Processes of Science: Mars, a Case Study #6015 Iron Meteorite


Date: January 6, 2005
Location: Mars
Photographer: NASA’s Mars Exploration Rover Opportunity
Source: NASA/JPL/Cornell


NASA’s Mars Exploration Rover Opportunity found an iron meteorite on Mars: the first meteorite of any type ever identified on another planet. The pitted, basketball-size object is mostly made of iron and nickel. Readings from spectrometers on the rover determined its composition. Opportunity used its Panoramic Camera to take the images used in this approximately true-color composite on the rover’s 339th Martian day, or sol (Jan. 6, 2005). This composite combines images taken through the panoramic camera’s 600-nanometer (red), 530-nanometer (green), and 480-nanometer (blue) filters.
