What does a Martian crater look like?

NASA unveils new pictures from Mars


National Aeronautics and Space Administration (NASA) released images taken by Exploration Rover ‘Opportunity’ in the west rim of Endeavour crater, located on the planet’s region of Meridiani Planum.


Endeavour crater has a diameter of 22 kilometres. It is over 25 times wider than any that ‘Opportunity’ has previously approached during the rover’s 90 months on Mars.



The lighter-toned rocks closer to the rover in this view are similar to the rocks Opportunity has driven over for most of the mission. However, the darker-toned and rougher rocks just beyond that might be a different type for Opportunity to investigate. The ground in the foreground is covered with iron-rich spherules, nicknamed “blueberries,” which ‘Opportunity’ has observed frequently since the first days after landing. They are about 5 millimetres or more in diameter[1].

Mars rover ‘Spirit’ and ‘Opportunity’ were launched by NASA in the summer of 2003.
