Summary:
- In 1978, a Soviet nuclear-powered satellite, Cosmos 954, crashed into the Canadian North, scattering radioactive debris over a large area.
- The Canadian government launched a massive cleanup operation, known as "Operation Morning Light," to locate and remove the radioactive materials, which took several months and cost millions of dollars.
- The incident highlighted the potential dangers of space technology and the need for international cooperation and regulations to ensure the safe use of nuclear-powered satellites.
