On one level, there is an absolutely wonderful feel to the technology in this book. It really does feel to me like a slightly alternate history 1950s/60s, flying a trio of spacecraft to the red planet. It actually comes to the point of making me think: if this feels this real now, then why in the world haven’t we been to Mars yet. Bring on the meteor! (Not really. That would kill an awful lot of people.) You can really feel just how much research went into this book.
