NASA’s Curiosity rover has made a significant discovery on Mars by identifying organic molecules, which are considered building blocks of life. This discovery was made through a groundbreaking chemistry experiment, the first of its kind conducted on another planet. While these molecules are not definitive proof of past life on Mars, they suggest that crucial elements for life have been preserved on the planet’s surface for over 3 billion years. During that time, Mars is believed to have had large bodies of liquid water, essential for life. The experiment, conducted in 2020, revealed more than 20 organic molecules, including benzothiophene, which is also found in meteorites and asteroids. This finding supports the idea that Mars was once a habitable world, similar to Earth when life began here. However, to confirm the presence of past life, scientists suggest bringing Martian rocks back to Earth for further study.
