How Tardigrades may help Astronauts?

Tardigrades, known for their extreme resilience to harsh conditions, possess a protein called Dsup (Damage Suppressor) that has garnered significant interest for its potential applications in human space travel. This unique protein has been shown to protect and repair DNA damaged by X-rays, a finding that could have profound implications for protecting astronauts from the harmful effects of cosmic radiation. Researchers have successfully transferred the Dsup protein to human cells, enhancing their resistance to radiation damage. This breakthrough suggests that incorporating Dsup into human cells could potentially improve their radio-tolerance, offering a protective advantage for astronauts during long-duration space missions where exposure to radiation is a major concern. However, it’s important to note that incorporating Dsup into humans would require genetic manipulations, which are not expected to be feasible in the near future. Moreover, the protein provides only partial protection, indicating that tardigrades likely employ additional strategies to shield themselves from radiation. This discovery not only highlights the incredible resilience of tardigrades but also opens up new avenues for research into enhancing human resistance to radiation, with possible applications in medical treatments, nuclear facility work, and the cultivation of crops in extreme environments such as Mars​.
