Bounce Rock is a football-sized primarily pyroxene rock found within the Meridiani Planum of the planet Mars. It was discovered and observed by the Mars Exploration Rover Opportunity in April 2004. The rock was named for it having been struck by Opportunity as the craft bounced to a stop during its landing stage.
