THE REFINED FUEL: They Clocked the Exhaust of 3I/ATLAS at Closest Approach. Half Speed. Wrong Direction. And the Sulfur Is Gone.
The Sentinel argues the findings are more consistent with propulsion than a comet model.

A team led by Nicolas Biver at the Paris Observatory measured the gas coming off 3I/ATLAS at 0.37 kilometers per second.
On November 1 through 3, 2025, three days after closest approach to the Sun, a team led by Nicolas Biver at the Paris Observatory pointed Europe’s largest millimeter telescope at 3I/ATLAS and measured the gas coming off the object at peak output.

The Sentinel reports that the observed gas-velocity structure is asymmetric and interprets it as stronger sunward-directed outflow.
The gas moves faster toward the Sun than away from it.

The Sentinel Dossier identified the sunward jet as a retro-rocket.

The source reports elevated carbon- and oxygen-bearing compounds, while sulfur species were not detected in the IRAM survey.
The carbon and oxygen compounds are elevated. Sulfur is gone.
- Source reportedAsserted
The source says the measured water production would require an effective sublimating area much larger than the object’s physical surface if surface ice alone were responsible.
To produce that much water from the surface alone, the nucleus would need to be nine times its own size in pure exposed ice.

Shinnaka's group found carbon dioxide still elevated above typical comets on the outbound leg.
Carbon dioxide was still elevated above typical comets, comparable to the previous interstellar visitor, 2I/Borisov.

The drive of 3I/ATLAS was on when the object was far from the Sun and heading in, and it is still on now.
The drive was on when the object was far from the Sun and heading in. It is still on now, far from the Sun and heading out.
