Revealed: What Space Smells Like In two words, not good By Kate Seamons, Newser Staff Posted Jul 29, 2012 2:10 PM CDT 27 comments Comments In this image from NASA television, Endeavour astronaut David Wolf floats above Earth. (AP Photo/NASA TV) (Newser) – Outer space may be soundless, but it's apparently not odorless. Life's Little Mysteries recently stumbled upon a 2009 interview with a NASA astronaut that's too good to not resurrect. In it, Kevin Ford spoke of picking up the weird odor while undertaking spacewalks. It's not something he could smell while embarking on them (the plastic odor of the spacesuit delights the nose then), but once back in the International Space Station, the smell is there: a metallic odor that Life's Little Mysteries describes as having the "aroma of seared steak, hot metal, and welding fumes."
