NASA Mars Rover Curiosity: Traces of Past Life Discovered?

As space fans anticipate news of organic molecules from the Mars Curiosity rover – cryptically teased by the mission's chief scientist, John Grotzinger, there's one man who is even more excited than most.

Former NASA researcher Gilbert Levin says that a positive sign of organics by Curiosity would confirm his claim that NASA has already seen evidence for life on Mars – from an experiment called Labeled Release that went to the Red Planet aboard the Viking mission.

If Curiosity has found evidence for organics, as many are hoping, "that removes the last barrier to my interpretation of the Labeled Release results, and leaves us free and clear", Levin reported.

Though the prospect of new Curiosity findings have set the internet abuzz, nobody from NASA has yet said publicly what they are: Grotzinger has refused to elaborate journalists, to a presentation scheduled for the American Geophysical Union annual meeting in San Francisco, which begins on 3 December.
