NASA ar putea avea deja indicii despre viața pe Marte

NASA's Perseverance rover has collected a rock sample from Mars that may indicate past microbial life. The sample, named Sapphire Canyon, shows distinctive markings potentially linked to microbial activity. However, confirming this requires bringing the sample back to Earth, a plan that is still under development due to technical and financial challenges. The Mars Sample Return program has faced reevaluation, and while there are discussions about simpler recovery methods, no final strategy has been announced. Meanwhile, China plans to launch its own Mars sample return mission by 2028, which could yield different samples. The scientific community remains cautious, emphasizing that only Earth-based analysis can definitively determine the origins of the markings found on the rock.
