Although it's a bit of a divergence from "seared steak," "hot metal, "sulfur," and "welding fumes"--all other ways space explorers have described the smell of the great unknown--it fits in with the general theme of: unpleasantly pungent.
Researches say the distinctive smells have to do with the arrangement of particles as they move from areas without gravity to the controlled environments of spacecrafts. The aromas are the result of "high-energy vibrations in particles brought back inside which mix with the air," one researcher told The Atlantic.
Space also has an effect on astronauts' sense of smell, making it easier to smell dank scents, as astronaut Chris Hadfield describes in this video:
