Martian gases pose life question  - BBC  Vittorio Formisano told a Dutch space conference methane and formaldehyde could signify biological activity. "[My observations] should not be taken as a statement that there is life on Mars today, because we need to go there, to drill the soil, take samples, and analyse them before possibly concluding that life is there," Professor Formisano said  "If you consider only methane which is observed in the Martian atmosphere, it would be 150 tonnes a year; if you consider formaldehyde then you have 2.5 million tonnes [of methane] per year, which is much more," he said. "And the correlation indicates the sources are in the soil, underground."
