Curiosity used its robot arm to touch at a football-sized pyramid-shaped?rock?for the first time two weeks ago. It also shot the?rock?dozens of times with a laser.

The results surprised scientists. They said Thursday that it is not like other?rocks?seen on?Mars. It has more sodium and potassium.

Scientist Edward Stolper said the?rock?is more like rare volcanic?rocks?seen on Earth in places like Hawaii. Those?rocks?are formed under high pressure, deep underground and once contained water.

Scientists don't know how old the Martian?rock?is.
