They have not found direct evidence of life on Mars yet, but NASA's Perseverance rover discovered a rock sample in 2024 from Mars' Jezero Crater that contains potential biosignatures. These biosignatures could be substances or structures that might have a biological origin, indicating possible ancient microbial life on Mars. The sample, named "Sapphire Canyon," was taken from a rock called "Cheyava Falls" in an ancient riverbed. While this finding is the closest scientists have come to discovering life on Mars, it is not definitive proof. The confirmation requires bringing the samples back to Earth for further detailed analysis. The discovery is considered groundbreaking and a significant step forward in understanding Mars' history and habitability.
