What were the Soviet space dogs and why did the Soviet Union use dogs in space missions?
Soviet space dogs were stray animals used by the Soviet space program from 1951 to 1966 in suborbital and orbital flights to determine whether human spaceflight was feasible. Dogs were chosen because scientists believed they could endure long periods of inactivity and the physical stress of spaceflight better than other animals. Female dogs were preferred for their calmer temperament and because the capsule suits were built to work only with female anatomy.
What happened to Laika the Soviet space dog on Sputnik 2?
Laika launched into orbit aboard Sputnik 2 on the 3rd of November 1957 and became the first animal to orbit Earth. She died between five and seven hours into the flight from overheating and stress. The true cause of her death was withheld from the public until October 2002; Soviet officials had previously claimed she survived several days before her oxygen supply ran out.
Which Soviet space dogs were the first to survive orbital flight?
Belka and Strelka were the first living creatures to complete an orbital mission and return alive. They launched on the 19th of August 1960 aboard Korabl-Sputnik 2 and spent a full day in orbit. Their spacecraft also carried a grey rabbit, forty-two mice, two rats, flies, and several plants and fungi, all of which survived.
How were Soviet space dogs selected and trained for their missions?
The Soviet program selected stray dogs from Moscow's streets, reasoning that animals hardened by outdoor life would better endure spaceflight. Training included confinement in small boxes for up to twenty consecutive days, sessions in centrifuges simulating liftoff forces, and time in pressure chambers replicating altitude conditions. For orbital missions, a special jelly food made from breadcrumbs, powdered meat, and beef fat was prepared for the dogs.
What is the longest orbital spaceflight record held by a Soviet space dog?
The longest orbital mission ever flown by dogs was the twenty-two-day flight of Veterok and Ugolyok, launched on the 22nd of February 1966 aboard Kosmos 110 and recovered on the 16th of March. The record was not surpassed until the Soyuz 11 mission in June 1971. Both dogs showed cardiovascular deconditioning, weight loss, and muscle weakness after their return but recovered fully within several weeks.
How did Shutka and Kometa survive their failed Soviet space mission in Siberia?
Shutka and Kometa were launched on the 22nd of December 1960 on a mission intended to reach orbit, but the rocket's third stage malfunctioned and the spacecraft never got there. The capsule came down in Siberia buried in deep snow, and a self-destruct timer added urgency to the recovery effort. The dogs were heard barking when the capsule was opened on the second day and were wrapped in sheepskin coats before being flown to Moscow.
