ATMOSPHERIC REENTRIES MONITORING
■Objects monitored:« French » objects that could fall on foreign countries (Launching State
responsibility)
-satellites and launcher stages registered by France
-launcher stages registered by ESA
« foreign » objects that could fall on the national territory:
Potentially dangerous objects registered by other countries:
-Mass > 5T
-dangerous materials
■Particular cases: IADC or governmental requests
■«debris » objects not considered

MEETINGS AND WORKSHOPS
�Meetings and workshops are regularly organized:
�To inform all partners (industry, operators, research organizations, governmental
bodies,…) on space debris activities at national and international levels
�To get their feedbacks and needs relative to mitigation rules and to research activities
�Main meetings:
�24 January 2012: GEO satellites end of Life workshop (Paris)
�18 and 19 June 2012: Active Debris Removal workshop (Paris)
�11 July 2012: annual national meeting on space debris
