ULA technicians transported the Amazon Leo Atlas 4 (LA-4) payload to the Vertical Integration Facility.
Thomas Puzia is an astrophysicist who led the team that discovered Comet 3I/ATLAS.
MAVEN (Mars Atmosphere and Volatile EvolutioN) orbiter captured unique ultraviolet images of 3I/ATLAS that help determine its chemical makeup and water vapor release.
Avi Loeb, a Harvard Professor, has accused his peers of lacking open-mindedness regarding the possibilities of Comet 3I/ATLAS.
NASA's Mars Reconnaissance Orbiter (MRO) observed interstellar comet 3I/ATLAS from 19 million miles (30 million kilometers) away on October 2.
Astronomers have had months to observe Comet 3I/ATLAS, unlike previous interstellar objects.
MRO's imagery, captured at a scale of roughly 19 miles (30 kilometers) per pixel, shows 3I/ATLAS resembling a pixelated white ball.
NASA's Perseverance rover employed long exposure techniques to capture 3I/ATLAS, which resulted in star trails appearing as streaks in its images.
Amit Kshatriya is a senior NASA official who emphasized that 3I/ATLAS is a comet, not a spacecraft.
At the time of imaging by Perseverance, 3I/ATLAS was located about 19 million miles (30 million kilometers) from the rover, which was exploring Jezero Crater.
IUVS then snapped high-resolution UV images to identify hydrogen emissions from 3I/ATLAS.
Over 10 days starting on September 27, MAVEN captured 3I/ATLAS in two unique ways with its Imaging Ultraviolet Spectrograph (IUVS) camera.
IUVS first took multiple images of 3I/ATLAS in several wavelengths, similar to using various filters on a camera.
Comet 3I/ATLAS offers unprecedented insight into an extrasolar system potentially billions of years older than our own.
The image taken by Hubble shows that comet 3I/ATLAS has a teardrop-shaped cocoon of dust off its solid, icy nucleus.
Hubble captured an image of the interstellar comet 3I/ATLAS on July 21, 2025.
On July 21, 2025, the comet 3I/ATLAS was 277 million miles from Earth.
3I/ATLAS is traveling through our Solar System at speeds up to 250,000 km/h and will soon vanish into interstellar space.
The ephemeris of 3I/ATLAS depended on the exact location of ExoMars TGO during its observations.
Collaboration among several ESA teams was necessary to reduce margins for greater accuracy in tracking 3I/ATLAS.
