LATEST ADVOCACY AND ANALYSIS
October 3, 2026 — The Center for Space Environmentalism has submitted formal comments to the FCC challenging SpaceX’s application for authority to deploy and operate its 100,000-satellite Gen3 NGSO constellation. Our filing highlights SpaceX’s procedural failure to submit a mandatory Orbital Debris Assessment Report (ODAR), exposes catastrophic runaway collision hazards in crowded VLEO shells, and details unstudied upper-atmosphere alumina pollution, ground casualty risks, sub-terahertz spectrum threats to passive weather-sensing satellites, and procedural waiver abuse.

October 1, 2026 — The Center for Space Environmentalism has submitted its formal Reply Comments and Reply to Motion Opposition to the FCC regarding Amazon Leo’s 5,105-satellite Direct-to-Device constellation. Our filings expose Amazon’s self-created informational vacuum around satellite dry mass, challenge its reliance on non-binding dark sky agreements, and reject its attempt to dismiss upper-atmosphere ablation and orbital safety risks without providing counter-evidence.

September 22, 2026 — In a new statement, the Center expresses grave concern over the United States' recent confirmation that it has placed offensive weapons in orbit. We argue that this dangerous escalation threatens the long-term sustainability of the near-Earth space environment, undercuts the aims of the Outer Space Treaty, and risks triggering catastrophic debris collisions that imperil critical orbital infrastructure.

September 22, 2026 — CSE has submitted a formal response to the U.S. Federal Communications Commission regarding SpaceX's Starmind mega-constellation ex parte presentation. Our filing demonstrates that deploying 1 million four-tonne satellites will inject 800,000 metric tons of aluminum oxide nanoparticles into the upper atmosphere annually through reentry ablation, rely on flawed 15-Joule demise models disproven by real-world debris impacts, evade oversight of its optical laser mesh, and dramatically heighten Kessler Syndrome risks through untracked sub-10 cm debris collisions.
