According to NASA scientists, “space” smells of “fried steak” or of “burning metal”, or even “motorbile welding.”

In spite of the strange odors reported by astronauts, the eccentric amatuer astronomer Sir Patrick Moore says “There is nothing in space and nothingness cannot really have a smell.” Known for his ”poorly fitting blazers and extremely high trouser line”, Sir Patrick Moore is a former president of the British Astronomical Association, as well as former president and co-founder of the astute Society for Polar Astronomy and author of over 70 books.

“We have already produced the smell of fried steak, but hot metal is more difficult.” Moore says. ”We think it’s a high energy vibration in the molecule and that’s what we’re trying to add to it now.” Strange stuff… and strange space stinkiness…
