Formisano measured formaldehyde at 130 parts per billion.

To astrobiologists it was an incredible claim. It means huge amounts of methane must be produced on Mars. (While methane lasts for hundreds of years in the atmosphere, formaldehyde lasts for only 7.5 hours.) "It requires that 2.5 million tons of methane are produced a year," said Formisano.

"There are three possible scenarios to explain the quantities: chemistry at the surface, caused by solar radiation; chemistry deep in the planet, caused by geothermal or hydrothermal activity; or life," he added.
