3 November 1957

Laika, confined in her capsule prior to launch. She has no room to move, stand or turn around. No consideration was given to return her safely to Earth.

3 November 1957: Laika, a 3-year-old female dog, died in Earth orbit, confined in a small capsule named Sputnik 2. The cause of her death has been variously reported as euthanasia or oxygen starvation, but recent reports state that she died from overheating when the satellite’s cooling system failed.

Laika was a stray dog found on the streets of Moscow. She was trained to accept progressively smaller cages for up to 20 days at a time, and to eat a gelatinous food. She was placed in a centrifuge to expose her to high accelerations. Finally unable to move because of confinement, her normal bodily functions began to deteriorate.

Two days before being launched into orbit, Laika was placed inside her space capsule. The temperatures at the launch site were extremely cold.

Laika. “The more time passes, the more I’m sorry about it. We shouldn’t have done it. . . We did not learn enough from this mission to justify the death of the dog.”

Sputnik 2 was launched at 0230 UTC, 3 November 1957. During the launch Laika’s respiration increased to four times normal and her heart rate went up to 240 beats per minute. After reaching orbit, the capsule’s cooling system was unable to control the rising temperature, which soon reached 104 °F. (40 °C.). Telemetry indicated that the dog was under high stress. During the fourth orbit, Laika died.

The Soviet space capsule’s life support system was completely inadequate. The conditions which Laika was exposed to during her training and actual space flight were inhumane. There was no means to return her safely to Earth.

In 2008, Russia unveiled a statue of Laika at Star City.

Oleg Gazenko, one of the scientists responsible for her suffering and death said, “The more time passes, the more I’m sorry about it. We shouldn’t have done it. . . We did not learn enough from this mission to justify the death of the dog.”

  1. This is simply heart breaking. Thank you for bringing this to my attention (again), and thank you for the tribute to Laika.

  2. Much of the ‘Space Race’ back then was more about making impressions than about Science.

    1. Perhaps so, but it required Science. Virtually everything—technology, materials, processes—had to be invented. The first liquid-fueled rocket was launched 16 March 1926. The first rocket to reach space was launched 3 October 1942. The first artificial satellite was launched 4 October 1957. The first human in space was Yuri Gagarin, 12 April 1961. And on 20 July 1969, Neil Armstrong and Buzz Aldrin stood on the surface of the Moon. 43 years, 4 months and 5 days. To me, that is incredible.

  3. Perhaps Bryan Swopes should have volunteered for the Sputnik flight. Considering he is so understanding and supportive of the dogs plight.

  4. The thing that annoys me with posts such as this is that people are quite happy make to make the inference using the Internet and other marvellous innovation such as GPS , all made possible by the space race
