Uncontrolled space debris re-enters atmosphere due to atmospheric drag in low altitude. The prediction of re-entry point and time window are important for space debris issues. Orbits of re-entering objects are observed by radar and also estimated using Two-Line Elements obtained from a web site for re-entryprediction analysis. However, accurate observation by radar just before re-entry is difficult due to errors in atmospheric drag prediction. We therefore established a method called the Multi-Stage Observation to solve this problem, and made much progress in observing the objects in the last hours of re-entry in visible paths.This paper presents recent activities of space debris observation and re-entry prediction and their results obtained from three targeted satellites which re-entered in JFY 2011. In addition, means for improving prediction accuracy is further discussed.
