Have you ever wondered what space smells like? If you’re like me, you probably haven’t. After all, how can you smell in a vacuum? Apparently, according to astronauts on the International Space Station (ISS), space does indeed have a smell; and a rather peculiar one at that.
As you know, we’ll never be able to directly smell space since there is no atmosphere. Though, after spacewalks, when astronauts reenter the ISS, their equipment and spacesuits retain the smell of space – much in the same your clothes retain the smell of smoke after you burn dinner.
So, what does space smell like? Astronauts have a hard time describing the smell, ISS Science Officer Don Pettit says, “The best description I can come up with is metallic; a rather pleasant sweet metallic sensation” Other descriptions include “hot metal”, and “seared steak”.
How are astronauts able to smell the final frontier? Megan Garber from the Atlantic writes, “It turns out that we, and more specifically our atmosphere, are the ones who give space its special spice. According to one researcher, the aroma astronauts inhale as they move their mass from space to station is the result of ‘high-energy vibrations in particles brought back inside which mix with the air.’”
The smell in our solar system is particularly pungent because it's rich in carbon and low in oxygen.
Now, you are probably wondering to yourself, ‘what does the rest of space smell like?’ Well, Oxygen-rich stars would have aromas reminiscent of a charcoal grill.
In interstellar space, the smells would be rather interesting. In dark pockets of the universe, molecular clouds full of tiny dust particles host a veritable smorgasbord of odors, ranging from the wafts of sweet sugar, all the way to the rotten egg stench of sulfur.
Oh, and astronauts from the Apollo 11 mission reportedly compared the stench of the moon to spent gunpowder.
And that is what space smells like.
