Tracing the main belt origins of S-complex near-Earth objects: From space mission targets to meteorite sources

Large main-belt asteroids with visible geometric albedos below 0.1 are predominantly classified within the C- and X-complex spectroscopic classes. C-type and dark X-type asteroids…
Tianwen-2 target asteroid (469219) Kamo'oalewa probably develops an Itokawa-compositional but ultra-highly space-weathered surface
Pengfei Zhang, Guozheng Zhang, Zichen Wei +45
China's Tianwen-2 mission plans to return samples from a small, rapidly spinning Earth quasi-satellite (469219) Kamo'oalewa. Previous studies linked Kamo'oalewa to lunar compositio…
The Nysa family as the main source of unequilibrated LL ordinary chondrites
M. Marsset, P. Vernazza, M. Brož +16
Context. The origin of the petrologic diversity observed in ordinary chondrites (OCs), the most common meteorites on Earth, remains debated. Competing models invoke either depth-de…
Source regions of carbonaceous meteorites and NEOs
M. Brož, P. Vernazza, M. Marsset +15
The present work aims to determine the source regions of carbonaceous chondrites (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). We studied 38 individual asteroid families, inclu…
The Massalia asteroid family as the origin of ordinary L chondrites

Studies of micrometeorites in mid-Ordovician limestones and Earth's impact craters indicate that our planet witnessed a massive infall of ordinary L chondrite material 466 million…
Young asteroid families as the primary source of meteorites
M. Brož, P. Vernazza, M. Marsset +4
Understanding the origin of bright shooting stars and their meteorite samples is among the most ancient astronomy-related questions that at larger scales has human consequences [1-…
The New Horizons Extended Mission Target: Arrokoth Search and Discovery
Marc W. Buie, John R. Spencer, Simon B. Porter +37
Following the Pluto fly-by of the New Horizons spacecraft, the mission provided a unique opportunity to explore the Kuiper Belt in-situ. The possibility existed to fly-by a Kuiper…
Near-IR Spectral Observations of the Didymos System -- Daily Evolution Before and After the DART Impact, Indicates Dimorphos Originated from Didymos
David Polishook, Francesca E. DeMeo, Brian J. Burt +4
Ejecta from Dimorphos following the DART mission impact, significantly increased the brightness of the Didymos-Dimorphos system, allowing us to examine sub-surface material. We rep…
Compositional properties of planet-crossing asteroids from astronomical surveys
A. V. Sergeyev, B. Carry, M. Marsset +8
Context. The study of planet-crossing asteroids is of both practical and fundamental importance. As they are closer than asteroids in the Main Belt, we have access to a smaller siz…
Isolating the mechanisms for asteroid surface refreshing
F. E. DeMeo, M. Marsset, D. Polishook +10
Evidence is seen for young, fresh surfaces among Near-Earth and Main-Belt asteroids even though space-weathering timescales are shorter than the age of the surfaces. A number of me…
Spectral evolution of dark asteroid surfaces induced by space weathering over a decade
Sunao Hasegawa, Francesca E. DeMeo, Michael Marsset +20
The surface of airless bodies like asteroids in the Solar System are known to be affected by space weathering. Experiments simulating space weathering are essential for studying th…
Connecting Asteroids and Meteorites with visible and near-infrared spectroscopy
Francesca E. DeMeo, Brian J. Burt, Michaël Marsset +12
We identify spectral similarities between asteroids and meteorites. We identify spectral matches between 500 asteroid spectra and over 1,000 samples of RELAB meteorite spectra over…
The debiased compositional distribution of MITHNEOS: Global match between the near-Earth and main-belt asteroid populations and excess of D-type Near-Earth Objects
Michaël Marsset, Francesca E. DeMeo, Brian Burt +10
We report 491 new near-infrared spectroscopic measurements of 420 near-Earth objects (NEOs) collected on the NASA InfraRed Telescope Facility (IRTF) as part of the MIT-Hawaii NEO S…
The appearance of a 'fresh' surface on 596 Scheila as a consequence of the 2010 impact event
Sunao Hasegawa, Michael Marsset, Francesca E. DeMeo +8
Dust emission was detected on main-belt asteroid 596 Scheila in December 2010, and attributed to the collision of a few-tens-of-meters projectile on the surface of the asteroid. In…
A new approach to feature-based asteroid taxonomy in 3D color space: 1. SDSS photometric system
Dong-Goo Roh, Hong-Kyu Moon, Min-Su Shin +1
The taxonomic classification of asteroids has been mostly based on spectroscopic observations with wavelengths spanning from the VIS to the NIR. VIS-NIR spectra of 2500 aster…
