Expedition Mars
Martin J. L. Turner’s Expedition Mars is an analysis of what a manned voyage to the red planet would take. It’s a very detailed analysis that includes a final hypothetical trip. It’s a very good and interesting book. The problem is that it’s not a very accessible book.
This is a very math heavy book full of calculations. There doesn’t even feel like an attempt at making it readable by someone not terribly knowledgeable in the field (ie me). It’s fine to make an apple instead of an orange, but if I don’t like apples (actually I do like real apples but that’s not the point), I’ll say it.
If you like a hardcore book on Mars exploration, I recommend it. But only if.
