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. Received on Mon 29 Jan 2001 12:42:05 PM PST |
