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."

Wow, guys. You didn't even need to read the article-
Actually, if you DO read the article (the one linked from the older slashdot post), you'll see that the airlock operator noticed the smell on the spacesuits of his fellow astronauts after each spacewalk.

It has a smell likely because we perceive sensations by association, in a relative manner. It's a cute (though somewhat frivolous) trick to simulate this association by engineering.
If you've ever been in an acoustically-isolated chamber, the silence is so overwhelming that it almost has its own sound. We're just not used to such near-perfect silence, so we try to interpret the novelty as a sound.
Similarly, if you put near-pure (95%) alcohol on your tongue, it will feel greasy because it is so dry that it dehydrates your tongue. The absence of water feels greasy.

It is from all the space dust that gets into the ships/station(s) by the air locks as well as carried in from suits/objects that are worn or used in space. That is how you smell space.
Also don't forget that any object that's brought outside of a spacecraft (like a spacesuit) is exposed to lots of ionizing radiation. When the object is brought back inside and the volatiles created on its surface allowed to mix with the internal atmosphere to create an odor, I can imagine there might be a characteristic 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.

I've read about this before, and I forget the details, but yeah, it's not actually space proper. It's really the smell of the space station. Something about the ionization of the metal walls when exposed to radiation, and there's no atmosphere to dissipate the charge into. Or something.

Just PR (Score:1)
Such news are made for improving PR but make no real sense for practical space activities. While a space station air certainly smells something, space gas is so dilute that no smelling may be perceived.
It is a bit like the sound or temperature of space, sometimes described for similar purposes. These cannot be perceived directly by normal people.
Re:Just PR (Score:5, Informative)
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.

Wouldn't the pressure differential guarantee that the *smell* stays outside? I mean it's not like space is going to "leak in" to the ISS, rather the ISS smell is going to go into space.

Could you imagine if humans lost the ability to smell smoke? A hell of a lot more of us(no pun intended) would burn to death in fires were it not for our ability to do so.
NASA simply realizes the importance of smell in many aspects, from diagnosis of a problem to the signaling of humans that a problem exists in the first place.

Well, thanks to you, at least I'm not ignorant anymore. Actually, this makes a lot of sense to me, now. I take a train to work every day. Sometimes, when the engineer has to brake real hard, the breaks give off that familiar "burning your brakes" smell. One time I mentioned it to the conductor, when he was checking my ticket. He quipped:
Oh, that's nothing . . . a total brake failure smells entirely different. And you would notice it immediately . . . because I would not be checking tickets!"
