Scientists have long speculated that there is organic salt on Mars, and NASA thinks that it has found a way to prove it.
The study published in the Journal of Geophysical Research: Planets, indirectly points to the presence of organic salts using data from the Sample Analysis at Mars (SAM) a portable chemistry lab inside the Curiosity rover.
In order to confirm what the data is suggesting, the lead author of the paper, James MT Lewis, has suggested using the Chemistry and Mineralogy (CheMin) instrument. The task is challenging because billions of years of radiation have erased or broken apart most organic matter.
