OT: Ames hosts SF luminaries for Mars terraforming debate

    I think this will be well-received, though it is OT.

    On Tuesday evening, March 30, NASA Ames will host an open-to-the-public 
debate on the wisdom of terraforming Mars. Participants include Kim Stanley 
Robinson, Greg Bear, Chris McKay (of course), and Sir Arthur C. Clarke (by 
telecon from Sri Lanka).
