Since comet 3I/ATLAS was discovered on 1 July 2025, ESA has improved its predicted location tenfold by incorporating observations from the ExoMars Trace Gas Orbiter (TGO) around Mars. TGO's in‑space measurements during the object's ~30 million‑km Mars flyby tightened trajectory uncertainty and aided global tracking.

Briefing
Tenfold reduction in trajectory uncertainty from TGO observations directly improves prediction of close‑approach geometry for Mars and Earth, enabling better timing and targeting for follow‑up observations and mission planning (see NASA's images and trajectory update: https://hype.aero/?story=6901f18a-1cb9-4168-a388-ca8191b81180).
Demonstrates the operational value of coordinated Mars‑orbiter reconnaissance during the ~30 million‑km flyby, building on earlier Mars‑orbiter mobilization and imaging campaigns that provided complementary datasets for the encounter: https://hype.aero/?story=8e9c2e9c-fe81-45e0-8800-a44a64880ee8.
Reduced orbital uncertainty strengthens the case for rapid, low‑cost reconnaissance or intercept mission concepts and refines inputs for planetary‑defense modelling and mission design: https://hype.aero/?story=35fa320d-90c6-4b9a-aa6c-d050c8103c4b.
