and it always is with some of you "Mars enthusiasts".

It would be nice it Mars (or Venus) could be terraformed, it would be nice if the human organism could survive low gravity for extended periods of time, it would be nice if some solutions to Mars lack of magnetic field and high radiation were managable, it would be nice if there are not any pathgoens on Mars, it would be nice if the cost of transit were low... It would all be nice, but that don't make it so.

On the other hand, the plain fact is that in the recent past about every 1,000 years we have lost a coastal margin to impact mega-tsunami. Each of these areas is occupied today by about 100,000,000 people.

Now some in NASA are doing as near to nothing as they can get away in dealing with this hazard, and it is my hope that if they continue on this course they not be left in any position where they can endanger the public's safety.
