I have a deeper appreciation for the amount of work that goes into an operation like that after having bought [Kerbal Space Program](https://kerbalspaceprogram.com/) and its mobile companion [Simple Rockets](http://jundroo.com/project/simplerockets/).

Engaging with those simulations also makes watching movies like "Apollo 13" into a whole new experience, too.

Congratulations to everyone involved, and I can't wait to see what they do next.
