Why fruit flies? Well, they’re cheap, breed fast, and share 60% of disease-related genes with humans. Plus, they don’t complain about the snack situation. That rocket reached 109 miles high—officially space by most definitions.
So while Laika got the fame, these six-legged astronauts were the real trailblazers. They proved life could survive launch and microgravity. And they didn’t even get a commemorative stamp. Typical.
The monkey business begins
After fruit flies came the monkeys. In 1947, a rhesus macaque named Albert II became the first primate in space—also on a V-2 rocket. Spoiler alert: he didn’t survive. Albert I’s flight failed earlier that year. It was a grim era for animal astronauts, and we owe them a massive apology.
By the 1950s, both the U.S. and USSR were running animal test flights like it was a bizarre pet show. Mice, rats, rabbits, and even two dogs named Dezik and Tsygan flew in 1951. They survived, which was a big deal back then. The Soviets were clearly dog people; the Americans leaned monkey.

I can only imagine the job interviews: “So, you’re comfortable with being strapped to a rocket? Great, you’re hired.” It’s a good thing animals can’t resign.
