This 8-bit microcontroller
Linux in space is cool, but you know what's also cool? Linux running on hardware it simply should not be able to run on, such as a simple, 8-bit microcontroller, which one man actually made possible. He even used it to boot a full Ubuntu installation. This wins him the award for the most awesome/craziest/bored Linux nerd on the planet. And I want to give him a high-five.
