Mars Rover Sees Hints Of Past Life In Latest Rock Samples
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.
[...] 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.
[...] The results showed a class of organic molecules called aromatics, which play a key role in biochemistry.
"This is a treasure hunt for potential signs of life on another planet," NASA astrobiologist Sunanda Sharma said.
"Organic matter is a clue and we're getting stronger and stronger clues...I personally find these results so moving because it feels like we're in the right place, with the right tools, at a very pivotal moment."
