Close Pass Successful, NEAR Shoemaker Moves Up

Before and after NEAR Shoemaker's low-altitude flyover of Eros, the camera took image mosaics of known landmarks to accurately fix the spacecraft's location. This mosaic, the last such set of "optical navigation" images inbound to the asteroid, was taken in the early hours of October 26, 2000. It is shown here in simple cylindrical map projection, centered near the equator on the 180-degree longitude end of the asteroid.

    Wrapping up a busy day that included a historic low pass over asteroid Eros, the NEAR Shoemaker spacecraft fired its thrusters one more time and headed for a higher orbit.

    At 1:40 p.m. EDT on Oct. 26, the three-minute engine burn lifted the spacecraft from a low-altitude orbit -- during which NEAR Shoemaker buzzed a mere three miles (5.3 kilometers) over one of Eros' ends -- toward a more stable position 125 miles (200 kilometers) from the center of the asteroid. The burn was the longest since NEAR Shoemaker began orbiting Eros eight months ago.

    "Had we stayed there, the low orbit could have brought the spacecraft dangerously close to the asteroid," says Dr. Robert Farquhar, NEAR mission director. "When you make a close pass like that the gravity field affects the spacecraft a lot more than it would otherwise, so we helped it along with a maneuver."

    Meanwhile, the NEAR team has just started to sift through the close-ups NEAR Shoemaker's digital camera snapped during the flyover.

    "We've never seen the surface of an asteroid or planetary satellite at this high resolution without actually landing," says Dr. Scott Murchie, NEAR imaging team member. "What strikes me most about the pictures is the diversity in the sizes and shapes of the rocks. When we analyze these high-resolution images in more detail, we'll learn something about the processes that have shaped the surface of Eros."
