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 ...
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 ...

The survival of some microorganisms exposed to outer space has been studied using both simulated facilities and low Earth orbit exposures. Bacteria were some of the first organisms investigated, when in 1960 a Russian satellite carried Escherichia coli, Staphylococcus, and Enterobacter aerogenes into orbit. [1]
The timeline for returning the samples from Mars will depend on its funding Mars samples that could help us find alien life are stuck there until at least 2035, NASA says Skip to main content
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 ...
