, an international team of scientists led by the Technical University of Munich examined the Martian meteorite Tissint, which fell near the village of Tissint, Morocco, on 18 July 2011, with pieces of the meteorite found as far as approximately 50 kilometers from the village.
As seen on Earth, organic molecules are analogous to life, but the study notes that abiotic organic chemistry, non-biological processes, have been observed"in other Martian meteorites."
There are only two interesting things about life on Mars. 1. Did life on earth and Mars derive from a common source? 2. Are there dormant viruses on Mars that can infect earth cells?
