Cold, dry, and barren: Mars doesn't look like it could be a haven for life — at least not the kind humans are familiar with. Despite the Red Planet's appearance, scientists have wondered for decades about the possibility of microbial life inhabiting Mars in the distant past. Now a new study, based on data collected by NASA's Curiosity rover, is peeling back another layer of the mystery. For the first time, researchers measured the isotopic composition of carbon-rich minerals found in Gale Crater, a region laced with dried rivers and gullies and being explored by the rover.The findin...moregs Curiosity beamed millions of miles back to Earth were not optimistic, at least in terms of the potential for life above ground. "Our samples are not consistent with an ancient environment with life (biosphere) on the surface of Mars," said David Burtt, lead author of the study, in a statement, "although this does not rule out the possibility of an underground biosphere or a surface biosphere that began and ended before these carbonates formed."The new paper, published in the National Proceedings of the National Academy of Sciences on Monday, suggests two possible ways carbon-rich minerals could have formed at Gale crater: a series of alternating wet and dry periods at the site or salty-ice conditions. These two different ancient climate scenarios could be summed up as bleak and bleaker when it comes to supporting life.

In an environment that swings like a pendulum from wet to dry, the region would intermittently shift from more habitable to less habitable, said Jennifer Stern, a co-author. In frigid temperatures near the planet's equator, the environment would be hostile for living things because most water would be frozen and inaccessible for chemistry or biology."And what is there is extremely salty and unpleasant for life," she added in a statement.This isn't the first time scientists have theorized these possible climate scenarios for ancient Mars. Computer modeling of the planet, based on the presence of certain minerals and rock formations, have led scientists down this path before, but this is the first time they've had isotopic evidence from Martian rocks to bolster those ideas.

Scientists have sought life on Mars since the first spacecraft touched down on its surface in 1976. Mounting evidence from robotic explorers, especially from Curiosity and its twin Perseverance, has shown the Red Planet to have once been warmer and wetter, perhaps more than 3 billion years ago. The rover pair had a highly productive summer, including Perseverance's discovery of a spotted rock with the most compelling signs of ancient dead Martian life yet, though a sample would need to be shipped back to Earth for confirmation. A research team also recently published more evidence of a vast ocean of water below the planet’s surface. And where there's water on Earth, there's often life.Scientists are interested in Mars' carbon-rich rocks because they are like climate time cap...
