Aug. 20, 1960: Back From Space, With Tails Wagging

1960: Belka and Strelka, a couple of stray mutts impressed into the Soviet space program, become the first living creatures to return alive from an orbital flight.
The Soviets had been using dogs for experimental high-altitude flights long before Belka (Russian for ?squirrel?) and Strelka (?Little Arrow?) lifted off from Baikonur on what would be a 16-orbit flight. Their safe return was by no means a certainty: Less than a month earlier, two other dogs were lost when the booster rocket meant to carry their Vostok spacecraft into orbit exploded on launch.
Then there was Laika, of course, the first living being to orbit the Earth. But Laika was sent into space on a one-way ticket; the Soviets knew beforehand that she wasn?t coming back.
It was the Americans, not the Soviets, who put the first animals into rocket-powered missiles to test the effects of rapid acceleration and weightlessness on a living organism. Albert, a rhesus monkey, was the first to go, launched into suborbital space on June 11, 1948, aboard a V-2 Blossom rocket. He did not survive.
The Soviets began experimenting with rabbits, mice and rats before switching to dogs in the early 1950s. In general, the Soviets were successful at bringing their dogs home safely, and several of them made multiple flights. One plucky pooch, Snowflake, made at total of six flights during 1959 and 1960.
In selecting their animals, the Soviets preferred females (owing to their temperaments and the ease of waste elimination) and strays (which were considered hardier and more adaptable than pampered house pets).
The dogs went through rigorous training to get them ready to fly. Because the dog would be immobile throughout the flight ? in a specially constructed safety module inside the capsule ? she was confined in gradually smaller boxes for days on end, and trained to sit still for long periods of time. The animal grew accustomed to wearing a space suit and was placed in flight simulators and centrifuges that prepared her for space flight.
Belka and Strelka did not go into space unaccompanied. With them onboard Sputnik 5 were 40 mice, a couple of rats and some plants. All were unharmed by their one-day voyage.
Strelka, in fact, went on to become a mother. One of her puppies was presented to President Kennedy?s daughter, Caroline, as a gift from the Soviet Union. When Caroline?s dog produced her own litter, JFK got a few laughs by referring to them as ?pupniks.?
Eight months after Belka and Strelka returned to Earth, cosmonaut Yuri Gagarin became the first biped to orbit the Earth and return safely.
