Protecting Near-Earth Space: Why We Oppose Deploying Offensive Weapons in Orbit
Protecting Near-Earth Space: Why We Oppose Deploying Offensive Weapons in Orbit
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.

CSE Exposes Severe Atmospheric and Orbital Risks in SpaceX’s 1-Million Satellite Starmind Response
CSE Exposes Severe Atmospheric and Orbital Risks in SpaceX’s 1-Million Satellite Starmind Response
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.

CSE Challenges Amazon Leo's 5,105-Satellite D2D Application and Demands Disclosure of Orbital Safety Data
CSE Challenges Amazon Leo's 5,105-Satellite D2D Application and Demands Disclosure of Orbital Safety Data
September 16, 2026 — The Center for Space Environmentalism has submitted formal comments and procedural motions to the Federal Communications Commission regarding Amazon Leo's proposed Direct-to-Device mega-constellation. Our filing highlights unaddressed upper-atmosphere pollution, optical/infrared pollution, and sweeping spectrum waivers, while formally challenging Amazon's attempt to hide vital orbital debris safety data behind FOIA trade-secret exemptions.

Will Starbase Louisiana get the backlash it deserves?
Will Starbase Louisiana get the backlash it deserves?
September 13, 2026 — Louisiana Governor Jeff Landry recently announced plans for a massive $100 billion SpaceX spaceport in the state's coastal marshes. Our latest analysis examines the extreme promises of "Starbase, Louisiana", including thousands of annual Starship flights, and questions the high-stakes economic and environmental risks for a local community heavily reliant on agriculture and fisheries.
