- NASA's Curiosity rover discovered organic molecules on Mars, including chemicals considered building blocks for life on Earth.
- Five of seven identified molecules in a dried lakebed near Mars' equator were previously unknown on the planet.
- The analysis cannot determine if the compounds are linked to ancient life, delivered by meteorites, or formed geologically.
- Organic matter appears preserved for about 3.5 billion years, surviving harsh surface conditions like extreme cold and radiation.
- The findings suggest Mars once had conditions conducive to life, similar to early Earth, during a habitable window 3.7 to 4.1 billion years ago.
- Detected compounds include benzothiophene and hints of nitrogen-bearing organic compounds similar to DNA precursors, though not direct evidence of life.
- The discovery supports the potential for more detailed evidence from future missions, like ESA's Rosalind Franklin rover launching in 2028.
