NASA Sets Nov. 19 Briefing to Unveil Multi‑Mission Images of Interstellar Comet 3I/ATLAS

Coordinated measurements refined the orbit, confirming a distant, no‑threat pass.

Overview

  • NASA will stream the Goddard-based briefing at 3 p.m. EST on Nov. 19 across NASA+, the agency website and app, YouTube, and Amazon Prime.
  • Amit Kshatriya, Nicky Fox, Shawn Domagal‑Goldman, and Tom Statler will lead the update on results from spacecraft and telescope observations.
  • Refined solutions show a closest Earth approach on Dec. 19 at roughly 270–273 million kilometers, after an early‑October pass about 30 million kilometers from Mars, with a hyperbolic departure and a Jupiter flyby in March 2026.
  • ESA’s ExoMars Trace Gas Orbiter data combined with NASA JPL/HORIZONS inputs improved position predictions by about an order of magnitude, enabling sharper trajectory forecasts.
  • Discovered July 1 by the ATLAS survey as the third confirmed interstellar visitor, 3I/ATLAS is being studied for activity and composition; agencies reject claims of artificial origin as scientists report early, still‑developing findings such as elevated CO₂ and nickel.
