Just curious...are Mars and Venus considered to be in the "habitable zone" of our Sun ??...i know they don't have watertoday but the certainly in the case of Mars it seems that water did appear on the surface at one time....
Frank Drake gave a very good talk tonight at the Kepler science conference and I listened in at connect.arc.nasa.gov/keplerHighlights:- Interesting take on the Fermi paradox: he thinks that ET would find it more efficient to explore interstellar space through radio and telescopes rather than expend lots of energy trying to get craft going up to near light speed. Thus he thinks that there wouldn't be any "alien visitors".- The window for an alien civilization trying to find us (or us trying to find a given alien civilization) could be short indeed as our technology is getting more efficient and our signals aren't leaking out as much. Other civilizations could follow courses similar to ours.

Mars yes Venus no, I thought. The earth is close to the inner edge of the habitable zone.
