The top sources for US space sustainability policy, US regulation, and current information on what is in orbit are:
- White House
- FCC
- NASA
- Space Force
- ESA
White House
The White House sets national policy.
FCC
The FCC is responsible for orbital debris mitigation and regulation according to policy and legislation.
NASA
The NASA Orbital Debris Program Office publishes a quarterly newsletter “Orbital Debris Quarterly News” (ODQN). The ODQN covers the latest events in orbital debris research, and provides orbital debris news and statistics.
Space Force
Space Force operates the US Space Surveillance Network which tracks orbital objects including space debris. They make this information available through a public website.
ESA
The ESA’s Space Debris Office coordinates ESA’s research activities in all major debris disciplines. They maintain a database of space objects. The database is called DISCOS (Database and Information System Characterising Objects in Space) and provides data for launch information, object registration details, launch vehicle descriptions, spacecraft information (e.g. size, mass, shape, mission objectives, owner), as well as orbital data histories for all trackable, unclassified objects which sum up to more than 40000 objects.
The Space Debris Office also produces an annual ESA Space Environment Report.
