The provided subject description identifies Layka as a city in China; however, there is no information regarding such a location in the source material or general geographical records. The source material pertains to a different entity of the same name.
Laika was a Soviet space dog and one of the first animals to travel into space. A stray mongrel from the streets of Moscow, she became the first animal to orbit the Earth when she flew aboard the Sputnik 2 spacecraft on November 3, 1957.
Because the technology required for atmospheric re-entry had not yet been developed at the time of the mission, Laika's survival was not expected. She died from overheating during the craft's fourth orbit.
