What Is The Historic Discovery On Mars?
That’s the word that NPR reporter Joe Palca used yesterday to describe a discovery by the new Mars rover, Curiosity. He quoted a NASA scientist as describing the discovery as “one for the history books”.
The thing is, NASA won’t tell what it’s discovered, yet. They have to double-check the data first.
They have given the clue that the discovery came through a chemical analysis of a Martian soil sample.
