that NASA were going to raise funding by offering to take advertising into space, i can think of nothing worse than an orbiting McDonalds or Coke logo shining down at me 24 hours a day. A friend once had a theory (after seeing a shot of the inside of the international space station) that it was just a giant hydroponics lab for growing the CIA's cannabis (you know the stuff that makes eggs look like brains - thanks Bill!) and that was how NASA was going to fund a journey to Mars.
