Query: Spreading Life to Mars

After the excellent but technical "Case for Mars" Zubrin positions himself as a great fiction writer with "First Landing". The people in "First Landing" are real, with their flaws and quirks. This is not Star trek, there are no warp drives and teleporters. Life on Mars is hard and dirty, but eventually the people prevail due to their own strength and ingenuity.Going to Mars is not a frivolous idea. Mars is within reach, and it must be done. If we shy from this challenge, ignorance and terrorists will prevail over America, over that country which in distant past landed its people on the Moon.
