Triangulation of data from ExoMars TGO with Earth-based observations improved the predicted path of 3I/ATLAS by ten-fold.
The astrometric measurements of comet 3I/ATLAS from ExoMars TGO are the first accepted into the Minor Planet Center database from a spacecraft orbiting another planet.
Between 1 and 7 October, ESA's ExoMars TGO observed interstellar comet 3I/ATLAS from its orbit around Mars.
3I/ATLAS approached Mars to about 29 million km during its closest phase on 3 October.
The improved trajectory from Mars data allows astronomers to aim their instruments with confidence for studying 3I/ATLAS.
The Mars probe ExoMars TGO got about ten times closer to 3I/ATLAS than Earth-based telescopes.
The CaSSIS instrument on ExoMars TGO was used to aim at the skies above Mars to observe 3I/ATLAS.
The 6-ton Viasat 3 satellite will be deployed from the Atlas rocket about 3 1/2 hours after launch.
The Atlas 5 launch mission was scrubbed repeatedly due to a faulty liquid oxygen tank vent valve on the Atlas booster rocket.
Numerical integrations indicate that C/2025 K1 (Atlas) originates from the Oort Cloud at the outskirts of the solar system.
The Atlas and Centaur stages have been powered to begin launch day testing.
C/2025 K1 (Atlas) is likely making its first passage through the inner solar system.
A variety of images of the fragmented nucleus of C/2025 K1 (Atlas) were obtained in the r-Sloan filter.
C/2025 K1 (Atlas) is classified as an 'hyperbolic' comet, indicating it is on an open orbit.
Due to its proximity to the Sun, C/2025 K1 (Atlas) experienced high solar irradiation, resulting in a significant increase in temperature of its surface and internal layers.
Comet C/2025 K1 (Atlas) was discovered in May 2025 through the Atlas (Asteroid Terrestrial-Impact Last Alert System) program.
The Atlas program, funded by NASA, utilizes four telescopes located in Hawaii, Chile, and South Africa to search the sky for potentially dangerous asteroid objects each night.
The orbit of 3I/ATLAS brings it into the inner solar system with a high inclination relative to the ecliptic.
The continuing approach of 3I/ATLAS and its predicted exit from the solar system in 2026 provide unique opportunities for collecting data.
3I/ATLAS is estimated to be around 800 meters in diameter and has a hyperbolic trajectory that confirms its interstellar origin.
