The Smell of Space
According to NASA scientists, space smells a lot like my uncle's workshop. One can detect hints of fried steak, hot metal, and the welding of a motorbike. They have hired Steven Pearce, a chemist and managing director of fragrance manufacturing company Omega Ingredients, to recreate the smell in a laboratory. NASA will use his research to help train potential astronauts. Steven said, "I did some work for an art exhibition in July, which was based entirely on smell, and one of the things I created was the smell of the inside of the Mir space station. NASA heard about it and contacted me to see if I could help them recreate the smell of space to help their astronauts."
You can smell underwater , well not you per se- there's a creature - a shrew or vole I think, or maybe muskrat. Anyways there is a Rat like creature that when underwater blows a small bubble of air out it's nose and then sucks it back (kinda the inverse of the spit/snot drop we've all done as kids). This allows it to smell the water and the scent of things in the water. It can actually track underwater by smell.
I think this story is referring to the locker room smell of human habitats in space, not actually the smell of space. But there are chemicals in space - it's not actually nothing nothing nothing and then planets and sun. In theory one could put atmosphere into a sample of 'vacuum' and try to sniff anything that volatilizes. But concentrations of matter are so low in space that it still seems kinda implausible.
So my point is, I don't know how to smell space, but I didn't know how smell underwater either until I watched the discovery channel.

Professor Hubert Farnsworth: Exactly. And now, Saturn.
Fry: Pine needles. Oh, man, this is great... hey, as long as you don't make me smell Uranus.
Leela: I don't get it.
Professor Hubert Farnsworth: I'm sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all.
Fry: Oh. What's it called now?
Professor Hubert Farnsworth: Urrectum. Here, let me locate it for you.
Fry: No, no, I, I think I'll just smell around a bit over here.

Actually, you're pretty ignorant. I fly for a living; and smells have saved my life. Knowing what "normal" smells like lets you recognize and analyze abnormal smells. Is that smell burning hydraulic fluid or misting hydraulic fluid? The difference is important, when you decide what to do about a hydraulic leak. (e.g. Do you turn off bleed air and pressurization and electrics because it's a fire, or do you isolate hydraulic systems so that you only loose one when the system fails completely). In other words, it's not a PR stunt, it's worthwhile training.
