Scientist Finds Something On Mars, But No One Believes Him

Could life have existed on Mars during the Viking era? In this video, the story centers on Gilbert Levin, an engineer who led a Viking-mission experiment in 1976 and has spent decades arguing that its results pointed to living microbes in Martian soil. The video describes how his findings were met with skepticism inside NASA, and how he later reexamined data from other probes to build his case. Along the way, it raises questions about water, ancient Martian landscapes, and why no follow-up life-detection instruments were sent. Press play to hear how one scientist’s stubborn claim has held up, or not, over more than forty years.
