L'odore dello spazio 25.07.12

Secondo gli astronauti lo spazio ha un odore metallico e dolciastro.

The best description I can come up with is metallic; a rather pleasant sweet metallic sensation. It reminded me of my college summers where I labored for many hours with an arc welding torch repairing heavy equipment for a small logging outfit. It reminded me of pleasant sweet smelling welding fumes. That is the smell of space.
