This is an image of the meteorite that NASA's Mars Exploration Rover Opportunity found and examined in September 2010.

Opportunity's cameras first revealed the meteorite in images taken on Sol 2363 (16 September 2010), the 2,363rd Martian day of the rover's mission on Mars. This view was taken with the panoramic camera on Sol 2371 (24 September 2010).

The science team used two tools on Opportunity's arm – the microscopic imager and the alpha particle X-ray spectrometer – to inspect the rock's texture and composition. Information from the spectrometer confirmed that the rock is a nickel-iron meteorite. The team informally named the rock "Oileán Ruaidh" (pronounced ILL-lawn ROO-ah), which is the Irish language name for an island off the coast of County Donegal in Ireland.

Opportunity departed Oileán Ruaidh and resumed its journey toward the mission's long-term destination, Endeavour Crater, on Sol 2374 (28 September 2010) with a drive of about 100 metres (328 feet).

The component images were taken through three Pancam filters admitting wavelengths of 753 nanometres, 535 nanometres and 432 nanometres. This view is presented in false colour to make some differences between materials easier to see.
