O.o

According NASA, outer space smells similar to fried steak and hot metal.

Those are the two aromas that come up most when the space agency debriefs astronauts returned from missions. One particular astronaut described space as smelling like a motorcycle being welded.

Now NASA has commissioned Steve Pearce, a chemist, to recreate these surprising odors so that astronauts in training can get a sense of the conditions they will face in the great beyond. “We have already produced the smell of fried steak, but hot metal is proving more difficult,” Pearce explained.
