Between Oct. 1 and 7, ESA’s ExoMars Trace Gas Orbiter and Mars Express turned their instruments toward interstellar comet 3I/ATLAS as it zipped past Mars. The orbiters collected complementary remote‑sensing data during the comet’s roughly 30 million‑kilometre close approach, adding in‑space vantage points to telescope observations.

Briefing
ESA's in‑space observations add a unique Mars‑proximate viewpoint as 3I/ATLAS passed roughly 30 million km from Mars, improving constraints on trajectory and activity: https://hype.aero/?story=8e9c2e9c-fe81-45e0-8800-a44a64880ee8
The data complements JWST, Hubble and other telescope detections and informs technical assessments of rapid smallsat or flyby concepts for interstellar objects: https://hype.aero/?story=20dbf044-005b-43df-9a9e-ce1c5225491f and https://hype.aero/?story=35fa320d-90c6-4b9a-aa6c-d050c8103c4b
