They monitored the weather and measured the composition of the soil and atmosphere. The landers also looked for signs of life. Their cameras saw no moving objects on the surface, and no growing plants. Chemical laboratories found no organic molecules in the soil. They did find chemical reactions like those produced by microorganisms on Earth. But scientists at the time…
