NASA Rover Captures Interstellar Comet Across Martian Sky
3I/ATLAS, the third interstellar comet, passed Mars at 210,000 km/h with a unique cylindrical shape, observed by multiple Mars missions, offering rare insight into interstellar objects.
- On October 4, 2025, NASA's Perseverance rover on Mars captured an image of a streak of light in the sky using its Right Navigation Camera .
- This event occurred one day after comet 3I/ATLAS made its closest recorded approach to Mars on October 3, coinciding with its passage near the planet as announced by ESA.
- Detected by the ATLAS survey on July 1, 2025, 3I/ATLAS was identified as the third known comet originating from interstellar space due to its hyperbolic trajectory and remarkable velocity.
- NASA and ESA confirmed that 3I/ATLAS 'poses no danger' to Earth as it will miss our planet by more than 1.8 AU, or about 270 million km.
- Mainstream scientists reject theories of artificial origins, attributing 3I/ATLAS's unique features such as its roughly 210,000 km/h velocity to natural interstellar processes.
