An aging robotic geologist trawling for secrets in the dust of the Gale Crater had a meltdown. And it led to a one-off experiment that paid off big-time.<\/p>\n
How did scientists use a failure to unlock one of the Red Planet’s most significant discoveries<\/strong>?<\/p>\n NASA planted the Curiosity<\/em> rover on Mars more than a decade ago. Hopes were always high that it would deliver the groundbreaking data needed to advance eventual human life on the planet.<\/p>\n But Curiosity<\/em> is getting on in years. There’s only so much it can still deliver<\/strong> while it endures.<\/p>\n Designed to drill the cold, radiation-saturated surface, it was only a matter of time before supplies ran out.<\/p>\n NASA researchers had a difficult choice to make<\/strong> when onboard supplies ran low.<\/p>\n And a hard call that took years to make was made.<\/p>\n In a feat of engineering, scientists pivoted to a risky and untried experiment<\/strong>. But it meant the end of one of Curiosity<\/em>‘s functions entirely.<\/p>\n They turned to “wet chemistry” in an environment where organic preservation seems impossible. But it took the last remaining fluid cups to pull it off.<\/p>\n The dice were thrown, and the mechanical gamble paid off. The way we analyze alien dirt has been changed forever<\/strong>.<\/p>\n Mars’s Gale Crater wasn’t always a dust bowl. It was once a liquid water lake layered in mud<\/strong>. And NASA needed to inspect it.<\/p>\n Members of the rover\u2019s team had to decide the best possible spot for Curiosity<\/em> to drill a sample to test for organic material.<\/p>\n The rover only had two wet chemistry cups left. So the experiment had to count<\/strong>. They decided on a site and grabbed the clay mineral-containing sandstone sample.<\/p>\n The clay layers are able to preserve organic molecules. They suggested that water was not only present in the distant past, but that it disappeared and reappeared.<\/p>\n Energy options to sustain life<\/a> have also been found.<\/p>\n Curiosity<\/em> took more than six years<\/strong> after landing to reach the clay layer in the Glen Torridon region of Mount Sharp. But the wait was worth it.<\/p>\n Evidence of mudstones from ancient lakes was detected. Sandstone also showed up where moving water once trickled into the lakes.<\/p>\n The risk was a total triumph. Fragile material that endured billions of years of harsh radiation<\/strong> is now open to human scrutiny. <\/p>\n What NASA<\/a> found wasn’t standard Martian dust\u2014it was unprecedented. And also by accident, like how a cosmologist figured out a way to get to the planet in just 33 days<\/a>.<\/p>\n The new data showed 21 distinct carbon-containing molecules and seven organic compounds never seen on Mars before<\/a>.<\/p>\n Curiosity<\/em>\u2019s onboard chemical solvent unlocked two groundbreaking discoveries<\/strong>.<\/p>\n First, nitrogen heterocycles were found. These nitrogen-bearing molecules are critical. They are the fundamental precursors to RNA and DNA\u2014the literal building blocks of life.<\/p>\n Scientists identified benzothiophene next. The presence of this complex, sulfur-bearing molecule is highly significant<\/strong>.<\/p>\n It points to two fascinating possibilities: ancient Mars was either a bustling, active hydrothermal system, or the planet has a history of meteorite impacts.<\/p>\n Finding these organic molecules is not definitive proof of life on Mars<\/a>.<\/p>\n They could have appeared naturally from non-biological chemical reactions or carbon-rich meteorite impacts.<\/p>\n But it still confirms something profound. We now know beyond doubt that ancient Mars once held all the complex chemical keys to life<\/strong>. Could we find the fuels to ignite it?<\/p>\n","protected":false},"excerpt":{"rendered":" Something incredible has been hiding in Mars’s frozen deserts.
