NASA's Curiosity rover analyzed the Mary Anning 3 rock and found 21 carbon-containing molecules, including seven never seen before on Mars, using the Sample Analysis at Mars (SAM) instrument with tetramethylammonium hydroxide (TMAH); the diverse organics support the idea that ancient Mars hosted life-friendly chemistry and environments capable of preserving organics for billions of years.
NASA's Curiosity rover, in a 2020 experiment using a TMAH chemical probe on the Mary Anning 3 rock in Gale crater, detected more than 20 organic molecules—including benzothiophene—showing preserved prebiotic chemistry on Mars. While not proof of past life, the findings suggest Mars had conditions favorable to life's building blocks billions of years ago. Scientists also note that returning Martian rocks to Earth could help confirm any signs of life, though the Mars Sample Return mission has been effectively canceled; future missions, including ESA's Rosalind Franklin rover planned for a late-2028 launch, will continue to drill deeper and search for organics on the red planet.
