We continue to explore the possibilities of life on Mars with Jaime Maussán. In recent decades, organisms have been discovered that can survive under the most extreme conditions on our own planet. They are known as extremophiles: living beings capable of surviving under extreme temperature conditions such as high acidity, salinity and radiation. An extraordinary example are the tardigrades or water bears, famous for having survived in space without oxygen or food and exposed to harmful cosmic radiation.
Such resilient life was unimaginable, 20 years ago. Moreover, the latest scientific discoveries raise serious questions about life in our solar system. Could there be living beings on the red planet?
