Just finished reading "A City On Mars - Can We Settle Space, Should We Settle Space, And Have We Really Thought This Through?' by Kelly and Zach Weinersmith, published by Penguin Press.
Now I'm of two minds with this book, which does look at the current level of technology currently available to explore and eventually colonize the Moon, Mars, and beyond. There are problems of sustainability, legalities, and basic human biology that are going to be resolved before outer space colonies are attempted and the Weinersmiths do a pretty good job at looking at these issues, BUT, the don't look at the work being done to resolve these issues. So it's a two-sided coin.
A light, fun read, but it's only part of the story.
Recommended.
Three Stars.
