Readability 6. Rating 6. Not well written and horribly edited (likely primarily an artifact of the Kindle version), so if just that probably warrants a "4" especially if one factors in the crazy that attaches itself to Mars (reading the letters at the end is fun but also a bit scary). But a wide ranging and detailed treatment of a topic I care a lot about, so definitely worthwhile. A bit sobering, especially if the impact of space travel on bones and reproduction is as severe as it seems and can't be counteracted in a manageable way.
