Mars-1 was the first spacecraft launched to Mars in 1962, [266] but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of ...
Microbes could be living on Mars by obtaining energy from chemical imbalances between minerals in a process called chemolithotrophy which means “eating rock.” [41] However, in this process only a very tiny amount of carbon is involved — much less than was found at Yellowknife Bay. [42] [43]
In 1975, NASA's Viking program launched two identical landers to the surface of Mars, each carrying scientific instruments. Their biological experiments included gas chromatography–mass spectrometry to identify the components of Martian soil, analysis of gas exchange with the Martian environment, pyrolytic release of radioactive 14 C to check if carbon fixation occurred, and labelled release ...

A new study makes the case that descendants of long-ago life forms may still be living on the Red Planet
Experiments of the adaption of microbes in space have yielded unpredictable results. While sometimes the microorganism may weaken, they can also increase in their disease-causing potency. [1] It is possible to classify these microorganisms into two groups, the human-borne and the extremophiles.
The Perseverance rover has found evidence in a leopard-spotted rock that could suggest microbial life once existed on Mars billions of years ago, NASA said. NASA’s Perseverance rover may have ...
In 1976 two identical Viking program landers each carried four types of biological experiments to the surface of Mars. The first successful Mars landers, Viking 1 and Viking 2, then carried out experiments to look for biosignatures of microbial life on Mars. The landers each used a robotic arm to pick up and place soil samples into sealed test ...
