Around the Block
“Block Island”, the recently-discovered meteorite resting on the Martian sand dunes, is shown here in a false-color raw image by the Opportunity rover.
Measuring nearly 2 feet across, it is the largest meteorite found so far by the Mars Exploration Rovers.
Its metallic surface, pocked and pitted by erosion and its collision course through the Martian atmosphere, indicates an iron composition.
Opportunity is currently investigating its find, using its cameras and spectrometer to gather more data about this stony visitor marooned on Mars for the last few billion years.
