Space travel might seem awesome, but it’s actually really tough on the human body. Without Earth’s gravity, muscles get weaker, bones lose density, and simple movements become hard work. For a trip to Mars, which could take years, keeping astronauts strong is a major puzzle. The surprising answer? Tiny mice are helping scientists crack the code.
Mice: The Tiny Teachers of Space Fitness
Mice share many biological similarities with humans, making them perfect stand-ins for space experiments. On the International Space Station (ISS), mice have been studied in varied gravity conditions. Researchers monitor their muscles, bones, and movements to see how the body reacts over short periods. This is
