    That new cat smell often reported with docked Dragon capsules might just be the smell of trouble. [LINK]

    SAGE III is super sensitive. Because it needs unpolluted conditions to operate optimally, it includes contamination sensors that keep an eye on whether and how its environment might be messing up its measurements. Those sensors soon came in handy: 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 outgassingā€”releasing molecules beyond the expected, and perhaps the acceptable, levels. And those molecules were sticking to SAGE.

    Whoops. Maybe just let the Dragons smell like dragons?
