Formerly a hotshot NASA engineer, Graham Frederick has found his career in the toilet, literally. After losing a Mars probe and setting the building on fire, the only project available for him is to help design the commode for next space vehicle. How hard could it be to go to the bathroom in space? Bolt your toilet to the ceiling and try using it. Graham quickly learns that at 180 miles up and moving at 17,000 miles an hour, a toilet isn't just a toilet and nothing about space travel is mundane.
