Astronauts Track Massive Dust Clouds over Canada and the US from ISS in June 2025
While conducting microgravity experiments and preparing for the Ax-4 crew, ISS astronauts documented massive wildfire smoke clouds drifting over Canada and the U.S., highlighting the station’s role in monitoring Earth-based environmental events from orbit. The smoke, seen from space, resulted from wildfires that triggered evacuations and impacted...
