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 ...

Didymos’s Reshaping Scale Revealed by Detection of Its Spin Slow-down
The Planetary Science JournalNASA’s Double Asteroid Redirection Test (DART) conducted a successful kinetic deflection experiment on Dimorphos, the smaller companion in the near-Earth binary asteroid (65803) Didymos.

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids
Meteoritics &Planetary Science, EarlyView.Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

BYORP and Dissipation in Binary Asteroids: Lessons from DART
The Planetary Science JournalThe near-Earth binary asteroid Didymos was the target of the planetary defense demonstration mission DART in 2022 September. The smaller binary component, Dimorphos, was impacted by the spacecraft in order to measure momentum transfer in kinetic impacts ...

The Perturbed Full Two-body Problem: Application to Post-DART Didymos
The Planetary Science Journal, 2023 With the successful impact of the NASA Double Asteroid Redirection Test (DART) spacecraft in the Didymos–Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid dynamics.

Meteoritics &Planetary Science, EarlyView.Abstract This study investigates the spatial distribution and spectral characteristics of the broad hydration feature near 3 μm across the surface of asteroid (101955) Bennu using OVIRS (OSIRIS‐REx Visible and InfraRed Spectrometer) data. We analyzed multiple global OVIRS data sets obtained at different times throughout the Bennu day, revealing ...

Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
The Astrophysical Journal Letters, 2023 The impact of the Double Asteroid Redirection Test spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos’s orbit substantially, largely from the ejection of material.

Thermal history, collisional history, and structure of the CK‐chondrite parent body
Meteoritics &Planetary Science, EarlyView.Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.

DART Impact Ejecta Plume Evolution: Implications for Dimorphos
The Planetary Science JournalThe NASA Double Asteroid Redirection Test (DART) spacecraft impacted the moon Dimorphos of the [65803] Didymos binary system and changed the binary orbit period, demonstrating asteroid deflection by a kinetic impact and indicating that more momentum was ...
