Snapshot of the cover of "A City on Mars," including a flattering
blurb by Andy Weir. A mountainous red landscape with a black sky,
with a tiny person and vehicle in the foreground. One mountain is
covered with a glass hemisphere with barely-visible trees within, and
a schematic tunnel extending downward out of view to a subterranean habitat.

My current book is A City On Mars, by the Weinersmiths. The short-short summary is that space travel is really hard, and that people who are optimistic about a permanent human presence in space have mostly not thought about the problem hard enough.
