Satellite Formation around the Largest Asteroids
The Astrophysical Journal LettersSatellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13 asteroids larger than 100 km are known to have satellites, but none have ...

Consequences of asteroid fragmentation during impact hazard mitigation [PDF]
, 2009 The consequences of the fragmentation of an Earth-threatening asteroid due to an attempted deflection are examined in this paper. The minimum required energy for a successful impulsive deflection of a threatening object is computed and compared to the ...

Passive sorting of asteroid material using solar radiation pressure [PDF]
, 2013 Understanding dust dynamics in asteroid environments is key for future science missions to asteroids and, in the long-term, also for asteroid exploitation.

Easily retrievable objects among the NEO population [PDF]
, 2013 Asteroids and comets are of strategic importance for science in an effort to understand the formation, evolution and composition of the Solar System. Near-Earth Objects (NEOs) are of particular interest because of their accessibility from Earth, but also

Synergistic approach of asteroid exploitation and planetary protection [PDF]
, 2012 The asteroid and cometary impact hazard has long been recognised as an important issue requiring risk assessment and contingency planning. At the same time asteroids have also been acknowledged as possible sources of raw materials for future large-scale ...

A smart cloud approach to asteroid deflection [PDF]
, 2011 This paper presents a novel idea for the successful deflection of asteroids. Adapted initially from the kinematic impactor approach, this new concept – Smart Cloud – combines the relative benefits of the ion beam shepard in providing a large cloud of ...

On the consequences of a fragmentation due to a NEO mitigation strategy [PDF]
, 2008 The fragmentation of an Earth threatening asteroid as a result of a hazard mitigation mission is examined in this paper. The minimum required energy for a successful impulsive deflection of a threatening object is computed and compared with the energy ...

Assessment on the feasibility of future shepherding of asteroid resources [PDF]
, 2012 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.

Opportunities for asteroid retrieval missions [PDF]
, 2013 Asteroids and comets are of strategic importance for science in an effort to uncover the formation, evolution and composition of the Solar System. Near-Earth Objects (NEOs) are of particular interest because of their accessibility from Earth, but also ...
