Als jemand mit einem ziemlich schrecklichen Geruchssinn hatte ich noch nie an die Möglichkeit gedacht, dass das Vakuum des Weltraums einen Geruch haben könnte. Allerdings berichten Astronauten, dass ihre Anzüge und Ausrüstung einen Geruch haben, der auch nach der Rückkehr von Weltraumspaziergängen zurückbleibt.

    Einige Beschreibungen des Geruchs sind:

    – Ein starker metallischer Geruch

    – Schießpulver

    – Ozon

    – Süß riechender Schweißrauch

    – Gebratenes Steak

    – Eine Mischung aus Walnüssen und Motorradbremsbelägen

    Irgendwie weckte diese Vorstellung, dass ein Raum einen Duft hat, in mir den Wunsch, ihn eines Tages zu riechen, so eingeschränkt mein Geruchssinn auch sein mag.

    1. Scent is carried by air, and could not be carried in a vacuum. So anything the astronauts are smelling is coming from within their contained atmospheres such as their suits or the station itself.

    2. That isn’t space, that’s the smell of the equipment, perhaps chemical reactions from cosmic radiation etc.

      I have a few carbonaceous chondrite meteorites, including a 2019 Aguas Zarcas. When they are „fresh“, they have a very distinct „burnt“ smell. Mine is faded a lot over the years, but at first, it was very noticeable.

      I keep it in a little jewel case and open it up only when I want someone to smell it. It’s still noticeable, just not as strong as it used to me.

      It’s a burnt… something, but not anything easily recognizable.

    4. Fun unrelated but kind of is fact #1: Metals don’t smell. In order for something to have a smell it must release particles of itself into the air, and metals don’t do that. When you smell metal, what you’re actually smelling is something else on the metal having a reaction with the metal. An example of this is a penny, what you smell isn’t the penny itself, it’s the oil from hands reacting with the metal.

      Fun unrelated but kind of is fact #2: The searing of a steak is called the Maillard Reaction, and it’s a smell we evolved to find highly desirable.

      I have nothing to actually add to the topic, I just had to nerd out and info dump for a second. I would also like to smell space one day.

      Basically it’s the smell of the equipment, but specifically the smell is caused by the space environment’s effect on said equipment (atomic oxygen, radiation, etc)

    6. Everything is getting attacked by intense UV and atomic oxygen that is attacking everything exposed. It also ablates material, so you have atomically fine particles being oxidized, so basically burning it. This can be pretty intense.

      I have a few lasers.for cutting and engraving, the UV is surprisingly good at casting odors.

      I feel like nobody even bothered to click on the link based off these comments, which checks out for Reddit.

      Astronauts report this after a space walk when removing their helmets in the airlock. They are smelling the materials that make up the outside of their suits being degraded and off gassing volatile compounds after being exposed to radiation and solar wind.

      It’s not the smell inside their suits or the ISS itself that’s being described.

    8. People report metallic smell and taste when exposed to large doses of ionizing radiation here on Earth, so it’s likely the culprit in space, too.

    9. That’s not the smell of space, that is the smell of years of material degradation due to its exposure to the harsh environment of space like the alternating extreme heat and extreme cold along with other factors like ambient radiation. Maybe we never noticed this phenomena here on Earth because any equipment or vehicle is usually within a comfortable atmosphere. Maybe that atmosphere along with other elements like gravity and the ozone layer and Earth’s magnetic field are what are shielding everything within it. As you go to space, naturally you lose that protection.

      This is why ancient man would burn sacrifices on the alters. It was for our alien overlords who missed the smell of home.

      True story

    11. The scent maker mentioned early in the article actually ran [a kickstarter for “eu de space,”](
      https://www.kickstarter.com/projects/eaudespace/) letting people buy what they’d come up with for NASA in bottles like a cologne. 

      I got some. I’m glad I got to smell it but it immediately went into three layers of plastic bag and came out only rarely for curious guests until I eventually binned it in a move. It was *awful*. Like burning electronics in a busy airport restroom. In hindsight, it’s a shame that I didn’t find a science teacher or someone like that to give it to.

