Curiosity Rover Identifies 21 Organic Molecules in a Mars Sample — Including a Nitrogen Heterocycle Never Before Confirmed on the Planet
Scientists using NASA's Curiosity rover ran the first wet chemistry experiment ever attempted on another planet's surface, breaking apart organic matter sealed in a 2020 drill sample. Seven of the 21 carbon-bearing molecules they identified had never been confirmed on Mars, including a ring-shaped nitrogen compound with a structure resembling the building blocks of DNA and RNA.
