Many of us stuck on Earth wish we could join (at least temporarily) the Expedition 1 crew aboard the International Space Station (ISS). Floating effortlessly from module to module, looking down on Earth from a breathtaking height of 350 kilometers…. It’s a dream come true for innumerable space lovers. But be careful what you wish for! Living on the Space Station also means hard work, cramped quarters, and… what’s that smell? Probably more outgassing from a scientific experiment or, worse yet, a crewmate.
