Getting into the Groove
October 27, 2009
NEAR Shoemaker's Laser Rangefinder can provide accurate topographic profiles along grooves on the surface of Eros. The spacecraft obtained this image and profile on June 2, 2000, while in a 50-kilometer (31-mile) orbit. The white line on the image shows the location of the profile, while the graph shows the differences in elevation along the line. The letters "a" through "i" indicate the location of the Laser Rangefinder spot for reference. The groove is relatively shallow except for smaller craters or possible pits within the groove (for example, at "d"). Arrows indicate approximate edges of the groove.
