Passive sorting of asteroid material using solar radiation pressure [PDF]

open access: yes, 2014
Understanding dust dynamics in the vicinity of asteroids is key for future science missions and, in the long-term, for asteroid exploitation. This paper analyses the feasibility of manipulating asteroid material by means of solar radiation pressure.

Microstructural evidence for multiple generations of sulfide precipitation and impact‐induced thermal alteration under acidic conditions on Asteroid Ryugu

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2201-2217, September 2026.
Abstract Here we report on the microstructure and chemistry of sulfide minerals returned from asteroid (162173) Ryugu. We identify a unique sulfide population in particle A0016 composed of violarite (FeNi2S4), pyrite (FeS2), chalcopyrite (CuFeS2), pyrrhotite (Fe1‐xS), and pentlandite ([Fe,Ni]9S8).

Inflatable Dome for Moon, Mars, Asteroids, and Satellites

open access: yesAIAA SPACE 2007 Conference & Exposition, 2007
On a planet without atmosphere, sustaining human life is very difficult and dangerous, especially during short sunlit period when low temperature prevails. To counter these environmental stresses, the author offer an innovative artificial "Evergreen" dome, an inflated hemisphere with interiors continuously providing a climate like that of Florida ...

The first discovery of a shocked, metasomatised CV3 chondrule‐fragment in a (Al,Cu)‐bearing micrometeorite

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2269-2283, September 2026.
Abstract We report the discovery of the second (Al,Cu)‐alloy–bearing micrometeorite, FB‐A2, recovered from Mount Gariglione (southern Italy), representing the sixth such occurrence worldwide. Although chondritic in nature, FB‐A2 differs markedly from previously described microspherules.

An Updated Shape Model of Dimorphos from DART Data

open access: yesThe Planetary Science Journal
Dimorphos was the target of the Double Asteroid Redirection Test (DART) mission. This paper summarizes the properties of an updated shape model of Dimorphos, describes the differences between the updated shape model and an earlier version published by ...

Fully Coherent Model of Dynamics around Binary Asteroids: Application to Didymos and the DART Impact

open access: yesThe Planetary Science Journal
The dynamical environment around binary asteroids has been studied in depth, but these models typically make assumptions about the eccentricity, shapes, or rotational stability of the asteroids.

When Communication Enables Catastrophe: Nuclear Risk and the Short Lifetimes of Technological Civilizations

open access: yesRisk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT The Fermi paradox may partly reflect technological self‐destruction acting as a Great Filter during post‐industrial development. Because the empirical record consists of a single civilization observed over an eighty‐year nuclear age, the exercise reported here is best understood as a structured, historically anchored scenario analysis rather ...

Tour of Asteroids for Characterization Observations (TACO): A Planetary Defense Asteroid Tour Concept

open access: yesThe Planetary Science Journal
Asteroid impacts potentially represent a substantial threat to humanity, but one that we can plan for and mitigate. To design an effective asteroid mitigation mission, however, it is important to have as detailed knowledge of the asteroid threat as ...
