Just finished reading "Spacefarers - How Humans Will Settle the Moon, Mars, and Beyond" by Christopher Wanjeck, released by Harvard University Press.
WOW! What a difference a few months make! When I originally bought this book on Amazon back in January 2021, it was just a little more than $20 - now Amazon has it listed for just five bucks - if only I had waited I could have gotten a good book on space exploration for cheaper! Oh, well....
Former NASA writer Christopher Wanjek takes a through look at the problems humanity will encounter when it begins to give serious thought to colonizing the Solar System and why micro-gravity makes sex a bit of impractical possibility for heterosexual couples and gay men, but lesbians might fare better because of the mechanics behind the act. Wanjek also explores the pros and cons of why gravity wells are going to be required if humanity is going to thrive and grow in space, as well as the dangers of going beyond Earth orbit for any length of time even just to the moon and back. 
A through and thought provoking book.
Strongly recommended.
Five Stars.