    12. StagedC0mbustion on

      Obviously the vacuum of space doesn’t have a smell bro there’s no molecules or atoms to inhale 😂

    13. Aren’t they just smelling the stuff on the spacecraft? Would explain why there’s a metallic smell

    14. I always thought (with no basis whatsoever) that the smells were their suits after having been in the most direct unfiltered sunlight imaginable

    15. spanksthemonkey on

      I want to huff Space.
      Not undog my helmet and have that *whoosh* when I attempt to inhale then have my rapidly freezing lungs outside my mouth.
      More like fill a bag with nothing during a space walk.

    16. There’s a fragrance out there called Eau de Space that is supposed to mimic what the astronauts smell. I purchased a small sample of it and found it really unpleasant! It definitely had all the notes you listed. A very complex scent but I got hit with the almost burnt steak and metallic notes first. I had to get it for the novelty. There is also Eau de Luna for the smell of the moon. I have not experienced that one, though.

    17. NASA Goddard Visitor Center has a display where you can smell the recreated scent of space. It smelled like burnt plastic to me. It’s a cool spot to check out if you’re located in the DC area.

      If you ever do work with a really high quality face mask with organic vapor filters you literally smell almost nothing.

      Then when you finally remove the mask you smell all kinds of weird smells you normally dont detect as your nose recalibrates. I bet something similar is going on here.

    19. oneinmanybillion on

      How would they know? They are constantly living in an environment designed by humans.

      Actual space is a near vacuum and they never ever venture into it?

      I don’t understand.

    20. Check this out https://eaudespace.com

      I bought both space and the moon but they smell very similar so I’d just buy one. But supposedly this is an accurate representation. Let’s just say, I think I’ll stay on Earth.

    21. The seared steak smell is slightly concerning. With all the radiation and small particles flying around I’d be worried it’s my own flesh

      >A lot of what the space station astronauts smell is likely the result of a sort of combustion. The space station is at a low enough altitude that it is still plowing through a faint atmosphere that contains oxygen. The station rams through this residual atmosphere to create a halo of excited oxygen around the station and this results in oxidation of materials, particularly those facing the ram direction of the station. I observed this when I was a graduate student and we discovered that mylar films that faced forward were all ‘etched’ away.

      >Undoubtedly the same process is occurring to the astronauts’ suits. So… probably another example of a form of ‘combustion.’

      I’m really into niche perfumery, and there are actually a few houses that make fragrances inspired by some of the smells you mentioned – metallic, ozone, gunpowder, welding fumes, etc.

      If you ever want to try something along those lines, check out **Alkemia’s Center of the Universe** and **Toskovat’s Inexcusable Evil**. They’re both pretty unconventional and might give you an idea of what “space” could smell like as a perfume.

    24. I don’t know if it still does, but the Space Shuttle Endeavour smelled that way when it was first put on exhibit in Los Angeles. So maybe you could smell it by visiting your nearest space hardware museum.

    25. I heard recently that it’s actually the small particles that shoot around space going through their brain and triggering certain neurons, which makes them see small flashes of light and also smell and taste metallic.
      As i understood these are the same particles that sometimes make it to earth and can be seen in cloud chambers.

      Its around here and they explain it more in depth

    26. I imagine cosmic radiation has a smell which this is possibly closer to what they are smelling, if not at least adjacent.

    27. A great opportunity for space agencies to market an aftershave. I mean , walnuts and motorcycle break pads! If you slap Ryan Gosling in the add , it’ll be a slam dunk this Christmas.

    28. Significant-Pace-521 on

      I mean the article list multiple smells from space that are possible…

    29. Bananananananrama on

      It’s the smell of whatever they are wearing interacting with the atmosphere they are inhabiting.

      **Metallic so space smells like blood? Khorne approves of this message.**

      A few years ago, there was a big hubbub in the fragrance world over Eau de Space, a perfume that NASA had supposedly developed to train their astronauts on how space would smell. I don’t know what I thought it would be, and honestly I could scarcely imagine the list of things they said it would smell like. When I finally got my bottle in the mail and tried it out, my opinion was that it smelled like a warm, wet diaper.

    32. IM_the_Mark on

      Okay, I just wanna know which one of you is out there huffin motorcycle break pads.
