It smells like burned steak!
We can't actually smell space due to the lack of oxygen up there.
But a burned steak odor is what comes off of the astronaut's space-suit according to astronauts after they have spent some time outside of their spacecraft.
Popular Science has a recent article explaining what space smells like and why the smell is "like a burned steak".
The article confirms an astronaut is not just longing for a home-cooked meal when he/she smells the burned beef after a space-walk.
Cheers!
