# The FCC's five-year deorbit mandate and the atmospheric chemistry problem from satellite reentry are in direct governance tension: optimizing orbital debris mitigation by mandating rapid reentry accelerates atmospheric aluminum deposition, and no regulatory framework considers both simultaneously

The FCC's 5-year deorbit rule — the primary orbital debris mitigation tool — mandates rapid satellite reentry to reduce collision risk. A satellite forced to reenter in 5 years instead of remaining in a graveyard orbit at 600km deposits its aluminum directly into the lower atmosphere, where it persists for 30+ years as an ozone-depleting catalyst.

This creates a governance paradox: optimizing for one problem (orbital debris) makes the other worse (atmospheric chemistry). SpaceX's January 2026 decision to lower 4,400 Starlink satellites to faster-deorbit orbits for orbital safety illustrates this tension in practice — the orbital safety measure accelerates atmospheric aluminum deposition.

Researchers proposed in January 2026 that satellites designed for extremely long operational lifetimes in higher graveyard orbits might actually be preferable to rapid-deorbit satellites, despite worse orbital debris optics. This inverts the current governance assumption that rapid deorbit is always better.

No regulatory framework addresses both problems simultaneously. The FCC governs orbital debris through the 5-year rule. The Montreal Protocol governs ozone-depleting substances but was designed for CFCs and halons, not aluminum oxide from satellite reentry. The FAA received the Ferreira paper as a formal comment in rulemaking FAA-2024-1395 but has taken no action. Two separate regulatory frameworks (orbital debris, atmospheric chemistry) are in direct tension, and no authority has jurisdiction over both.
