What Does Space Smell Like? — Planetary Radio April 24, 2009Posted by skywalking1 in Space.
Matt Kaplan of the Planetary Society interviewed me on April 20 on the fascinating subject of whether space has an odor. After repressurizing the airlock at the end of our spacewalks, Beamer and I noticed a faint, acrid smell coming from the fabric of our space suits. The odor was especially noticeable when our noses were close to the suit fabric or the walls of the airlock. Perhaps ozone generated by atomic oxygen impact while exposed to vacuum?
