Writing, KSP (why else am I here?), Spaceflight (crewed and robotic), Astrobiology and the search for habitable exoplanets, Interplanetary travel and colonization, Interstellar travel, and watching or reading plenty of science fiction and fantasy.
Today is the 1 year anniversary of when I first joined the KSP forums, at the time, I only had the demo, and now, a year later, I have the full game, and it's awesome!
