re: NOT Too early
Do not count out books. They have been around for centuries and one does not need a thousand-dollar piece of equipement - that can become obsolete and useless in just a few years - to utilize them.
BTW, the book review is NOT reflective of the book. So what if the MER mission isn't done yet? I'm glad there is a print record of what has taken place so far on Mars. I can open a book any time I want and it doesn't even require electricity use to do so.
