How (and Why) SpaceX Will Colonize Mars

I'm way overdue on linking to this one, as I previously promised. I finished reading it at least a month ago, but I've been rather absent from my site. So here goes. 

This one is Part 3 of a four-part series from Tim Urban's site, Wait But Why. The first two parts were about Elon Musk, and Tesla. The third one, about SpaceX, is a doozy. Unlike my previous posts, I'm not even going to try to pick out the best parts. This post is absolutely epic. It's truly entertaining, informative, and really, really long. But it's so worth it. If you're not up for a long read, I recommend listening to the audio version that Urban posted on SoundCloud. It's a tidy 40,000 words, or 3 hours and 43 minutes long. 

Set aside some time to either read it, or listen to it. So great.
