TomcatViP said:Regarding then the Dragon vehicle, it seems that they found an outgassing problem during the docking phase on the ISS:
Source:When the next three Dragons docked at the Space Station, over the following months, SAGE experienced unexplained spikes in contamination. Something on these Dragons was outgassing—releasing molecules beyond the expected, and perhaps the acceptable, levels. And those molecules were sticking to SAGE.
Outgassing, in earthly terms, is what makes a new car smell like a new car. “There are volatile chemicals in those new materials that migrate through the material to the surface," says Alan Tribble, author of Fundamentals of Contamination Control. You’re smelling escaped seat ingredients, in other words.
