The Increasingly Strange Polarimetric Behavior of the Barbarian Asteroids
The Planetary Science Journal, 2023 Polarization phase-curve measurements provide a unique constraint on the surface properties of asteroids that are complementary to those from photometry and spectroscopy and have led to the identification of the “Barbarian” asteroids as a class of ...

Surface Properties of Near-Sun Asteroids
The Planetary Science Journal, 2022 Abstract Near-Earth asteroids (NEAs) with small perihelion distances reach subsolar temperatures of ≥1000 K. They are hypothesized to undergo “supercatastrophic” disruption, potentially caused by near-Sun processes such as thermal cracking, spin-up, meteoroid impacts, and subsurface volatile release, all of which are likely to cause ...

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.

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 ...

Asteroid deflection and exploitation : possible synergies [PDF]
, 2011 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 ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Asteroid resource map for near-Earth space [PDF]
, 2011 Most future concepts for the exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this required mass from the Earth’s surface increases cost due to the large energy input necessary to move mass out of the ...

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