Mirror formation control in the vicinity of an asteroid [PDF]
, 2008 Two strategies are presented for the positioning and control of a spacecraft formation designed to focus sunlight onto a point on the surface of asteroid, thereby sublimating the material and ejecting debris creating thrust.

Consequences of asteroid fragmentation during impact hazard mitigation [PDF]
, 2010 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.

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 ...

No Place to Hide? Regional Resilience and Vulnerability to Global Catastrophic Risk. [PDF]
Glob ChallNo location on Earth withstands every global catastrophe. This review maps the geographic, institutional and infrastructural factors shaping resilience to nuclear, volcanic and impact winters, infrastructure loss and pandemics. Geographic isolation, food self‐sufficiency, strong governance and decentralization improve resilience across scenarios ...

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 ...

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.
