Orbital Debris Quarterly News

The Orbital Debris Quarterly News (ODQN) is a quarterly publication of the NASA Orbital Debris Program Office. The ODQN publishes some of the latest events in orbital debris research, offers debris news and statistics, and presents project reviews and meeting reports, as well as upcoming events. Each issue is available as a downloadable PDF file.


For Space Actors

UN Space debris mitigation guidelines

A full PDF of the United Nations Space Debris Mitigation Guidelines of the Committee on the Peaceful Uses of Outer Space. Officially signed in December 2007, the voluntary guidelines are derived from a collection of IADC recommendations and current orbital debris mitigation processes being carried out by other states.

Compendium on Space Debris Mitigation Standards

For the UN Committee on the Peaceful Uses of Outer Space, representatives from Canada, the Czech Republic, and Germany collaborated to produce this report outlining member states’ space debris mitigation efforts and legal mechanisms. This is a living document that currently does not include profiles on Russia or China.

NASA Orbital debris program office

NASA’s Orbital Debris Program Office, headquartered at the Johnson Space Center in Texas, conducts measurement, modeling, and mitigation recommendations regarding orbital debris.

inter-agency space debris coordination committee (iadc)

IADC is an international governmental forum for the worldwide coordination of activities related to the issues of man-made and natural debris in space. The primary purposes of the IADC are to exchange information on space debris research activities between member space agencies, to facilitate opportunities for cooperation in space debris research, to review the progress of ongoing cooperative activities, and to identify debris mitigation options.

Nasa’s Process for limiting orbital debris (2012)

Download-able document to NASA’s Procedural Requirements 8715.6 providing specific requirements and methods to comply with requirements for mitigating orbital debris.


For the Curious

United Nations Register of Space Objects

The UN Space Object Registrar is a means through which space actors can monitor what space assets belong to which space actors. More than 90 percent of all satellites, probes, landers, crewed spacecraft and space station flight hardware launched into space are registered here.

CORDS Reentry database

Learn more about orbital debris re-entries from the Center for Orbital and Reentry Debris Studies (CORDS). It catalogs what landed where, and when.
