162173 Ryugu: Constraining Mineralogical Composition in Preparation for
Spacecraft Operations
, 2017 Asteroids that are targets of spacecraft missions are interesting because
they present us with an opportunity to validate ground-based spectral
observations. One such object is near-Earth asteroid (NEA) (162173) Ryugu,
which is the target of the Japanese Becker, Kris J., Cloutis, Edward A., Corre, Lucille Le, Li, Jian-Yang, Reddy, Vishnu, Sanchez, Juan A., Sugita, Seiji, Takir, Driss, Tatsumi, Eri, Thirouin, Audrey +9 morecore +1 more sourceIron and copper sulfides in asteroid (162173) Ryugu: Formation conditions and a comparison to the CI and CY chondrites

Journal of Geophysical Research: Planets, 2020 AbstractObservations of the magnetization state of asteroids indicate diverse properties. Values between 1.9 10 Am /kg (Eros) and 10 Am /kg (Braille) have been reported. A more detailed understanding of asteroidal magnetic properties allows far‐reaching conclusions of the magnetization mechanism as well as the strength of the magnetic field of the ...Hercik, D., Auster, H-U., Constantinescu, D., Blum, J., Fornacon, K.H., Fujimoto, M., Gebauer, K., Grundmann, J.

Meteoritics &Planetary Science, EarlyView.Abstract
We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.B. Marty, L. Zimmermann, E. Füri, D. V. Bekaert, J. J. Barnes, A.
