The Soviet Union launched the first animal to orbit the earth
into space—a dog nicknamed Laika—aboard the Sputnik 2
spacecraft.

Laika (above) part Siberian husky, lived as a stray on the
Moscow streets before being enlisted into the Soviet space
program.

Electrodes attached to her body provided scientists on the
ground with important information about the biological
effects of space travel. She died from overheating and
panic.
