NASA’s Perseverance rover has discovered complex macromolecular carbon on the surface of a rock at the Bright Angel site in Mars’ Jezero Crater. This is the shallowest detection of organic matter on Mars to date. The carbon was found using SHERLOC, a UV Raman spectrometer on the rover, which identified a spectroscopic signature similar to terrestrial kerogen, a substance usually of biological origin on Earth. However, scientists are cautious about labeling it as such because its origin on Mars could be either biotic or abiotic. This discovery is significant as it could provide insights into past life or chemical processes on Mars, but further analysis, possibly involving returning samples to Earth, is needed to determine its true nature.
QUESTION: How might discovering the origin of this Martian carbon impact our understanding of life beyond Earth?
A martian rock has lots of carbon on it, and it’s not clear why
