Mysterious Odor from Russian Spacecraft Delays ISS Cargo Delivery

A Russian Progress cargo spacecraft docked at the International Space Station experienced an 'unexpected odor' upon hatch opening, prompting astronauts to temporarily close it. The odor, accompanied by small droplets, led to precautionary measures, but NASA confirmed the ISS air quality remains normal. The incident follows previous issues with Russian spacecraft, though no immediate link is established. The Progress spacecraft will remain docked for several months before departing with waste.
