Fifty years after Viking 1 landed on Mars (July 20, 1976), the mission delivered the first soil analysis and iconic imagery from Chryse Planitia, lasting well beyond its 90-day plan thanks to an RTG, until a late-1982 battery-charge change inadvertently disabled the lander’s high-gain antenna and ended contact in 1982, with the VLMM terminated in 1983.
Astrobiologist Dirk Schulze-Makuch suggests that NASA's Viking 1 lander may have inadvertently killed potential microbial life on Mars by introducing too much water during its experiments in 1976. He argues that NASA's assumption that Martian life would have similar requirements to Earth life might have been flawed, as Martian microbes could have adapted to extract water from the atmosphere using salts. This hypothesis highlights the need to consider unique environmental adaptations when searching for extraterrestrial life.
