This paper presents a comprehensive review of the science and technology of accessing
near-Earth asteroids (NEAs), or making them accessible, for obtaining both information and …

This paper presents an overview of space mission concepts for disrupting or pulverizing
hazardous asteroids, especially with warning time shorter than approximately 10 years. An …

An asteroid impact can potentially destroy life on this planet. Therefore, asteroids should be
prevented from impacting the Earth to impede severe disasters. Nuclear explosions are …

Explosion deflection has recently become an important topic in hazardous asteroid
deflection. Changes in asteroid velocity and angular velocity, as well as the degree of …

To prevent catastrophic asteroid–Earth collisions, it has been proposed to use nuclear
explosives to deflect away earthbound asteroids. However, this policy of nuclear deflection …

While the most likely near-term threat from near-Earth objects (NEOs) is that of a low-altitude
airburst, the expected energy of an event such as Tunguska would be devastating in a …

This final technical report describes the results of a NASA Innovative Advanced Concept
(NIAC) Phase 2 study entitled" An Innovative Solution to NASA's NEO Impact Threat …

This paper summarizes the perspectives of panelists participating in the discussion of
“Nuclear Devices for Planetary Defense”(PANEL-17) at the AIAA ASCEND conference in …

Planetary defense scientists frequently consider nuclear explosive devices (NED) among
the suitable tools for deflection of near-Earth objects. Despite the convenient physical …

This paper presents the development of a new Graphics Processing Unit (GPU) accelerated
computational tool for asteroid disruption techniques. Numerical simulations are completed …
