Status of the World Space Debris Mitigation Activities
Akira Kato
Abstract
The world concensus has been made to mitigate debris generation by the “IADC Space Debris Mitigation Guideliens” and “UNCOPUOS Space Debris Mitigation Guidelines”. But recent standards registered in NASA and European Code of Conduct for Space Debris Mitigation defind more strict requirements. These tendancy has been reflected in “ISO-24113 Space Debris Mitigation” established in 2010. JAXA is schedule to revise its
“JMR-003 Space Debris Mitigation Standard” in order to coordinate with world trand.
nd encourage international trade and launching services. . Key Words: Debris Mitigation, ISO standard, Break-up probability
