Kosmos 954 () was a reconnaissance satellite launched by the Soviet Union in 1977. A malfunction prevented safe separation of its onboard nuclear reactor; when the satellite reentered the Earth's atmosphere the following year, it scattered radioactive debris over northern Canada, some of the debris landing in the Great Slave Lake next to Fort Resolution, Northwest Territories.

This prompted an extensive multiyear cleanup operation known as Operation Morning Light. The Canadian government billed the Soviet Union for over 6 million Canadian dollars under the terms of the Outer Space Treaty, which obligates states for damages caused by their space objects. The USSR eventually paid 3 million Canadian dollars in compensation.

Launch and operation

The satellite was part of the Soviet Union's RORSAT programme, a series of reconnaissance satellites which observed ocean traffic, including surface vessels and nuclear submarines, using active radar.

The 28 January 1978 episode of Saturday Night Live featured a running gag about the radioactive debris from the crashed satellite having created giant, mutant lobsters heading for the U.S. east coast. The story concluded with them invading the television studio at the show's end.

In November of 2022, an eight-episode podcast series titled Operation Morning Light was released. It was hosted by Dëneze Nakehk'o, a veteran Yellowknife-based Dené broadcast journalist, and produced by Aliya Pabani, and discussed the impact and aftermath of Kosmos 954 on the land and peoples where the debris fell.
