A Rocky Wasteland
Laurel - May 21, 2000 - NEAR Shoemaker photographs Eros under a variety of lighting and viewing geometries suited to different science objectives. Taken with the Sun high in the sky, images with few shadows are best for mapping the color properties of the surface. Conversely, images taken from directly above a surface with oblique illumination are best for seeing landforms, because shadowing highlights the subtle shape changes on the asteroid's surface.
The whole scene is about 1.8 kilometers (1.1 miles) across, and shows features as small as 4 meters (13 feet). The rounded nature of the landforms results from formation of small impact craters over the eons. Sharp topography is eroded away by this process, and the surface is blanketed and smoothed by the fragmental debris, or "regolith." The large boulders scattered throughout the scene are the largest fragments of the rocky regolith.
