Summary

Story summary

NASA's Curiosity rover detected long-chain alkanes—decane, undecane, and dodecane—making them the largest organic molecules found on Mars.
The findings were published in the journal Astrobiology.
The Cumberland mudstone's original abundance of these molecules may exceed what non-biological processes can explain.
The study notes that further analysis is needed to determine whether the molecules are biogenic and highlights the role of future Mars Sample Return missions for detailed laboratory analysis.
