A Post‐Launch Summary of the Science of NASA's Psyche Mission

open access: yesAGU Advances
Astronomical observations indicate that asteroid (16) Psyche is a large, high‐density (likely >3,400 kg·m−3), metal‐rich (30–55 vol. %) asteroid. Psyche may be remnant core material or it could be a primordial, undifferentiated metal‐rich object.

Microtextures and structures in metal–sulfide grains in NWA 869 meteorite and their relation to thermal history of L‐chondrite parent body

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 616-631, March 2025.
Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.

Extremely strong polarization of an active asteroid (3200) Phaethon

open access: yesNature Communications, 2018
The near-Earth asteroid (3200) Phaethon is the parent body of the Geminid meteor stream. Phaethon is also an active asteroid with a very blue spectrum.

An automatic approach to exclude interlopers from asteroid families

open access: yes, 2017
Asteroid families are valuable source of information to many asteroid-related re- searches, assuming a reliable list of their members could be obtained. However, as the number of known asteroids increases fast it becomes more and more difficult to obtain

Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

Silicate–sulfide interaction within quenched melts of space weathered Ryugu grains

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The first few microns of the surface of airless bodies are subject to severe changes due to the harsh environment of space, known as space weathering. The Hayabusa2 sample return mission from the asteroid Ryugu provides the first opportunity to study these effects on a carbonaceous and hydrated body.

Asteroid mining [PDF]

open access: yes
The earliest studies of asteroid mining proposed retrieving a main belt asteroid. Because of the very long travel times to the main asteroid belt, attention has shifted to the asteroids whose orbits bring them fairly close to the Earth. In these schemes,

Erosive Hit-and-Run Impact Events: Debris Unbound

open access: yes, 2015
Erosive collisions among planetary embryos in the inner solar system can lead to multiple remnant bodies, varied in mass, composition and residual velocity. Some of the smaller, unbound debris may become available to seed the main asteroid belt.
