Institutionally tracked Editorial judgment

The previous UCS Satellite Database citation remains unusable (still paused since May 2023, re-checked live). UNOOSA's treaty-mandated UN Register of Objects Launched into Outer Space (~85% of all launched spacecraft entered) sources Satellite launch services (#2) and National space programs (#5) by launching state. ITU's Space Services Department / Master International Frequency Register sources Satellite communications (#1) and, via GPS.gov's official constellation status reporting, GPS & navigation systems (#3). ESA's Earth observation program pages source Earth observation (#4); ESA's Space Debris Office Annual Space Environment Report sources Space debris management (#11). The FAA Office of Commercial Space Transportation, which licenses commercial launch/reentry and suborbital human spaceflight, sources Commercial spaceflight (#6) and Space tourism (#13). NASA's mission-tracking pages source Space exploration (#7), Human spaceflight & space stations (#10, ISS operations), and Lunar exploration & lunar economy (#15, Artemis — covers exploration, not lunar-economy valuation specifically). NASA JPL's Center for Near-Earth Object Studies sources Deep-space & asteroid resource exploration (#14). NASA's CubeSat Launch Initiative sources Small satellite/cubesat industry (#17) — tracks NASA-sponsored educational CubeSat launches specifically, not the full commercial smallsat industry. The Satellite Industry Association's State of the Satellite Industry Report sources Satellite manufacturing (#8) and Ground equipment & infrastructure (#9). The Secure World Foundation's Global Counterspace Capabilities Report sources Military space systems (#12). Space-Track.org, the US Space Force's public orbital- object catalog, sources Space situational awareness (#20). Launch vehicle manufacturing, Space insurance, and In-space manufacturing & servicing have no verified institutional tracker and stay editorial.
