Space activities and development have opened some new unprecedented frontiers of science and technology, and have created new hopes and goals for human society. At the same time like any other development in human history, there have been adverse effects on the environment. Of particular concern are the orbits around earth, which are polluted by space debris. Nonfunctional satellites, fragments due to satellite breakups, upper stages, etc. have created a kind of pollution that is highly dynamic. More than 26000 objects have been officially cataloged in forty years of human space activities. One third of these are still in orbit. The cataloged objects are usually larger that 10cm in diameter in LEO and 1m in diameter in higher orbits. By January 1,2000 about 8500 objects in orbit are cataloged, and approximately about 1000 objects exist which are not cataloged yet. Measurement of debris is usually done either by radar or by optical instruments. About five countries are active in radar measurement and six countries in optical measurement. United states and Russia are also actively involved in cataloging. In this paper after reviewing the current status of existing space debris, measurement, and cataloging activities, a suggestion is made for creating a global network for debris measurement, analysis, and study, for taking advantage of existing global possibilities and capabilities. This in turn will be useful in multinational activities involving space fairing and user nations.
