The Space Organism That Could Change Alien Life Research | Alyssa Carson

Paglalarawan

Alyssa Carson breaks down the strange organisms that can survive conditions humans never could, from tardigrades exposed outside the International Space Station to a black fungus found near Chernobyl that appears to feed on radiation. Danny and Alyssa talk about why that kind of biology could matter for deep space travel, including the possibility of using organisms to help shield astronauts from cosmic rays. The conversation also turns to Mars, where the question is not only whether life ever existed, but whether we could prove it without contaminating the evidence ourselves. Alyssa explains why early Mars may have been far more habitable than it is today, why rovers move so slowly, and why planetary protection becomes a serious problem the moment humans start touching rocks on another planet.
