Writing this series has been, for me, very therapeutic.  I’ve always been interested in space and space travel.  There’s still a lot more to talk about, for instance SSTOs (single stage to orbit) and why many think they’re the future of space travel.  Or the particular difficulties of landing on any planet with an atmosphere.  But overall I wanted this to be a fun little introduction to how space travel works and how it was done in the Apollo program.  Once I learned how it worked I started noticing how basically no movies or games (besides Kerbal Space Program do it justice.  I can’t tell you how many times I’ve noticed that most spaceships in movies or games don’t actually orbit anything, they just float around relatively motionless compared to whatever body they are near.  The International Space Station for its part is moving incredibly fast, with an orbital rate of about once every two hours.

Still it was fun to get this all out there and in one coherent place.  Thank you for taking the time to read and learn with me.
