MAJIS data were used to estimate that 3I/ATLAS was losing about two tons of material per second from its nucleus.
JUICE’s mission team planned a dedicated observation campaign for 3I/ATLAS during the spacecraft’s interplanetary cruise to Jupiter.
JANUS images showed 3I/ATLAS with an extended coma, a tail, and morphological structures including rays, jet-like features, and filaments.
The JANUS multiband camera on JUICE observed 3I/ATLAS in five observing windows between 5 November 2025 and 25 November 2025.
JANUS collected more than 120 images of 3I/ATLAS using seven filters.
Leo Atlas 5 (LA-05) was the first of four back-to-back Atlas missions with United Launch Alliance.
MAJIS detected infrared emissions from water vapor and carbon dioxide in 3I/ATLAS on 2 November 2025, four days after the comet’s perihelion on 29 October 2025.
ESA’s JUICE mission observed the interstellar comet 3I/ATLAS in November 2025 while traveling to Jupiter and its icy moons.
The JUICE observations of 3I/ATLAS provided an operational demonstration relevant to future studies of Jupiter’s icy moons and Jupiter’s rings.
The estimated outgassing from 3I/ATLAS was approximately equivalent to 70 Olympic swimming pools of water vapor per day.
Weaker emissions from 3I/ATLAS were observed by MAJIS on 12 November 2025 and 19 November 2025.
JUICE was in a favorable position relative to 3I/ATLAS when Earth-based observations of the comet were no longer possible.
MAJIS also observed light scattering through 3I/ATLAS’s coma in visible and near-infrared light.
Ground-based observations of 3I/ATLAS ended in early October 2025 as the comet’s apparent distance from the Sun decreased and its brightness increased unexpectedly.
The Three Man Space System Experimental Laboratory was planned to be launched by Atlas Centaur.
PeakSat and ERMIS-3 flew Atlas-1 terminals from Astrolight.
