A Change of the Rotation Period of Asteroid (65803) Didymos Caused by the DART Impact

The Planetary Science Journal
On 2022 September 26, the NASA Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the secondary component of the binary asteroid (65803) Didymos. This experiment tested the kinetic impactor technology for diverting dangerous asteroids.

Radiation Forces and Trajectory of Hayabusa2♯ Target 1998 KY26

The Astrophysical Journal Letters
Small near-Earth asteroid 1998 KY _26 has recently become an object of interest because it is the target of the Hayabusa2 ♯ mission and because challenges in fitting its astrometric data have led to classifying it as a dark comet.

Assessment on the feasibility of future shepherding of asteroid resources [PDF]

, 2010
Most plausible futures for space exploration and exploitation require a large mass in Earth orbit. Delivering this mass requires overcoming the Earth's natural gravity well, which imposes a distinct obstacle to any future space venture.

Categorization of Spatial and Temporal Ejecta Outcomes in Binary Systems Based on Variations of the Didymos System

The Planetary Science Journal
With the increasing number of binary asteroid systems being discovered, ejecta studies must expand from solely investigating single-body systems to modeling more complex multiple-body systems. For example, the Double Asteroid Redirection Test provides an

On the rotation of M-type asteroids: Statistical evidence for higher rotation rates

Icarus
Rotational dynamics of asteroids carry important information about their internal structure, collisional history and material composition. This work investigates whether M-type asteroids exhibit systematically higher rotation rates than the broader asteroid population.

Long-term Spectral Monitoring of Active Asteroid (6478) Gault: Implications for the H Chondrite Parent Body

The Planetary Science Journal
Active asteroid (6478) Gault underwent outbursts between late 2018 and early 2019 with tails morphologically similar to the ejecta from Dimorphous following the Double Asteroid Redirection Test impact.

Evidence for YORP-induced Spin Deceleration in Asteroid (433) Eros

The Astrophysical Journal
Theoretically, the Yarkovsky–O’Keefe–Radzievskii–Paddack (YORP) effect induced by thermal reemission from asteroid surfaces can either accelerate or decelerate their rotation.
