Public Update – 3I/ATLAS Observation & Contingency Scenario
Dean Bordode, Citizen / Concerned Observer
Recent observations of interstellar object 3I/ATLAS highlight a very low-probability—but potentially high-consequence—scenario: the presence of an advanced interstellar probe or artificial object. Even at an estimated probability of ≈0.1 %, the potential consequences for humanity are existential.
Observation Efforts
I have submitted requests for thermal-IR, polarimetric, γ-ray, and radio observations of 3I/ATLAS to relevant agencies. The goal is to detect any intrinsic emission >10²⁴ erg s⁻¹ or anomalous Δv > 0.1 km/s, which could indicate artificial activity.
While current evidence suggests 3I/ATLAS is likely a natural comet, rational precaution requires monitoring for any anomalies, including unusual light emission, trajectory deviations, or behavior near the Sun.
Policy & Precaution
I have also formally requested that all terrestrial kinetic conflicts, live-fire exercises, and nuclear tests be temporarily suspended. This preserves propellant, munitions, and political bandwidth for potential exo-atmospheric and orbital defense, should anomalous activity be confirmed.
Key Facts
Trajectory Highlights:
Near Mars: 0.19 AU (Oct 3, 2025)
Perihelion: 1.36 AU, just inside Mars’ orbit (Oct 29, 2025)
Near Earth: 1.80 AU (Dec 19, 2025)
Near Jupiter: 0.36 AU (Mar 16, 2026)
Orbit: Nearly retrograde, inclined ~5° to the ecliptic.
Observation Window: The critical monitoring period remains 21 Nov–5 Dec 2025, during which any Δv ≥ 0.5 km/s or IR flare ≥ 10²⁴ erg s⁻¹ would trigger a reassessment.
Scenario Summary
First interstellar objects may act as scouts, mapping biosignatures and testing planetary defenses.
Observed anomalies, such as brightness changes or Sun-hiding maneuvers, are currently explainable by natural phenomena, but remain under study.
Precautionary monitoring ensures humanity is prepared if unusual activity is confirmed.
Bottom Line
Probability of a hostile or artificial object is extremely low, but the consequence is existential.
Scientific observation, transparency, and precautionary defense planning are essential.
Public and scientific awareness helps ensure rational, evidence-based decision-making.
