Analysis of Ryugu Fluid Inclusions: An Update [PDF]
The most direct and convincing evidence for the presence of water and organic molecules on protoplanetary bodies is provided by fluid inclusions trapped in secondary minerals.Chan, Queenie, Dolocan, Andrei, Le, Loan, Bodnar, Robert, Matsumoto, Megumi, Zolensky, Michael, Gearba, Iona, Tsuchiyama, Akira, Han, JangMi, Hanna, Romy, Ireland, Trevor +10 morecore +8 more sourcesThe Solar System calcium isotopic composition inferred from Ryugu samples

Meteoritics &Planetary Science, EarlyView.Abstract
Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...Scott A.

We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...Gary R.
