Nasa’s Curiosity rover has detected organic molecules on Mars, including chemicals widely considered building blocks for the origin of life on Earth.
Five of the seven molecules identified in a dried lakebed near the equator had never previously been observed on the red planet. The analysis performed by the robotic rover cannot establish whether the organic compounds are linked to potential ancient life on Mars or were delivered by meteorites or formed through geological processes. However, the finding implies that if microbial life once thrived on Mars, chemical fingerprints should remain there today.
