The rising population of artificial satellites and associated debris in low-altitude orbits is
increasing the overall brightness of the night sky, threatening ground-based astronomy as …

In the last 40 years, the increased space activity created a new form of space environment of
hypervelocity objects—space debris—that have no functional use. The space debris …

Our radar monitoring of small Earth-orbiting debris at NASAs Goldstone Tracking Station has
been extended to an altitude of 3200 km. Many of the observed particles lie in clusters; the …

This paper proposed a new hybrid composite shielding system aimed at increasing the
specific energy absorbing rate. The hybrid composite shield is composed of an initial …

The Meteoroid Impact Detection for Exploration of Asteroids concept addresses the
challenge of characterizing an asteroid surface using a small satellite with a constellation of …

Abstract Space debris is a major threat to the satellite infrastructure. A collision with even
small particle, eg 1 cm of size, can cause a catastrophic event when the parent body …

Over 120 cases of on-orbit breakups have now been recorded. Many more undetected
events are believed to have occurred. Each time an object breaks up, whether by explosion …

1. Introduction bd~(~~~ rbiting debris is recognized as a present and growing~ d for both
humans and machines in space. Space collisions can have a closing velocity of 15 km sl …

Space debris is a major threat to the satellite infrastructure. A collision with even small
particle, eg 1 cm of size, can cause a catastrophic event when the parent body, spacecraft or …

Inferring the properties of the near-Earth meteoroid and space debris environments as
sampled by in situ detectors and retrieved spacecraft surfaces requires understanding of the …
