Rubble piles asteroids consist of reassembled fragments from shattered monolithic asteroids
and are much more abundant than previously thought in the solar system. Although …

Abstract NASA's Double Asteroid Redirection Test (DART) mission is the first full-scale test
of the kinetic impactor method for asteroid deflection, in which a spacecraft intentionally …

Contact binary asteroids are ubiquitous in the solar system: the Kuiper belt, main belt, and
near-Earth populations all house these complex aggregates. Although contact binaries …

The effects of projectile/target impedance matching and projectile shape on energy,
momentum transfer and projectile melting during collisions are investigated by numerical …

Diverting hazardous small bodies on impact trajectories with the Earth can in some
circumstances be impossible without risking disrupting them. Disruption is a much more …

One of the mechanisms of destruction of a solid is the formation and growth of “micro” and
“macro” cracks. This task is especially acute for space objects. A microcrack in the body of …

In 2005, the United States Congress passed a bill mandating the detection, tracking,
cataloguing and characterization of 90\% of the 140 meter and larger near-Earth objects …

The threat of asteroid impacts on the Earth can be mitigated through deflection missions.
The deflection capability has previously been omitted in asteroid impact risk analysis work …

Near-Earth asteroids pose a considerable threat to the safety of the Earth, where their impact
would cause a huge disaster. For asteroid deflection, kinetic impact is an effective strategy …

All celestial bodies have defects in the form of cracks. Some of the bodies are large.
Colliding with such objects can be dangerous. Therefore, the problem of grinding such …
