Effect of Irregular Particle Shape in Simulations of Tidal Disruption and Reaccumulation of Small Solar System Bodies

open access: yesThe Planetary Science Journal
Small solar system bodies subjected to planetary tides may be resurfaced, distorted, reshaped, split into binary or higher-multiple systems, or fragmented entirely. We investigate the effects of particle shape on numerical models of tidal deformation and

Stereophotoclinometry for OSIRIS-REx Spacecraft Navigation

open access: yesThe Planetary Science Journal, 2023
We summarize a decade of effort by the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) mission team to build up the unique capabilities, processes, and procedures required to accomplish the ...

TUMBUKAN TAK-ELASTIK PARTIKEL SEBAGAI MODEL TERBENTUKNYA ASTEROID

open access: yesSpektra: Jurnal Fisika dan Aplikasinya, 2017
Abstrak Suatu asteroid diduga merupakan kumpulan partikel yang bertumbukan tak-elastik sehingga membentuk suatu agregat. Ikatan yang terjadi antar partikel diasumsikan hanyalah disebabkan gaya gravitasi.

BYORP and Dissipation in Binary Asteroids: Lessons from DART

open access: yesThe Planetary Science Journal
The 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 ...

System Modeling and Simulation of TianWen-2 Sampling on an Asteroid Regolith Surface

open access: yesSpace: Science & Technology
As 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 ...

The Secular Dynamical Evolution of Binary Asteroid System (65803) Didymos Post-DART

open access: yesThe Planetary Science Journal
The 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.

Recurring Activity Discovered on Quasi-Hilda 2009 DQ118

open access: yesThe 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 ...

Dynamical evolution of cometary asteroids [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
ABSTRA C T We present results from long-term numerical integrations of hypothetical Jupiter-family comets (JFCs) over time-scales in excess of the estimated cometary active lifetime. During inactive periods these bodies could be considered as ‘cometary’ near-Earth objects (NEOs) or ‘cometary asteroids’. The contribution of cometary asteroids to the NEO

Mineral Extraction Scenarios From an Asteroid via Optimization Considering Rotational Dynamics

open access: yesIEEE Access
This study examines how removing surface materials affects the rotational dynamics of an asteroid to design efficient asteroid mining plans. The simulations solve Euler’s equations and track variations in the inertia tensor, angular momentum, and ...
