The Impact of Deorbiting Space Debris on Stratospheric Ozone

Abstract
The Environmental Management of the Space and Missile Systems Command has set out to evaluate the depletion of stratospheric ozone caused by Air Force activities in space. Potential destruction of ozone by launch vehicle exhaust is one item of concern (Ref. 1.1). The use of advanced propellants to minimize launch-induced ozone destruction is discussed in a companion report. The present report describes a quantitative assessment of another potential destroyer of stratospheric ozone: deorbiting space debris. The results of the present study lead to the conclusion that deorbiting space debris has very little impact on stratospheric ozone.
