20、udy Group and the Technical Committee on the Legal Aspects of Aeronautics and Astronautics. Significant contributions were also made through the Space Operations and Support Technical Committee. The primary charge to the Study Group was to make a preliminary assessment of the existing and planned or
21、bital debris mitigation techniques in the civilian sector from an interdisciplinary perspective that would examine technical, economic, and legal/regulatory aspects. The purpose was to provide guidance to the AMA Standards Program on the mitigation techniques most promising for technical standardiza
22、tion and to recommend national and international regulatory options. The Study Group and its discipline panels held a series of meetings between May 1989 and November 1991, during which we re- ceived briefings by government representa- tives from the National Aeronautics Altoria Bell for secretarial
23、 services; and the following individuals who took the time to review this report: Jeff Anderson, Howard Baker, Walter Flury, Joel Greenberg, L a r r y Heacock, Dan Jacobs, Don Kessler, Joe Loftus Paul Maley, Barry Matsurnori, Norman Metzger, Paul Mizera, Ray Nieder, Jack OBrien, Andrew Potter, and R

26、 while also preventing the creation of more debris by protecting the spacecraft from collisions. A comprehensive strategy for ad- dressing the orbital debris problem requires consideration of both reac- tive adaptation measures and proac- tive mitigation techniques. This study focuses on the latter
27、approach, however, because the Study Group considers this to be in more urgent need of attention. The Study Group conducted a survey of in- dustry and civil government agencies and or- ganizations to obtain information on debris mitigation techniques as they relate to each debris class. For each cla
28、ss of debris, sev- eral specific mitigation techniques were pro- vided as options. Survey respondents were asked to indicate which of the listed mitigation techniques they were already using or were considering for implementation. The following is a summary of the commonly practiced techniques and t
29、hose favored by respondents for future implementation. 1 COPYRIGHT American Institute of Aeronautics and Astronautics Licensed by Information Handling Services COPYRIGHT American Institute of Aeronautics and Astronautics Licensed by Information Handling Services i AIAA SP-016-92 Some design and oper
30、ational techniques already are being used with varying degrees of acceptance: 1) Discarded rocket bodies: * Expulsion of excess propellants and pressurants * Minimization of independent launch vehicle parts allowed to reach orbit * Securing parts to the upper stages * Use of the Collision Avoidance
31、on Launch (COLA) program. 2) Spacecraft that have terminated their missions: * De-orbit and controlled reentry of low Earth orbit (LEO) spacecraft * Orbit maneuvering to shift spacecraft or components into disposal (grave- yard) orbits (not a long-term solution). 3) Operational debris released from
32、space- craft during their missions: * Lanyards attached to all potentially releasable items such as camera lens and instrument covers, equipment used by astronauts in extravehicular activities, and other material * Structural attachment of otherwise detachable elements. 4) Fragments originating from
33、 explosions or collisions * Increased shielding In addition to the above, other mea- sures appear to have widely acknowl- edged potential. Among these are: 1) Discarded rocket bodies: * Use of separation devices * Use of the Computation of Miss Between Orbits (COMBO) program * Enhancement of the acc
34、uracy of the * Selection of launch times and dates to exploit natural forces for more rapid reentry of debris into the atmosphere. 2) Spacecraft that have terminated their missions: * Retrieval and/or reuse of spacecraft * Use of active beacons for spacecraft muprogram detection and avoidance. 3) Op
35、erational debris released from space- craft during their missions: * Storing of trash and human waste, and return with logistics flights * De-orbiting trash and human waste for incineration in the atmosphere. 4) Fragments originating from explosions or collisions * Protecting and preventing hardware
36、 * Designing for graceful degradation of * Incorporating adequate shielding * Use of low fragmentation materials. No formally adopted technical design or operations standards, guides, or even recommended practices currently exist for the mitigation of orbital debris. Nevertheless, the survey conduct
37、ed through this study and supplemented by a review of the literature shows there are already a number of voluntarily adopted and widely practiced techniques. Although certain techniques are more commonly practiced than others, there is an increased awareness of the need to use them and a trend towar
38、d their continuation, both within the public and private sectors. The very existence of these voluntarily adopt- ed design and operational techniques for reducing the amount of artificial debris in Earth orbit leads to several conclusions. One is that both the government and the private sectors reco
39、gnize that debris poses a potential hazard to operations in Earths orbital envi- ronment. This is not a new finding in the context of government policies. Several re- cent government reports have focused on the problem and have strongly supported imple- mentation of debris mitigation techniques. The
40、 finding is significant, however, in terms of private sector actions, because any design or operational practices in that sector have been developed voluntarily, rather than in re- sponse to any government regulations or agreements, indicating some level of corpo- rate self interest.

42、dling Services manufacturers or operators and that have been shown to be effective indicate the most promising areas to be pursued in the near future. This is especially the case for mitigation techniques practiced by the space agencies or companies of more than one na- tion. That a certain mitigati
43、on technique has been successfully used in the operational and commercial space environment provides a presumption in favor of its technical feasibility and cost effectiveness. This, in turn, makes such a technique a logical candi- date for closer investigation as a potential in- dustry or regulator
44、y standard. Nevertheless, no particular debris mitigation technique currently practiced by any portion of the industry provides a sufficiently com- pelling rationale for that technique to become an industry-wide standard without further in- vestigation and analysis. A number of tech- nical and econo
45、mic tradeoffs still need to be considered. The Study Group has identi3ed four categories of debris mitigation measures that are the most promising candidates for near-term standardiza- tion, based on a preliminary technical assessment of the survey results and the current knowledge of the debris env
46、ironment. These categories of techniques have been selected be- cause of their demonstrated accep- tance among a number of spacecraft manufacturers and operators, and because of their potential effectiveness in reducing the debris hazard. 1 ) Venting of residual fuel and pres- surants from discarded
47、 rocket bodies. Debris from exploded rocket bodies (34 breakup events recorded as of 1991) accounts for over 1900 of the cataloged objects in Earth orbit. The venting of residual fuel and pressurants is a relatively simple and inexpensive technique already used in many U.S., European, Russian, and J
48、apanese launches, but it has not been adopted by all launching government agencies or companies. 2) Boosting of satellites from AlAA SP-016-92 geosynchronous Earth orbit (GEO) into disposal orbits. The satellite popula- tion in geosynchronous orbit is growing rapidly. The GE0 is unique for com- muni
49、cations purposes and for synoptic re- mote sensing observations, m a k i n g it an im- portant strategic and economic location. More GE0 satellites have been deployed over the past decade than in all previous years combined, and the launch rate is expected to increase. There is no natural cleansing mech- anism, such as atmospheric drag, so that any hardware deposited in GE0 may remain in- definitely. A large number of GE0 satellite operators in the U.S. and in other countries already use a variety of boosting techniques, some more effectively than others, near the end of useful lif
