Overview

• The Russian Progress 90 cargo spacecraft delivered three tons of supplies to the International Space Station but emitted an unusual odor upon docking.
• Astronauts sealed the hatch and activated air scrubbers after detecting the smell and observing floating droplets in the spacecraft.
• NASA attributed the odor to potential outgassing from materials inside the cargo ship, a phenomenon common in space environments.
• Air quality aboard the ISS returned to normal, and crew members resumed unpacking the supplies while wearing protective equipment as a precaution.
• The Progress 90 spacecraft will remain docked for six months before being loaded with waste and burned up during reentry into Earth's atmosphere.
