NASA’s Hubble Captures Interstellar Comet 3I/ATLAS Ahead of Close Mars Flyby

On October 3, 2025, interstellar comet 3I/ATLAS will pass just 30 million km from Mars — nine times closer than from Earth. ESA’s Mars Express and TGO, along with NASA and China’s orbiters, will attempt to image its coma, analyze gases, and study this rare visitor from beyond the solar system.
