A Few Facts About Russian Space Dogs

Why did Russian scientists choose dogs?

  • Scientist believed that dogs could remain inactive for a prolonged period of time
  • Females could urinate without disturbing their position
  • Stray dogs were better acquainted with harsh conditions and hence could cope with space flights

Russia used female dogs for testing the viability of manned sub-orbital and orbital flights, Laika, the first living creature to make an orbital flight, became the most popular dog.

  • Same dogs were used more than once

  • Two dogs Smelaya and Bolik escaped from the experiment centre before their scheduled journey but Smelaya later returned and successfully made her flight

  • On July 22, 1951, Tsygan (Gypsy) and Dezik made their maiden sub-orbital flight and returned after reaching and altitude of 110km

  • On August 19, 1960, Belka and Strelka accompanied with mice and rats started their journey, remained in orbit for one day and successfully returned after 17 orbits around the Earth

  • Russia’s first 3D computer-animation movie Belka and Strelka: Star Dogs is named after this pair

  • Strelka had six puppies with Pushka, another dog who was trained to make space flight but never made one. One of Strelka’s puppies, Pushinka, was presented to the U.S President John F. Kennedy’s daughter Caroline Kennedy.

  • Damka and Krasavka became famous after their miraculous escape. Due to multiple machine failures, the rocket crashed after attaining a peak altitude of 214 km and the ejection seat failed to operate. After a one day long search, the capsule was found buried deep in the snow, but there was no sign of life. But, on the second day scientists returned to find barking dogs trapped inside the capsule.

  • Verterok and Ugolyok were the last pair who made it to space and made history by spending the longest time in space. On February 22, 1966, they started their flight in a Kosmos 110 spacecraft and remained in space for 22 days before safely returning.


Among all these dogs, Laika enjoys a special place in the minds of animal lovers all over the world, mainly because people think that Russians did injustice to Laika by putting the helpless animal on a space flight that was never meant to return. There are many unanswered questions regarding the last hours of Laika inside that ill-fated flight, and one can only hope that it wasn’t painful.
