Rudarsko-geološko-naftni Zbornik, 2016 Asteroids are the largest minor bodies in the Solar System. Nowadays they are in the research focus due to several facts about them: first, a subclass of asteroids can collide with Earth, and consequences of such a collision are dramatic.

Optimal impact strategies for asteroid deflection [PDF]
, 2008 This paper presents an analysis of optimal impact strategies to deflect potentially dangerous asteroids. To compute the increase in the minimum orbit intersection distance of the asteroid due to an impact with a spacecraft, simple analytical formulas are

Nature, 2009 The production of terrestrial andesites in subduction zones is well established. Day et al. describe two examples of meteorites (GRA 06128 and GRA 06129) that they claim to represent "an entirely new mode of generation of andesite crust compositions" on asteroids; this suggestion has wide implications for the generation of andesitic planetary crusts in

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 ...

Vestnik oftal'mologii, 2019 The article analyzes existing information on clinical and experimental studies of vitreous changes in asteroid hyalosis, historical aspects of how this condition was studied over the past hundred years, its occurrence and pathogenesis. Results of various studies were used to evaluate current understanding of the forms and elemental composition of ...

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

Experimental analysis of laser ablated plumes for asteroid deflection and exploitation [PDF]
, 2013 It has been theoretically demonstrated that laser ablation is effective in the potential deflection and mitigation of asteroids. However, there have been few experimental studies to support this claim.

Light-touch2 : a laser-based solution for the deflection, manipulation and exploitation of small asteroids [PDF]
, 2013 This paper presents the preliminary mission and system analysis of a small-scale, light-weight system for the deflection, manipulation and exploitation of small size asteroids. The system proposed in this paper, called Light-Touch2, uses lasers to ablate

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.
