Ancient Mars may have had an environment capable of harboring an underground world teeming with microscopic organisms, French scientists reported.

The findings provide a bleak view of the ways of the cosmos. Life — even simple life like microbes — “might actually commonly cause its own demise," said the study's lead author, Boris Sauterey, now a post-doctoral researcher at Sorbonne University. Early Mars’ presumably moist, warm climate, however, would have been jeopardized by so much hydrogen sucked out of the thin, carbon dioxide-rich atmosphere, Sauterey said. As temperatures plunged by nearly minus 400 degrees Fahrenheit , any organisms at or near the surface likely would have buried deeper in an attempt to survive.
Pahlevan led a separate recent study suggesting Mars was born wet with warm oceans lasting millions of years. The atmosphere would have been dense and mostly hydrogen back then, serving as a heat-trapping greenhouse gas that eventually was transported to higher altitudes and lost to space, his team concluded.

Underground microbes may have swarmed ancient MarsCAPE CANAVERAL, Fla. (AP) — Ancient Mars may have had an environment capable of harboring an underground world teeming with microscopic organisms, French scientists reported Monday. But if they existed, these simple life forms would have altered the atmosphere so profoundly that they triggered a Martian Ice Age and snuffed themselves out, the researchers concluded.
