Our radar monitoring of small Earth-orbiting debris at NASA's Goldston
e Tracking Station has been extended to an altitude of 3200 km. Many o
f the observed particles lie in clusters; the largest of which appears
to be remnants of the West Ford Needles, launched over 3 decades earl
ier, and originally designed to have reentered the Earth's atmosphere
long ago. (C) 1998 Elsevier Science Ltd. All rights reserved.
