How do tardigrades survive in space without protection from radiation?

Tardigrades, often referred to as "water bears," are microscopic organisms renowned for their resilience in extreme conditions. Remarkably, they have been found to survive the harsh vacuum of space, where they endure not only the absence of atmosphere but also intense radiation levels. This ability is largely attributed to their unique biological mechanisms, such as anhydrobiosis and the production of protective proteins like Dsup. Understanding how tardigrades withstand such detrimental environments could provide crucial insights into astrobiology and the potential for life in space, as well as inform new strategies for protecting other organisms, including humans, from radiation exposure beyond Earth's atmosphere.
