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.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

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

The 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

EU Space Law and Earth's Boundaries: Integrating Environmental Impact Assessment and Corporate Due Diligence

Global Policy, EarlyView.
ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.

A contact binary satellite of the asteroid (152830) Dinkinesh. [PDF]

Nature
Abstract Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques (that is, YORP, short for the Yarkovsky–O’Keefe–Radzievskii–Paddack effect) 1 to be a notable factor in their evolution 2

BYORP and Dissipation in Binary Asteroids: Lessons from DART

The 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 ...

Designs of multi-spacecraft swarms for the deflection of apophis by solar sublimation [PDF]

, 2009
This paper presents two conceptual designs of multi-spacecraft swarms used for deflecting Apophis. Each spacecraft is equipped with a solar concentrator assembly, which focuses the solar light, and a beaming system that projects a beam of light onto the ...
