A recent analysis of the Sapphire Canyon mudstone core, drilled by NASA’s Perseverance rover in July 2024, adds new and convincing evidence to the ongoing search for life on Mars.
The study describes minerals and textures that – on Earth – are often linked to microbial activity. At the same time, the authors stress that some unknown, nonbiological chemistry could also explain the signals.
“This finding by Perseverance is the closest we have ever come to discovering life on Mars. The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars,” said acting NASA Administrator Sean Duffy.
