Mars Was Always Destined to Be a Desert

Turns out, Mars was never meant to be a lush, watery world like Earth. New research says the Red Planet had brief wet spells thanks to the sun, but its fate as a frozen desert was sealed from the start. Even with river valleys and lakebeds, Mars just couldn’t keep water around—the carbon got trapped in rocks and never made it back out. Basically, Mars had its moments, but habitability was always the exception, not the rule! #Science #Mars #SpaceScience
