Water bears, also called tardigrades, are the toughest creatures around.
Since a scientist first spotted them through a microscope in 1773, researchers have learned that water bears have survived every mass extinction on Earth and can tolerate all kinds of extremes, from radiation to low gravity to boiling and freezing temperatures. They can even enter an inanimate state to protect and preserve themselves in harsh conditions, then reanimate when their surroundings improve. On top of being extraordinary, these characteristics make tardigrades a prime candidate for space travel and research. But how do water bears do it?
In Water Bears in Space, launch into the fascinating world of water bears. Find out what these animals are, where to find them, and all about their tough traits. Explore the research and experiments scientists have conducted to better understand tardigrades and how they’re applying that knowledge to human health and deep-space travel. And dig into interviews from experts and young water bear fans about what makes these animals so unique. By the end, you’ll be able to conduct your own water bear experiments at home—or even keep one as a pet!
