While NASA’s Curiosity rover continues to crawl over the reddish, radiation-blasted wasteland, organic geochemist James M.T. Lewis is in search of salts through its Sample Analysis at Mars (SAM) lab and Chemistry and Mineralogy Instrument (CheMin) on board. He led a study recently published in “On Earth, life is one of the processes that can concentrate organic salts,” Lewis tells SYFY WIRE. “Any process on Mars that concentrates organic salts and organic matter is really interesting to us. We're saying that organic salts are a really good explanation for a lot of SAM data, but we ar...

Organic salts on Mars hint at ancient microbial life on the Red Planet If the finding is confirmed, it would be some strong evidence pointing at ancient life on Mars. Reset NASA has announced that certain organic salts are “likely present” on Mars. While this doesn’t necessarily mean that the salts were created by life on Mars (other processes can also produce the substances), it definitely makes it much likelier. This look back at a dune that NASA’s Curiosity Mars rover drove across was taken by the rover’s Mast Camera (Mastcam) on Feb. 9, 2014 – the 538th Martian day, or sol, of...

Share A NASA team has found that organic salts are likely present on Mars. Like shards of ancient pottery, these salts are the chemical remnants of organic compounds, such as those previously detected by NASA’s Curiosity rover. Organic compounds and salts on Mars could have formed by geologic processes or be remnants of ancient microbial life. Besides adding more evidence to the idea that there once was organic matter on Mars, directly detecting organic salts would also support modern-day Martian habitability, given that on Earth, some organisms can use organic salts, such as oxalates and a...

Organic salts detected on Mars: NASA Monday, May 24, 2021 IWK Bureau Organic salts are likely present on Mars, a NASA team has found, and their detection may provide evidence that life once existed on the Red Planet. A study, published in the Journal of Geophysical Research: Planets, found that organic salts, such as iron, calcium, and magnesium oxalates and acetates, may be widespread in Martian surface sediments. These salts are the chemical remnants of organic compounds. Organic compounds and salts on Mars could have formed by geologic processes or be remnants of ancient mi...
