If there's life on Mars, it would be one of the most important discoveries of all time. It would mean life on Earth was not some special unique event - it would mean there's likely to be life throughout the Universe. In the first of two special programs on Mars, Horizon explores how the search for Martians is now hotting up, and why many scientists are becoming more and more convinced that life may have arisen on Mars, and that there may even be something living there now.
