Monte Davis on Livingston's Space Show

Monte Davis, historian, science writer and all-around good guy writes;
I'll be on David Livingston's Space Show tomorrow, starting at noon Pacific time. We'd be happy to hear from you during the show; details for calling or IM/ICQ'ing in during the show are here.

The main topic is "mythbusting" about where we currently are (and aren't) in space -- the real technological, economic, and political constraints, and what seem to me the shortcomings of most space advocacy.

But I expect we'll also get around to possible alternatives to chemical rocketry: nuclear, laser launch, and... you guessed it.

For a preview of the angle I'm coming from, go to here and see the four-part "Thinking Clearly About Space" series under the "more top stories/recent headlines" tabs.
Beats the snot out of listening to A Prairie Home Companion.
