Question
Was there any microbes discovered or any form of living material on mars discovered?
No, unfortunately we have not found any evidence of microbes either living or fossilized on Mars. The only samples we have to study in detail, of course, as the rare Mars meteorites. There have been no biochemical-based attempts at detection of microbial life on Mars since the Viking landers in 1976. One of the most provocative recent discoveries is the presence of methane in the martian atmosphere, which could be the product of microbial activity. But no experiments have been carried out yet to look for subsurface methane-producing microbes themselves.
