Which insects were the first to be sent into space?

Which insects were the first to be sent into space?

• A. Bees
• B. Mice
• C. Fruit flies
• D. Rats

Answer: (C)

Early space biology used tiny, rapidly breeding organisms to learn how life endures space conditions. Fruit flies were ideal because they reproduce quickly and their genetics are well understood, so scientists could detect whether high-altitude radiation and microgravity caused heritable changes. In 1947, fruit flies were launched aboard a V-2 rocket, becoming the first living beings to reach space. They survived the flight, and some showed mutations, demonstrating that spaceflight can affect biology in a detectable way. Bees are insects but were not the earliest to go to space, and rats or mice are mammals, not insects, so they don’t fit as the first insects. The record shows fruit flies as the first insects sent into space.
