(UPDATE) WASHINGTON, D.C.: 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.
