They couldn't have made it "Space Pizza"? Not too sure where they would get the cheese.
Hey, can they grow cheese with bacteria?
If I was an astronaut, I would happily give up all my changes of clothes, and all the water I would need for bathing if I could take cheese.
I guess my fellow astronauts wouldn't be too happy, but I would let them have some of my pizza.
I don't know how I would explain to them that the smell isn't the cheese...
