Perseverance finds potential biosignatures in Jezero Crater

NASA’s Perseverance rover has made one of its most intriguing discoveries yet in Jezero Crater. A rock sample called Sapphire Canyon, drilled from the Bright Angel formation, contains unusual chemical and mineral patterns that may be potential biosignatures.

We begin with remarks from Morgan Cable, research scientist at NASA’s Jet Propulsion Laboratory and co–deputy principal investigator of the PIXL instrument on Perseverance, in a video released alongside NASA’s September 10, 2025 announcement. Then, host Sarah Al-Ahmed speaks with Joel Hurowitz, associate professor of geosciences at Stony Brook University and deputy principal investigator of the PIXL instrument on Perseverance, who is also the lead author of the new Nature paper detailing the findings. Hurowitz explains how textures nicknamed "poppy seeds" and "leopard spots" connect organic carbon with minerals like vivianite and greigite, and why these could represent some of the most compelling evidence yet for ancient microbial life on Mars.

Finally, in this week’s What’s Up, Bruce Betts, The Planetary Society’s chief scientist, joins Sarah to explore earlier moments in the history of Mars exploration when tantalizing hints of life sparked scientific and public excitement.
