Focus on 'Rue Legendre'

Sept. 1, 2005
On Aug. 3, 2005, NASA's Mars Exploration Rover Spirit used its microscopic imager to take this mosaic of the rock 'Haussmann.' The rounded nature of the pebbles indicates that they were eroded on the surface before being embedded into the rock.

Spirit used its microscopic imager to take this mosaic of the rock "Haussmann" on martian day, or sol, 563 (August 3, 2005). The specific target is nicknamed "Rue Legendre." The rounded nature of the pebbles indicates that they were eroded on the surface before being embedded into the Haussmann rock. The size of the larger of the two pebbles is approximately 3 centimeters (1.2 inches). The rock probably formed from impact ejecta, consistent with other rocks Spirit discovered during its climb to the summit of "Husband Hill."
