You don't have to stick your head under the water to smell the Ocean. All you have to do is stand next to it. And no, you can't roll down your window in space to get a whiff of it. Like the link said, the smell was stuck to thier space suits. When they got back into the shuttle and took them off they could smell it. I've been told my clothes smelled like cigarette smoke days after they were put in the laundry hamper.
I think that's probably the smell of their rocket ship... I don't see how space, which is literally nothingness, can have a smell to it.
I'm not even going to google anything right now; just shooting from the hip. You have stars burning and blowing up all over the place. Planets colliding. Comets buzzing all around and leaving trails behind them. Asteroid belts grinding along. And then there's all the people smoking pot/brewing absinthe (Thanx Nyxx). How then could space not have a smell?
Personally it could smell like roses or like a junkie's ass. I'm never going to find out for myself.. So what's the point in worrying about it?
Astronauts only smell what they've been eating inside those space helmets, so Tang and space-food sticks
