¶Megaconstellations proliferate. On the day of the FCC’s deadline for satellite V-band applications, four companies filed independent requests to build megaconstellations: Astra (13,620 sats), Hughes Net (1,440 sats), Inmarsat (198), and Telesat (increasing current constellation to 1,671). The FCC also approved a 2017 request from Boeing to build a 147 sat mixed LEO and non-GEO high-orbit (between 27,355 and 44,221 km) broadband internet constellation. All these constellations would join Starlink (currently at 1,584 satellites, with the next phase planned for 4,400, and future phases growing it to as many as 42,000) and OneWeb (358 deployed, 648 planned), along with the planned Project Kuiper (3,236 sats, and up to 15,000 in the future). Other constellations are being proposed outside the US: China’s SatNet (13,000 satellites rumored), Chinese GalaxySpace’s Yinhe (1,000), Polish SatRevolution’s STORK/REC (1,024), Korean Hanwha Systems (~2,000), Russia’s Sfera constellation (>600), and …many others? While some of these projects will never achieve operational status, the reality of multiple tens of thousands of satellites is looking inevitable. We crossed 1,000 operational satellites in 2013, doubled that number by 2018, and are now well past 4,000. The shared commons of Earth’s orbital space is quickly getting crowded.
