After opening the Progress spacecraft's hatch, the Roscosmos cosmonauts noticed an unexpected odour and observed small droplets.

Investigators are working to determine the source of the odour, which may have originated either from the Progress spacecraft or its vestibule connecting to the ISS. This incident follows a series of earlier issues with Russian spacecraft,

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.
