Busy at 'Lambert'
As NASA's Spirit rover stood on the summit of "Husband Hill" to acquire a 360-degree panorama, its front hazard-identification cameras took this image of an area called "Lambert." The rover also used the instruments on its robotic arm to acquire data on an undisturbed soil deposit called "Whymper." Additional data were collected on soils disturbed by the rover's wheels.
The soil is marked by wind-blown ripples and dust deposits, indicating that the summit is a very windy place. The soil composition is similar to that of deposits found in the plains, which suggests that wind has homogenized these materials over long distances.
