You're comment made me smile. Only because I clicked the link, saw the page and thought, "who designed this?". My next thought was, "well, most of the space related sites look like this, so maybe it fits well with what that community expects".
Google Chrome: Ctr +, Ctr +, Ctr +
Honestly, the same thing I had to do with Hacker News. Font is damn too small, for me at least.
I view webpages at 120% by default. I used to love small fonts, now I don't know what I was thinking and instead prefer the browser default of 16px.
In Chrome: Settings, Under the Hood, Customize Fonts. Set the "Minimum font size" to something comfortable.
Firefox: Options, Content, click the Advanced tab under "Colors and Fonts". Choose a minimum font size that's comfortable.
I didn't even realize I was squinting at the tiny letters until I read this comment. Thanks for pointing it out, future me's eyes are grateful.
If your browser is not setup to show 11px as readable I suggest you change something locally.

Medium-grey text on light-gray background doesn't help either.
Seriously! This must be the worst website I've encountered in a long time. Despite the inspiring content in the article, I leave with a mixed experience. Just goes to show how much design matters.
