NASA: Curiosity rover makes big discovery

NASA will announce its historic news about a discovery on Mars in a little more than a week in San Francisco.

Scientists say the Curiosity rover found something interesting in the soil. They would not say what it is, but they say it'll be one for the history books.

Right now they're double-checking their data to make sure it's correct.

Curiosity landed on Mars August 5. It'll spend two years collecting and analyzing samples in a search for life on the Red Planet.
