Laika Space Dog
Laika was a Soviet space dog who became one of the first animals in space, and the first animal to orbit the Earth.
She was once a stray dog in the streets of Moscow and was originally named "Kudryavka" ("Little Curly")
She underwent training with two other dogs and was eventually selected to be the occupant of the Soviet spacecraft Sputnik 2 that was launched into outer space on November 3, 1957.
Laika died hours after the launch. It was first said she died of overheating. The truth was that she ran out of oxygen on day six.
On April 11, 2008, Russian officials unveiled a monument to Laika. It features a dog standing on top of a rocket.
