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 ...

Technologized Reproduction in Space: A Space‐Bioethical Case for Assisted Procreation
Bioethics, EarlyView.ABSTRACT With the increasing feasibility of space colonization, the issue of reproduction in space is becoming more relevant. As new settlements on the Moon, Mars, and other celestial bodies emerge, ensuring generational continuity will be essential for the survival and growth of these communities.

System Modeling and Simulation of TianWen-2 Sampling on an Asteroid Regolith Surface
Space: Science & TechnologyAs China’s first asteroid exploration mission, the TianWen-2 spacecraft mainly focuses on surface sampling on the near-Earth asteroid 2016 HO3. Different from the usual sampling strategy of releasing a small lander or ejecting a projectile, the whole ...

Meteoritics &Planetary Science, EarlyView.Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

The Secular Dynamical Evolution of Binary Asteroid System (65803) Didymos Post-DART
The Planetary Science JournalThe successful impact of NASA’s DART mission with Dimorphos, the secondary body of binary asteroid system (65803) Didymos, altered the attitude, shape, and orbit of Dimorphos.

Scaling forces to asteroid surfaces: The role of cohesion
, 2010 The scaling of physical forces to the extremely low ambient gravitational acceleration regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found that van der Waals cohesive forces between regolith grains on asteroid ...

Noble gases and nitrogen in material from asteroid Bennu
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.

Recurring Activity Discovered on Quasi-Hilda 2009 DQ118
The Astrophysical Journal Letters, 2023 We have discovered two epochs of activity on quasi-Hilda 2009 DQ _118 . Small bodies that display comet-like activity, such as active asteroids and active quasi-Hildas, are important for understanding the distribution of water and other volatiles ...
