    Cosmos — Carl Sagan

    Still the best single argument for why any of this matters, and it leaves the arithmetic in. For a reader who wants the science, not just the awe.

    Pale Blue Dot — Carl Sagan

    The case for leaving Earth, written by someone unsentimental about how hard that is. Suits readers who want the argument rather than the poster.

    Project Hail Mary — Andy Weir

    Hard-SF problem solving in The Martian's key — for anyone who liked the engineering more than the peril. The only novel on this list.
