Chofu Aerospace Center, Japan Aerospace Exploration Agency (JAXA)(CAC)), Chofu, Tokyo, Japan, The strong increase in time of the number and mass of orbital objects imposes to have appropriate answers if one wishes to guarantee a long term sustainable operation of Earth orbits. The first step is to develop and apply general debris mitigation rules, declined in standards, codes of conduct, laws, guidelines… shared by all and clearly identified. Collision Avoidance, when possible, may prove to be efficient to avoid collision on a maneuverable satellite. The driving line of such process, known as Space Traffic Management, requires progress in Space Surveillance and Tracking means, feeding the Space Situational Awareness. As this prevention may not be enough, it may be necessary to remove the major sources of debris from orbits, in order to avoid collisions among large objects, sources of countless new debris. Numerous proposals for such Active Debris Removal have been made and often tested in orbit. Some recent works have also proposed ways to avoid collisions thanks to the slight modification of the orbit of a potentially dangerous debris. This Just-in-time Collision Avoidance process appears very promising, provided the orbital accuracy of the debris is drastically increased compared to today. The use of a small orbital laser could provide both the required orbital accuracy and the control of the position of large debris, following concepts known as Large Debris Traffic Management. The presentation will briefly describe these various steps, fundamental to guarantee our future in space., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1830034012, レポート番号: JAXA-SP-18-011}, title = {Space debris mitigation & remediation: a general update}, year = {2019} }
