Bounce Rock
Bounce Rock is a football-sized primarily pyroxene rock found within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. It was discovered and observed by the Mars Exploration Rover ''Opportunity'' in April 2004. The rock was named for the fact that it was struck by ''Opportunity'' as the craft bounced to a stop during its landing stage. Bounce Rock bears a striking resemblance〔Squyres et al., 2006, Journal of Geophysical Research, vol.111, E12S12, doi:10.1029/2006JE002771, “Overview of the Opportunity Mars Exploration Rover Mission to Meridiani Planum - Eagle Crater to Purgatory Ripple”.〕 to a class of meteorites found on Earth known as shergottites, that are believed to have originated from Mars. ==See also==
