Viking 1976: The Signal of Life on Mars Buried Under a Safe Conclusion
On July 20, 1976, Viking 1 landed in Chryse Planitia. On September 3, Viking 2 reached Utopia Planitia, about 6,400 kilometres away. Each lander carried biological experiments. One of them, Labeled Release, mixed Martian soil with a nutrient solution containing carbon-14 and measured radioactive gas. If microbes used the nutrients, they should release gas carrying the carbon label.
