How did the command and lunar modules dock and re-dock? Check out that video!
There's more on the command-service module over on my blog, Vintage Space at Popular Science, so check that out if you have more questions!
And there's loads of olde timey space to dig into on my blog, Vintage Space, too!
Like even older space? "Breaking the Chains of Gravity: the Story of Spaceflight Before NASA" is available now! You can order your copy on Amazon.
I'm also selling signed hardcover editions of my book on my website! (My site was recently hacked and I'm working on fixing it! If you want to order a signed copy, hold off and check back in a couple of week -- Sorry!!)
Connect on Facebook, Google+, Instagram, and Twitter as @astVintageSpace.
