[i]The variety of organic molecules that Curiosity recently discovered on the Red Planet included chlorobenzene. This molecule is created when carbon molecules burn with perchlorate, so scientists suspect that it could have been created when the soil samples were burnt, according to New Scientist. Researchers were inspired by this indirect evidence to dig a little deeper and find more evidence that the Viking landers could have found and then destroyed organics. In a [URL=https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2018JE005544]new study[/URL], published in June in the Journal of Geophysical Research: Planets, Melissa Guzman of the LATMOS research center in France, McKay and a handful of collaborators revisited the Viking lander data to see if anything was missed. This team found that the Viking landers also detected chlorobenzene, which the researchers said could have formed from burning organic material in the soil samples. Still, this is not proof that the Viking landers found organic molecules and then accidentally burned them, the researchers told New Scientist. Even the scientists who completed this investigation are divided.[/i]
