![]() NEAR Shoemaker took this picture at 8:45 p.m. EST on January 25, 2001, during one of the spacecraft's low-altitude passes over the surface of Eros. The distance to the center of the picture is only 9 kilometers (5.6 miles), so the entire scene is a mere 340 meters (1,120 feet) across. At this scale, we can distinguish features less than 2 meters across. The asteroid's surface appears nearly devoid of obvious craters and is instead dominated by small boulders. In the upper left part of the image, a smooth deposit with a lower density of boulders is in contrast to the very rough-textured material seen at the lower right. |
The daring pass-the closest any spacecraft has come to an asteroid-marked the conclusion of a 4-day series of low-altitude flyovers that is returning extraordinarily detailed images of the asteroid's surface.
The low pass sequence ended this afternoon at 1:22 p.m. EST (ground receive time), when a 3.8-second burst from the spacecraft's 5-pound thrusters pulled it away from its breathtaking vantage point, and back toward an orbit 22 miles (35 kilometers) above the asteroid.
There it will remain circling Eros until a maneuver on Feb. 12 pulls the spacecraft out of orbit and into position for its descent to the asteroid. Several more engine burns will slow NEAR Shoemaker's descent, allowing it to settle on to the asteroid's surface at about 3 p.m. EST.
