There are now beyond the identification of potential habitats of more numerous, perhaps the first concreteevidence of life forms on Mars:
Considerable attention for the discovery of possible organic residues in several Martian meteorites has beendone on Earth. Of this class of meteorites only a handful are known. They have been millions of years agoprobably thrown by a single impact event on Mars into space and have reached the earth. We know that they need to represent rocks from Mars, because the isotopic composition of trapped gas bubbles in the Martianatmosphere, as measured by local probes, exactly. The said organic radicals are trapped in the rock in the dark filaments Hunderstelmillimeter area, which look similar to how some rod-like terrestrial bacteria. It soon becamedoubtful that they are biological products, because they are much smaller than the corresponding referenceobjects on the earth, which is why they have been sometimes referred to as "nanobacteria". However, this viewMartian structures not only look like bacteria, they also contain polycyclic aromatic hydrocarbons (PAH, PAH) and magnetite in the carbonate matrix, as can be formed by biological activity . A counter-evidencecould be at least so far not compete, so that there is still further the possibility that we have given in this formfossils from Mars.
