Have you ever wondered if space has a smell?

Simply put, according to the experts, space stinks.

Some former astronauts have compared the odor to “seared steak,” “hot metal,” “welding fumes” and “gunpowder.” NASA has enlisted the help of London chemist Steve Pearce to recreate the smell, hoping it will help in training exercises.

Pearce recently recreated the smell of the Mir Space Station, which, he described as “sweaty feet and stale body odor, mix that odor with nail polish remover and gasoline" to Discovery.

"Add in a touch of vodka — because, after all, they were Russian astronauts aboard Mir — to that, and the end result, [Pearce] says was simply 'horrible,'" according to TIME.

“It certainly conveyed the sense that it wouldn’t have been nice to be trapped in Mir for too long,” he says.

According to TIME, Pearce goes on to say that:

[S]eared steak and hot metal actually fall in line with each other and “lead us to conclude that the sensation is caused by some high-energy vibrations in particles brought back inside which mix with the air” — with the recent discovery of ethyl formate in space’s dust particles and there’s a strong starting point for recreating the possibly sulfurous-like smell of space.
