CURIOSITY set to reveal 'major discovery' in Martian soil

Nasa's Mars Curiosity rover has reportedly made a major discovery on the Red Planet - but scientists are keeping quiet about what it is.

The finding was made by the six-wheeled rover's Sample Analysis at Mars (SAM) instrument in the Rocknest area of the Gale Crate, close to where the rover touched down.
SAM is Curiosity's on-board chemistry lab and is able to take a sample of Martian rock, soil or air and find out what it is made of. Most importantly, it is capable of identifying organic compounds - carbon containing substances that could indicate life.

Except scientists are refusing to reveal its latest finding, merely saying that it is earthshaking. 'This data is gonna be one for the history books.
