What are water bears that ISRO may send to space with Axiom-4?
ISRO is sending Tardigrades, also called 'water bears', to space as part of an experiment, according to reports, though there is no official announcement yet. These are tiny, eight-legged animals which can only be seen through a microscope. "Tardigrada" means "slow stepper", referring to their sluggish, bear-like movement. The experiment will examine revival of dormant tardigrades in microgravity.
