what does space smell like?
When you repressurize the airlock and get out of your suit, there is a distinct odor of ozone, a faint acrid smell, Jones told SPACE.com, adding that the smell is also similar to burnt gunpowder or the ozone smell of electrical equipment. It's not noticeable inside the suit. The suit smells like plastic inside.. The smell, he adds, only occurs on a shuttle or the space station after a spacewalk and is unmistakable to astronauts working with the spacesuits and equipment that was used in the vacuum of space. In those tight spaces, your nose gets right next to the fabric, Jones said.
