A groundbreaking discovery has been made on Mars, with the largest organic molecules ever found on the planet shedding new light on the possibility of life on the Red Planet.
How the discovery was made
The discovery was made possible by NASA’s Curiosity rover, which has been exploring Gale Crater on Mars since 2012. The rover’s Sample Analysis at Mars (SAM) mini-lab was used to analyze the chemical composition of a rock sample, known as Cumberland rock, which dates back an impressive 3.7 billion years.
- The SAM mini-lab is cofunded by the French space agency CNES and is an integral part of the Curiosity rover.
- The rover has been providing scientists with valuable insights into the Martian environment and geological history.
The significance of the discovery
The Cumberland rock sample yielded compounds made up of 10, 11, and 12 carbon atoms, which are thought to be parts of fatty acids preserved in the sample. Fatty acids are organic molecules that on Earth are considered the “building blocks of life” due to their role in forming cell membranes and performing various biological functions.
- Living organisms produce fatty acids to aid in the formation of cell membranes and perform other essential functions.
- Fatty acids can also be produced through chemical reactions triggered by geological processes, without the presence of life.
Implications for the search for life on Mars
The discovery of large organic molecules on Mars has significant implications for the search for life on the planet. While there is currently no definitive proof of life on Mars, the presence of these molecules suggests that the conditions for life may have existed on the planet in the past.
“Our study proves that, even today, by analyzing Mars samples we could detect chemical signatures of past life, if it ever existed on Mars,”
Carilone Freissient, the lead study author and research scientist at CNRS.
Smaller organic molecules have been discovered on Mars before, but this discovery highlights the possibility that organic chemistry advanced to a level required for the origin of life on Mars.
Implications for future missions to Mars
The discovery of large organic molecules on Mars bodes well for plans to bring samples from the Red Planet to Earth, where they can be analyzed with the most sophisticated instruments available.
