Astrobiologist Dirk Schulze-Makuch raises a provocative theory that NASA's Viking landers may have unintentionally destroyed evidence of life on Mars nearly 50 years ago. This episode delves into the implications of this revelation, exploring how past experiments may have skewed our understanding of Martian biology. We also discuss NASA's upcoming 45-day simulated Mars mission, where astronauts will face the challenges of long-duration space travel. Join us as we navigate the ethical considerations of scientific exploration and the future of our quest for life beyond Earth.Sources:https://www.thebrighterside.news/post/nasa-may-have-accidentally-destroyed-life-on-mars-over-50-years-ago/https://www.marsdaily.com/reports/NASA_selects_crew_for_45_day_simulated_Mars_mission_in_Houston_999.htmlOutline:(00:00:00) Introduction(00:00:40) NASA may have accidentally destroyed life on Mars over 50 years ago(00:03:57) NASA selects crew for 45-day simulated Mars mission in Houston
