Arthur T Knackerbracket has processed the following story:

NASA's Perseverance Mars rover has detected its highest concentrations yet of organic molecules, in a potential signal of ancient microbes that scientists are eager to confirm when the rock samples are eventually brought to Earth.

While organic matter has been found on the Red Planet before, the new discovery is seen as especially promising because it came from an area where sediment and salts were deposited into a lake—conditions where life could have arisen.

"It is very fair to say that these are going to be, these already are, the most valuable rock samples that have ever been collected," David Shuster, a Perseverance return sample scientist, told reporters during a briefing.

Organic molecules— compounds made primarily of carbon that usually include hydrogen and oxygen, but also at times other elements—are not always created by biological processes.

Further analysis and conclusions will have to wait for the Mars Sample Return mission—a collaboration between NASA and the European Space Agency (ESA) to bring back the rocks that is set for 2033.

[...] While methane is a digestive by-product of microbes here on Earth, it can also be generated by geothermal reactions where no biology is at play.

    Not until they get back to Earth. Sample return is a game changer.
