17、 AstronauticsLicensed by Information Handling ServicesAIAA SP-OLb 92 m Ob95534 0000923 983 m AIAA SP-016-1992 Foreword This study was initiated in May 1989 under the combined ausrices of the AIAA Stan- dards Program Orbital Debris Study Group and the Technical Committee on the Legal Aspects of Aeron

18、autics 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 orbital debris mitigation techniques in the civilian sector from an i

19、nterdisciplinary 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 standardization and to recommend national and international regulatory options

20、. 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 services; and the following individuals who took the time to revie

A comprehensive strategy for ad- dressing the orbital debris problem requires c

24、onsideration of both reac- tive adaptation measures and proac- tive mitigation techniques. This study focuses on the latter 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

25、 and or- ganizations to obtain information on debris mitigation techniques as they relate to each debris class. For each class 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

26、 already using or were considering for implementation. The following is a summary of the commonly practiced techniques and those favored by respondents for future implementation. 1 COPYRIGHT American Institute of Aeronautics and AstronauticsLicensed by Information Handling Servicesi AIAA SP-016-92 S

28、ollision Avoidance 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 de

Among these are: 1) Discarded rocket bodies: * Use of separation devices * Use of the Computation of Miss Between Orbits (COMBO) program * Enh

33、preventing hardware * 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,

34、 the survey conducted 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 the

35、m and a trend toward 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 p

36、rivate sectors recognize 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 mitigat

37、ion techniques. The 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 intere

38、st. Debris mitigation practices that have been adopted separately by two or more elements from exploding components and systems COPYRIGHT American Institute of Aeronautics and AstronauticsLicensed by Information Handling Servicesmanufacturers or operators and that have been shown to be effective ind

39、icate 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 mitigation technique has been successfully used in the operational and commercial space enviro

40、nment 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 regulatory standard. Nevertheless, no particular debris mitigation technique currently practice

41、d 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 economic tradeoffs still need to be considered. The Study Group has identi3ed four categori

42、es 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 environment. These categories of techniques have been selected be- cause of their demonst

43、rated 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 rocket bodies. Debris from exploded rocket bodies (34 breakup events recorded as of 1

44、991) 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 Japanese launches, but it has not been adopted by all launching government agencies or

45、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- munications purposes and for synoptic re- mote sensing observations, making it an im- port

46、ant 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-

47、 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 life of their spacecraft. These techniques need to be evaluated fully from technical and economic standpoi

48、nts so that a common approach with a minimum set of effective performance standards can be instituted. 3) De-orbiting spent hardware. The majority of all orbital debris consists of rocket bodies and payloads abandoned after their use. If left in space, this class of debris may provide a significant

49、portion of the source material for a self-perpetuating se- quence of collisions in the future. De-orbit- ing objects like these could significantly reduce the risk of collisions and the creation of hazardous fragmentation. 4) Reducing operational debris. Operational debris accounts for approxi- mately 12 percent of all cataloged objects in Earth orbit. Operators of expendable launch vehicles, satellite, and piloted vehicles al- ready have taken some corrective actions to reduce this type of debris. Their practices should be examined to determine the design penalties and cost tradeoff
