The Subcommittee also noted that, in fact, many space missions were debris free and when the release of mission related debris was unavoidable, the number of debris and their orbital lifetimes were minimized to the extent possible.

The Subcommittee agreed to focus on understanding aspects of research related to space debris, including debris measurement techniques mathematical modelling of the debris environment characterizing the space debris environment and measures to mitigate the risks of space debris, including spacecraft design measures to protect against space debris.

11. The task of litter free operations could combine design and operational practices to achieve the goal of limiting further orbital debris created by any space operations.

Space debris flux and meteoroid influx are essential for validation of space debris environmental models.

Measures for the reduction of space debris growth include methods for debris prevention and removal.

1. Measurements of space debris

Amongst the topics discussed were short term and long term debris hazard modelling, ground based optical and radar detection of debris objects, measurement of the micro debris through the analysis of retrieved surfaces, and international initiatives relating to space debris.

Debris environment models

Critical analysis of the relative importance of the role played by space debris on elliptical orbits (especially with regard to debris with small dimensions and at low altitudes) in overall debris pollution

Because of the smaller population of large debris objects, the likelihood of collision decreases rapidly as the size of the debris increases.

(b) Space debris, as agreed by the Working Group on Space Debris (para.  of annex to the present report).

The most critical uncertainties in space debris problems are due to our ignorance of the exact space debris environment.
