A Russian supply ship brought food and equipment to the International Space Station. Cosmonauts detected a strange smell. They closed a hatch and turned on air purifiers. The odor went away quickly. The crew accessed the supplies.

Upon opening the hatch of the newly docked resupply ship, Russian cosmonauts detected a strong, unfamiliar smell and observed small droplets.

NASA and Roscosmos immediately activated air-scrubbing systems across the station. The U.S. segment deployed the Trace Contaminant Control Subassembly (TCCS), while Russian segments used additional purification systems.
