Tracing the main belt origins of S-complex near-Earth objects: From space mission targets to meteorite sources
P. N. Simon, P. Vernazza, M. Marsset +5
Context. Space missions to near-Earth objects (NEOs) provide unique opportunities to study and characterise their physical and compositional properties. Interpreting these results…
Shape, regolith size and thickness, SMFe^0 content, and spectral type of Tianwen-2 target asteroid (469219) Kamo'oalewa
Pengfei Zhang, Guozheng Zhang, Yongxiong Zhang +13
China's Tianwen-2 spacecraft will return samples from the near-Earth asteroid (469219) Kamo'oalewa. We previously reported that Kamo'oalewa develops an LL-chondrite-compositional,…
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…
Shaken, not stirred: inefficient mixing of CM- and CI-like materials
Sarah E. Anderson, Pierre Vernazza, Miroslav Broz
A recent study suggests that CM chondrite-like planetesimals formed in the vicinity of Saturn, in a pressure bump outside the gap carved by proto-Jupiter. While a fraction of these…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
A portrait throughout perihelion of the NH-rich interstellar comet 2I/Borisov
Sophie E. Deam, Michele T. Bannister, Cyrielle Opitom +12
The interstellar comet 2I/Borisov is the first interstellar object where compositional characterisation was possible throughout its entire perihelion passage. We report all 16 epoc…
Perihelion history and atmospheric survival as primary drivers of the Earth`s meteorite record
Patrick M. Shober, Hadrien A. R. Devillepoix, Jeremie Vaubaillon +7
Models predict that more than half of all impacting meteoroids should be carbonaceous, reflecting the abundance of carbon-rich asteroids in the main belt and near-Earth space. Yet…
The Massalia asteroid family as the origin of ordinary L chondrites
Michaël Marsset, Pierre Vernazza, Miroslav Brož +10
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…
Multiple and Fast: The Accretion of Ordinary Chondrite Parent Bodies
P. Vernazza, B. Zanda, R. P. Binzel +7
Although petrologic, chemical and isotopic studies of ordinary chondrites and meteorites in general have largely helped establish a chronology of the earliest events of planetesima…
