stn=KTTS for a run of wind directions. Note that the Dir, Spd and Unit column labels seem to displaced one column to the right of where they should be. (Checking WeatherBug just now, the wind at the Shuttle facility is 10 mph from the SSW.) |

How, pray tell, would you operate a spacecraft that is at 39.5 times the
Earth's distance to the Sun? If you recall, the amount of sunlight available decreases by the inverse square of the object's distance to the Sun. So at Pluto there would only be .064% percent as much sunlight as there is at Earth's distance from the Sun. I think that as long as the RTG's are properly designed they are perfectly safe for use on spacecraft. Since the Pu is in a ceramic, contained within a housing, cigarettes are going to be much more deadly to your average Floridian than an RTG falling out of the sky.

Ya know, the Space Solar Power program was meant to also be a generic source for powering spacecraft, stations and habitats of all kinds. SSP was meant to provide the most basic infrastructure needed to colonize and explore space. They've chosen the easy route, the one that won't build a long term infrastructure. This is the same mistake made by the Apollo program. A one shot deal, no meaningful infrastructure. - Ed Kyle |

Do they still test RTG casings with tank guns? I saw a picture of a
test once, with an M1 firing into the iridium/carbon panel the cases are built from. |

but what are the locals going to do? They are going to beat it, that's what, hurricane evacuation style, abandoning their cars roadside when the gas stations run out as usual, etc.. A few will die during the evacuation, as they usally do, from accidents or fistfights or whatever. Funny, none of that happened after Three Mile Island, and that was right after the "China Syndrome" anti-nuke propaganda, and during a far more deadly threat. I think most Brevardians will say "oh well, if its gonna get me, its gonna get me." Floridians are a laid-back bunch, like New Orleans, most people don't bother to evacuate for hurricanes and that's after days of doom-and-gloom fear-mongering by the media and weather forecasters saying "80% chance its gonna hit you." New Horizons won't have that. There will be the usual news blurb about the RTG and the usual 15-second news bit about the inevitable protesters, followed by the newsgeek saying "but NASA says there's only once chance in 18 million" and so Joe Sixpack will ignore New Horizons. If it does blow, it will be over before Joe Sixpack can get up and go anyway. Brian |
