NASA's ISS Deorbit Plan Draws Legal, Environmental Scrutiny Ahead of 2030 Ocean Reentry
3 articles · Updated · Space.com · Jun 23
Summary
A GAO report and the Ocean Foundation have intensified scrutiny of NASA’s plan to send the International Space Station into the Pacific at Point Nemo in late 2030 or early 2031.
NASA’s blueprint calls for the ISS to begin descending in 2028, then for a SpaceX-built U.S. Deorbit Vehicle launched in 2029 to use 46 Draco thrusters to drive the final reentry.
The Ocean Foundation says the football-field-sized station could leave dense debris on the seafloor and create atmospheric effects that have not been adequately studied or publicly disclosed.
Mark Spalding argues international law protects nations from falling space debris under the 1972 Space Liability Convention but leaves no equivalent cleanup or compensation obligation for damage on the high seas.
The group is urging a full environmental impact assessment and legal review under UNCLOS, the 1996 London Protocol and the High Seas Treaty, potentially widening oversight of future spacecraft disposal.

Overview
NASA is preparing to safely deorbit the International Space Station (ISS) around 2030-2031 due to its aging structure and increasing technical limitations. The agency has awarded SpaceX a major contract to build a specialized deorbit vehicle, highlighting the complexity of this unprecedented task. As the ISS nears retirement, NASA and its partners are planning a transition to multiple smaller, commercial space stations to maintain a human presence in low Earth orbit. However, this shift raises concerns about potential gaps in U.S. leadership, environmental impacts on oceans and the atmosphere, and the lack of clear international legal frameworks to manage the consequences of large-scale space debris.
