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."
repapetilto writes "ISS Science Officer Don Pettit reports in his journal that outer space gives off a smell best described as "a rather pleasant sweet metallic sensation." Kind of odd considering smell is supposed to be due to volatilized chemical compounds."
niktemadur writes "The BBC reports that a French team of stellar seismologists, using the COROT Space Telescope, have converted stellar oscillations into sound patterns, a relatively new technique that, according to Professor Eric Michel of the Paris Observatory, is already giving researchers new insight into the inner workings of stars. The subtly pulsating, haunting sounds are very similar to artist Aphex Twin's minimalistic nineties album 'Selected Ambient Works, Vol. 2,' only stripping away what little melody it had and leaving just the beat. These and many more recordings from space can be accessed at the Jodrell Bank Center for Astrophysics website, also known as the Jodcast."
It turns out that space tastes like raspberries and not Tang or freeze-dried ice cream as one might suspect. Scientists at the Max Planck Institute for Radio Astronomy were searching for evidence of amino acids in space when they found ethyl formate, the chemical used in to make raspberry flavoring. The astronomers used the IRAM telescope in Spain to analyze electromagnetic radiation emitted by a hot and dense region of Sagittarius B2 that surrounds a newborn star. Astronomer Arnaud Belloche said, "It [ethyl formate] does happen to give raspberries their flavour, but there are many other molecules that are needed to make space raspberries."

As I have understood it, they're going to recreate what astronauts smell while in space, in other words, the inside of the shuttle and space suits, not space itself.
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.

I thought what you hear is the sound of yourself? You know, blood streaming and stuff. Ah, right, here we go [bbc.co.uk].
Good call. I was thinking of the immediate impression I got, the "blanket of silence" which he felt as a weight. Shortly afterward you start hearing your biology.
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.
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.
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.
Actually, astronauts have reported after spacewalks that their space suits collect a semi-metallic, sweet smell to them after they return to the shuttle/vehicle. Of course, depending upon the nature of the spacewalk, this could have been a collection of fine particles from welding and repairing a satellite, or exhaust that collected to the exterior of the shuttle during launch.
Here's a link to NASA.gov with an astronaut's recounting of smelling 'space residue' http://spaceflight.nasa.gov/station/crew/exp [nasa.gov]
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.
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.

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.
Too bad I just ran out of mod points. This would be my best guess as to why they're trying to recreate space smells. Particularly onboard the ISS, it's a really big deal if something inside the station ends up leaking or burning. And if you're operating something critical like an airlock and you start smelling something funny, that's definitely something to worry about. Here's an article from a couple years ago where the crew smelled something strange and ended up shutting down the entire ventilation sy
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!"
Perhaps you didn't understand the same but the article doesn't say that they try to recreate the smelll within a spacecraft, but the smell of *space*. Interplanetary or interstellar space is not empty but contains gas and dust particles. This medium is extraordinary dilute (typically 1-10^5 atoms/cm^3 and 99% of this is made of odorless hydrogen and helium). Despite this low concentration, accumulated over light-years this medium adds up to and makes structures like nebulae and dark clouds seen on teles
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.
So they want to recreate the smell of the international space station, a place where people work 12 hour days for 6 months on end with no showering facilities. Three guesses as to what that smells like, but you'll only need one.
wow, 20 comments, and not one of them a reference to Professor Hubert J. Farnsworth's Smelloscope? I'm impressed with everyone restraining their geekdom.
