Considerations on the process of target selection for the Comet Interceptor mission
C. Snodgrass, E. Mazzotta Epifani, C. Tubiana +27
Comet Interceptor is an ESA science mission with payload contributions from ESA Member States and with an international participation by JAXA. It is the first mission that is being…
Evolutionary Processes in the Centaur Region
Rosita Kokotanekova, Aurélie Guilbert-Lepoutre, Matthew M. Knight +1
Centaurs populate relatively short-lived and rapidly evolving orbits in the giant-planet region and are believed to be one of the solar system's most complex and diverse population…
Recent Chemo-morphological Coma Evolution of Comet 67P/Churyumov-Gerasimenko
Brian P. Murphy, Cyrielle Opitom, Colin Snodgrass +5
We present VLT/MUSE observations of comet 67P/Churyumov-Gerasimenko during its 2021 perihelion passage, from which we generated simultaneous maps of dust, [OI], C, NH, and…
Snapshot of a new interstellar comet: 3I/ATLAS has a red and featureless spectrum
Cyrielle Opitom, Colin Snodgrass, Emmanuel Jehin +19
The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and compositi…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario Jurić +305
We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
Multi-wavelength JWST observations of (3200) Phaethon show a dehydrated object with an aqueously altered origin
Cristina A. Thomas, Andrew S. Rivkin, Ian Wong +10
We present JWST observations of the near-Earth asteroid (3200) Phaethon using the Near-Infrared Camera (NIRCam), Near-Infrared Spectrograph (NIRSpec), and Mid-Infrared Instrument (…
First JWST spectrum of distant activity in Long Period Comet C/2024 E1 (Wierzchos)
Colin Snodgrass, Carrie E. Holt, Michael S. P. Kelley +10
We observed the new Long Period Comet C/2024 E1 (Wierzchos), inbound at 7 au from the Sun, using the NIRSpec integral field unit on JWST. The spectrum shows absorption features due…
The Volatile Composition and Activity Evolution of Main-Belt Comet 358P/PANSTARRS
Henry H. Hsieh, John W. Noonan, Michael S. P. Kelley +17
We report the detection of water vapor associated with main-belt comet 358P/PANSTARRS on UT 2024 January 8-9 using the NIRSPEC instrument aboard JWST. We derive a water production…
VLT/MUSE Characterisation of Dimorphos Ejecta from the DART Impact
Brian P. Murphy, Cyrielle Opitom, Colin Snodgrass +8
We have observed the Didymos-Dimorphos binary system with the MUSE integral field unit spectrograph mounted at the Very Large Telescope (VLT) pre and post-DART impact, and captured…
Photometry of the Didymos system across the DART impact apparition
Nicholas Moskovitz, Cristina Thomas, Petr Pravec +78
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos. This demonstrated the…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
Orbital Period Change of Dimorphos Due to the DART Kinetic Impact
Cristina A. Thomas, Shantanu P. Naidu, Peter Scheirich +46
The Double Asteroid Redirection Test (DART) spacecraft successfully performed the first test of a kinetic impactor for asteroid deflection by impacting Dimorphos, the secondary of…
Observational and Dynamical Characterization of Main-Belt Comet P/2010 R2 (La Sagra)
Henry H. Hsieh, Bin Yang, Nader Haghighipour +36
We present observations of comet-like main-belt object P/2010 R2 (La Sagra) obtained by Pan-STARRS 1 and the Faulkes Telescope-North on Haleakala in Hawaii, the University of Hawai…
