This is "hard sci fi," just as I like it. The title refers to a race to Mars, not a race of Martians (although it comes close to that, too). It's as much an example of "how to" on the cheap as it is a story. Benford is down on NASA (or the Federal government, or both), postulating a competition to Mars with a huge purse ($30 billion) as the way to get a human expedition there. That might be what it takes. Yet it's also a call for cooperation rather than competition. He shows the downside of human nature -- competitiveness, going for the gold, the potential for a breakdown of discipline in difficult situations. He advocates nuclear propulsion systems for planetary exploration, rather than today's chemical systems. He stresses how difficult planetary exploration will be -- especially the early stages, when improvisation and self-sufficiency are critical and thereby makes a case for on-the-spot decision-making rather than relying on orders from Mission Control. He also looks forward to life (past or present) on Mars. He was very creative in his depiction of what it could be like. In fact, this novel once again demonstrates to me the limitations of my creative abilities. Maybe I'm just intimidated, but I can't imagine writing a novel this well put together, this imaginative yet full of sophisticated technical detail. Heck, I wonder if I could even come up with a good idea for a "beginning, middle, and end." At any rate, it was an excellent adventure story, notwithstanding the fact that the end was predictable two-thirds of the way into the book. Benford put his lead characters through so many troubles (it actually got depressing at one point) in order to show the extent of danger and difficulties he expects planetary explorers to face that he left them only one way out. Arguably, that aspect of it could have been better written. And the way the threads came together in the end just fit too well.
Still, I enjoyed it immensely.
